Known Issues:

• A File -> SaveAs command in Dynamo running in the context of a host can break element binding with the currently open host document. This is a change in behavior from Dynamo 2.17. To preserve element binding data, choose to only Save the DYN file to save changes.
• Opening and/or running a Dynamo graph in the context of a host application no longer marks the DYN dirty and therefore does not prompt a Save on closing it. This can lead to any element binding data generated on the previous execution being lost as it will not be saved to the DYN file. This in turn will lead to element binding being broken on a subsequent Open and Run of the same graph. To prevent this it is necessary to always save the workspace after a graph run even if it isn't marked dirty.

Binary Delivery Changes:

2.18 introduces dependencies on

• Python.Included.SciPy PR

Known Issues:

• Language selection will default to English in Dynamo due to technical limitations that require re-architecting part of Dynamo. This means a host application (i.e. Revit, Civil 3D) in a language (i.e. German, Polish) will open up in English until set back to a users chosen language. Once set, this will persist for all future sessions.
• A File -> SaveAs command in Dynamo running in the context of a host can break element binding with the currently open host document. This is a change in behavior from Dynamo 2.17. To preserve element binding data, choose to only Save the DYN file to save changes.

Known Issues:

• Dynamo can hang or crash on certain computers at startup time due to WPF render thread failures. Currently, these issues have been found to occur only on Windows machines with multiple GPUs and look to be related to WebView2. There are a couple of workarounds that one can try before you restart Dynamo:
  • Set the UseHardwareAcceleration property to false in the Dynamo preference settings DynamoSettings.xml file and restart Dynamo.
  • With UseHardwareAcceleration set to true, force your Dynamo application (e.g. DynamoSandbox.exe or Revit.exe) to run with the high-performance GPU on your machine and try relaunching Dynamo.
  • Disable one of the GPUs and try relaunching Dynamo.

2.0.3 (hotfix for DynamoRevit 2017 - 2019 users)

• LibrarieJS crash was fixed when loading packages containing many custom nodes (PR)
• Many language level fixes cherry picked from 2.2 release: (PR) These changes include:
  • Do not allow indexing into a list or single item with a [] operator that is greater than the rank of the list
  • Allow string indexing
  • Fix a case where replication would fail with nested sublists with null or empty lists as first item in outer list.
  • Lists containing elements of different ranks, but with same type ie. [[[2]],[1]] will now replicate correctly. There is still one remaining failing case when the elements are of different types: [["string"],[1]], instead the node will return null.
• Maintain imperative for loop behavior allowing iteration over a single item (PR)

Note: regarding indexing change for single items.

For example in Dynamo 2.0.2 the designScript 100[0]; Would return 100, but this should have thrown an indexing exception as it did in Dynamo 1.3.

If you need this behavior you can still use List.FirstItem or List.GetItemAtIndex

Known Issues:

2.0.3 Sandbox will not connect to the package manager after August 3 TLS cut over. Use a newer sandbox available from https://dynamobuilds.com or use Dynamo from an up to date Revit version.

• Files from Dynamo 2.12 or newer containing selection or dropdown nodes, which are marked IsInput fail to open. This will be fixed in a newer version of Dynamo, for other workarounds see this forum post

Known Issues:

• Nodes

  • Dictionary links for individual nodes are removed from each node, user can still access Dictionary using the links on startup page

• DesignScript

  • Nested associative blocks inside of imperative blocks causes a crash

  • DesignScript does not support syntax for string literals. This is by design and the use of String node is recommended for string literals for now. Refer to the "Bug Fixes" section of 1.3 Release Notes for an explanation of escape characters and character escape sequences.

  • There are existing bugs with nodes not replicating properly over nested homogeneous lists with the first element having a rank (dimensionality) smaller than the rank of the element(s) following it. There is also an existing bug with nodes not replicating properly over nested heterogeneous lists (with each element having rank greater than or equal to zero). For example, A nested list containing a list of integers and a list of points would not replicate properly ([[1,2,3],[p1,p2,p3]]).

  • There is a known issue with replication failing when the first item in nested list data structure is [null] or an empty list. These issues can manifest as replication failing to pass the correct data to nodes, and an error suggesting the correct method cannot be found.

    • workaround: use list.clean to remove the null or empty lists from your data structure.

• .Net 4.7

  • Dynamo now targets .net 4.7 - Microsoft has acknowledged a bug which manifests as a hang when interacting with certain WPF controls when using screen resolution scaling. If you encounter hangs/freezes when using watch nodes, this is likely the cause: https://github.com/Microsoft/dotnet/issues/604. We are evaluating solutions and will review when Microsoft releases an update fixing this issue. In the meantime we have rolled back to some WPF 4.5 algorithms to avoid the issue.
  • DynamoCore public nugets lib paths have been updated to reflect .Net 47 migration, 3rd party developers using 2.1.0 nugets will most likely need to update their project reference settings to continue building the project.

• DynamoRaaS package AKA Dynamo Daylighting Workflows package is no longer supported in DynamoCore by default.

• Change from XML based file format to JSON to facilitate future use and reuse of Dynamo graphs in non-Windows, web-friendly environemnts. With the exception of some deprecated functionality as noted below, all information in 1.x files will be preserved and migrated to the new 2.0 format. To prevent data loss, a copy of the 1.x file will be saved in the specified backup location as [original_Name]_xml.dyn.
• A new web-compatible node library that can be reused in other contexts has been introduced
  • Custom nodes and packages will now appear separately from out-of-the-box nodes in the Add-ons section of the library
  • Out-of-the-box nodes have been reorganized in the library to allow for easier browsing
• Nodes without DesignScript equivalents have been renamed without the misleading "dot" notation, e.g., "List.Create" is now "List Create"
• Several DesignScript changes have been made to simplify the language for easier maintenance and increasing legibility. See the the wiki for a list of changes.
• A new Dictionary data type has been introduced to DesignScript, allowing users to index collections of data with Strings (instead of integers) and pass them around as compact custom data objects identified by a “key value”.
  • The introduction of this new data type also introduces new initialization syntax for for both dictionaries and lists. Dictionaries use the following syntax {key:value}; Lists use the following syntax [value,value,value]
• Python editor improvements including multiple editor window support, re-execution capability from the window, and custom template loading.
• Integer data type promoted to 64 bit
• Addition and update of nodes including:
  • Color Picker node
  • File.AppendText
  • GetDirectory Contents with recursive access to subfolders
  • Updated ImportExcel node to suppress launching of Excel window
  • Modulo operator (%) now follows the standard behavior of Python, Excel, and Google calculator, returning a modulo which follows the sign of the divisor.
• Introduced new "Auto" lacing option on nodes. Nodes set to "Shortest" lacing in 1.x graphs will automatically be migrated to have "Auto" lacing in 2.0.
• Method resolution errors are more succinct and contextually relevant
• Dynamo Sandbox is delivered with 2.0 installer in "Program Files\Dynamo\Dynamo Core\2"

Deprecated Functionality:

• Redundant nodes have been consolidated. For example, instead of List.Flatten and Flatten, or List.Count and Count, there is simply List.Flatten and List.Count
• Overload nodes that had inputs that varied in rank only have been consolidated.
• Drag and drop of nodes from the library to specific locations in the canvas is no longer supported
• Presets
• Preview Upstream
• Saved pin state of the preview bubble
• NewtonRootFind1DNoDeriv and NewtonRootFind1DWithDeriv
• Custom nodes cannot be located among out-of-the-box nodes and categories
• Package library locations on disk are no longer automatically migrated from earlier versions to 2.0 package locations.
• Number nodes no longer support range syntax. Note: 1.x graphs containing number nodes with range syntax will automatically be migrated to code block nodes in 2.0.

Dynamo for Revit issues:

• Revit Model Curves, Detail curves, Tags, and Text notes that are selected are no longer automatically rendered in geometry previews. This is by design to make them consistent with other Revit elements and prevent certain crashes. Users can still use Element.Geometry and Element.Curve to visualize the curves. Tags and Text notes do not have real geometry to visualize, as they are View specific elements.
• Due to conflicts with the Chromium Embedded Framework (CEF) component found in Revit 2019, the library can scroll erratically.
• Some keyboard shortcuts do not work in Dynamo for Revit 2019.0. These include Ctrl+Z for Undo and Ctrl+C/Ctrl+V for Copy/Paste.
• When upgrading with the Green Cloud in Revit, two dialogs will appear. In order for the update to occur, you must close Revit before closing the second dialog.

For Package Developers:

• Please consult the list of API changes for any ZeroTouch or NodeModel migrations that will be necessary to implement: https://github.com/DynamoDS/Dynamo/wiki/APIChanges. Additionally, you can utilize this guide to help you with the transition from 1.x to 2.0: https://github.com/DynamoDS/Dynamo/wiki/Update-Packages-from-1.3-to-2.0.
• Introduction of new dictionary and list syntax may cause issues with ZeroTouch inputs, specifically for default arguments. When opening graphs, migration of 1.x lists to new 2.0 syntax will be done for all cases except for default argument attributes in ZeroTouch nodes.

Bug Fixes:

• Previous version of Dynamo accumulated at least 10 mb of memory on open of each graph
• Volume conversion fixed in "Convert Between Units" node

Known Issues:

• For custom nodes, using dot-notation in node Names or Categories will result in additional nested sub-categories. The "." will work as a delimiter to determine the additional hierarchy. This is new behavior in the library for Dynamo 2.0.
• Dynamo 2.0 has a conflict with Revit 2018.2’s implementation of PnID Modeler resulting in a blank library browser pane. This issue is not present in 2018.1 or 2018.3, or Revit 2019, just 2018.2. If you want to use 2.0 with Revit 2018.2, you will need to remove the the manifest file C:\Program Files\Autodesk\Revit 2018\AddIns\PnIDModeler\PnIDModeler.addin
• If the network drive pointed to by “Manage Node and Package paths” is > 1TB in size loading Dynamo may take a minute or more, irrespective of actual package size. We recommend drive size of 100GB or smaller.
• Toggling the freeze state can cause a node to be executed twice after editing a Code Block Node.
• Installers fail to prompt for missing VC++ components which causes Dynamo to silently crash at load time
• Packages that deliver DynamoServices.dll may have corrupted multi-output port nodes; instead of multiple output ports, they will be collapsed into a single output port.
• Some JSON graphs may open and erroneously appears to have unsaved changes as shown by the asterisks in the workspace tab.
• If your workstation contains multiple major versions of Dynamo, e.g, Dynamo 1.x and Dynamo 2.x, Dynamo Player will start with whichever version you select for Dynamo for that session.
• Custom node libraries that contain the same category and node names result in unexpected library organization.
• Special characters are ignored in the Library Search.
• Namespace conflicts in Imperative Blocks cause unexpected input ports to appear. See the Github issue for more info. To get around this, define the function outside of the Imperative Block like this:

pnt = Autodesk.Point.ByCoordinates;
lne = Autodesk.Line.ByStartPointEndPoint;

[Imperative]
{
    x = 1;
    start = pnt(0,0,0);
    end = pnt(x,x,x);
    line = lne(start,end);
    return = line;
};

1.3.3

1.3.3

New Functionality:

• Compatibility with Revit 2019

Known Issues:

• Some keyboard shortcuts do not work in Dynamo for Revit 2019.0. These include Ctrl+Z for Undo and Ctrl+C/Ctrl+V for Copy/Paste.

1.3.0

1.3

See http://dynamobim.org/dynamo-1-3-release/ for a full report

New Functionality

Core:

• Geometry Working Range, a solution that adjusts numerical precision to accommodate these large numbers.
• Isolate Selected Geometry
• A direct link to the Dynamo Dictionary is added at the bottom of help menu popup window for each node. Definitions are currently available for the out-of-the-box core Dynamo nodes, and we are actively working on Revit nodes.
• Multi-output port re-connect feature using Shift+Left-Click
• Highlight geometry from selection in preview bubbles and watch nodes.
• DateTime.Format: (shout out to Radu Gidei!)

Dynamo Studio:

• Translate (CAD import) functionality now supports 3DM (Rhino) and SAT file formats, in addition to DWG and DXF. (Additionally, import of FBX, OBJ, STL, and SKP formats are supported, but there is currently limited downstream capabilities with these meshes.)

Dynamo for Revit:

• Revit allows for duplicate parameter names in a file, and Dynamo is now able to consistently pick between Named or Built-In parameters.
• Preview Bubbles enabled for Revit Selection nodes
• New Revit nodes: a number of Creation methods for System Families, added access to Global Parameters, and exposed file auditing tools with the Performance Advisor.

Bug Fixes:

• Fixed line break issue in for group titles, increased group titles font size
• Convert between units now gives correct Hectares for Area conversion
• Fixed File Paths with spaces sometimes converting paths to escaped URI path
• Fixes to Arc.ByCenterPointRadiusAngle, Arc.StartAngle, and Arc.EndAngle
• Fixes to escape character (\) behavior and character escape sequences that are similar to C#: Now there are only certain characters that can be escaped and that qualify as valid syntax. All other character escape sequences are not valid and will result in syntax errors when used in strings in a code block node.

\' – single quote, needed for character literals 
\" – double quote, needed for string literals
\\ – backslash
\0 – Unicode character 0
\a – Alert 
\b – Backspace 
\f – Form feed 
\n – New line 
\r – Carriage return 
\t – Horizontal tab 
\v – Vertical quote 
\uxxxx – Unicode escape sequence for character with hex value xxxx

Other character escape sequences may have worked in 1.2 but they were really bugs as they were inconsistent with standard escape character rules.

String node is recommended for the purpose of using string literals as DesignScript doesn't have any native syntax for string literals.

1.2.1

1.2.1

Important Bug Fixes:

• Full Installation of Dynamo for Revit included in the Revit 2017.1 release will no longer remove Dynamo 1.x installations in previous versions of Revit. Dynamo for Revit 1.2 will now also be installed for any installation of Revit 2015 or 2016 as well.
• Dynamo for Revit is now included in Revit 2017.1 network deployments.
• Dynamo Player no longer takes all of 1 processor when launched.

1.2.0

1.2.0

New Functionality :

• New out-of-the-box Revit functionality, including FaceBased Family creation, Coordinates, Detail Curves, Dimensions, Filled Region, Filters, Location enhancements, Materials, Parameters, Revisions, Rooms, Tag, Text notes, and Element queries.
• New list management tools found on node input ports that can greatly simplify many workflows and reduce the need for List.Map and List.Combine in most places.
• Geometry Preview state of nodes shown in color change

Important Bug Fixes:

• 4 most common crashes identified through crash error reporting have been fixed. These failures were a combination of divide by zero and Null reference exception thrown from preview and some issues during initialization with Revit, which account for 30% of all reported crashes in Dynamo 1.1.
• Graphs with large vertex counts consume 1 processor when program is idle
• All Elements Of Category fails for Views
• Package Manager Crash and upload fixes
• Custom node can only place family instance(s) in isolation. Multiple use of same CN on graph results in 'last node wins'
• Number from Feet and Inches rounds input text incorrectly and output is confusing
• Circle.ByBestFitThroughPoints is always horizontal
• Preview Control Crash when deleting ObjectSelector node before running completed
• Crashes with adjacent install of some Autodesk products
• Solid By Sweep 2 Rails incorrect with rotated NURBS curve
• Opening dyn file whose dyn extension is missing corrupts Dynamo
• Arc.ByStartPointEndPointStartTangent doesn't work well with all Tangents
• Graphs with large vertex counts consume whole processor when program is idle
• CoordinateSystem Scale methods do not work
• Add option to Curve.ByBlendBetweenCurves to create G2 continuous blend curves

1.1.0

1.1.0

New Functionality :

• A whole new bunch of Library added for T-Spline Nodes. You can turn on this option from Settings to view the T-Spline nodes in Library. T-Splines modelling technology is now exposed in Dynamo to enable new organic and freeform geometry creation tools. There are approximately 150 new nodes that are a subset of the existing geometry library. Since this is an advanced functionality that may be useful only in certain non-standard workflows these nodes by default will be hidden in the library and will not interfere in node search results unless explicitly turned on in the Settings -> Experimental menu. The new functionality offers a wide range of capabilities to create and edit T-Spline surfaces and also conversion to and from NURBS and meshes.
• New notification center provides you with more details on system crashes and errors, such as when DLL incompatibilities between Dynamo and other Revit Addins are detected at startup
• New Settings menu option to Show or Hide Preview Bubbles
• We have fixed the long pending issue of Screen Capture, now it doesn't matter how big your graph is, everything will be visible at whatever zoom level you are at when you use Export Workspace as Image.

Important Bug Fixes:

• Element Binding (the ability of Dynamo to track and modify rather than duplicate or replace elements in Revit) had some regressions in Revit 2017. These are fixed.
• Freeze does not delete elements created in Revit anymore.
• Fixed issue related to FamilyInstance.SetRotation, now you can use this node with Run Automatic mode as well and your first instance won't get placed randomly in a different location and crash issues have been addressed
• Fixed long pending issue with Importing series of Swept Solids, Now while after importing all Surfaces are there.
• Localization crash fixes with Norwegian, German and French
• Dynamo for Revit no longer crashes at startup with non-compliant Views (not 3D)
• When selecting any labeled item only that item's label gets displayed, no additional labels are displayed
• Fixed errors on Code Block Nodes and String Nodes that are published to Web and accessed from the Customizer view
• Read-only nodes and directories can now be loaded in Dynamo.
• Mapping flatten nodes and flatten on single values no longer replaces data with null values
• Arc.ByStartPointEndPointStartTangent no longer fails using a normalised vector
• Direct Shape now recognizes material input properly
• /verysilent install of Dynamo for Revit now completes without user interaction
• Fixed crash with closed curve as input to Surface.ByLoft
• Dot product no longer returning erroneus scalars
• Zero radius and related bad geometry errors no longer create crash
• Turning off "Revit Background Preview" no longer turns off "Background Preview" on relaunch of Dynamo.

Other Changes:

• Now once you add a new path for Package location then all the packages from the new path will get loaded without relaunching Dynamo.
• We have improved the preview bubble for its Pin and hover over related issues.
• Updated the compact view of the preview bubble to display information about the number of items in an output list.
• Quick Access to "Getting Started" from Help menu
• From this release, we stopped migrating of 0.6.3 and 0.7.0 files. If your old files contain nodes from above two releases then you have to open those files on an earlier version (till 1.0.0) and the save them.

Known Issues:

• Installing Dynamo 4 Revit 1.1 Will require a reinstallation of Dynamo Studio with Studio 1.1 (1.0 and 1.1 cannot co-habitate). This issue will not happen in the future, when Future Dynamo Core installation will work with older versions of Products.
• Simplification of some overload methods will result in minor changes in behavior. Please see this document for specific nodes affected: https://github.com/DynamoDS/Dynamo/wiki/Dynamo-Node-Changes

1.0.0

1.0.0

• API Stabilization: 1.0.0 is a commitment to stable code that allows for smoother and more reliable movements from one version to another. To more clearly express this, we have been moving to “semantic versioning” to illustrate the nature of changes in each release. We will be using the fairly standard version naming with an x.y.z system, where x incrementing represents breaks to the API (requiring developer refactors), y indicates changes that are still backwards compatible, and z are smaller bug fixes. Package creators and maintainers are encouraged to assess changes to the previous code, which can be found here

  https://github.com/DynamoDS/Dynamo/wiki/Dynamo-Node-Changes

  https://github.com/DynamoDS/Dynamo/wiki/API-Changes

• Graphics performance enhancements: see this post for details
  https://github.com/DynamoDS/Dynamo/pull/6356

• Documentation: Along with new sections of the DynamoPrimer (http://DynamoPrimer.com), we have started an online documentation of the Dynamo API with a searchable index of public API calls for core functionality. This will be expanded to include regular nodes and Revit functionality. http://dynamods.github.io/DynamoAPI/

• Licensing: Dynamo Studio is now using a new version of the Autodesk installer that allows for easier access to network and token flex licensing tools

• Install: we have created a separate installation for "core" Dynamo functionality, those tools used by all implementations of Dynamo, and Revit, and Studio installations. This allows for the sharing of a common core of Dynamo code and packages.

• List Management: Changes to "replication" or automated matching of different data streams in nodes and Code Block nodes eliminates the need for List.Map and List.Combine in many situations

• Send to Web: formerly known as Share Workspace, we have improved the ability to view and interact with Dynamo online with Customizers

• File Export: Users can now author DWG files in the Translation section of Dynamo Studio.

• Direct Shape: Dynamo in Revit 2017 can now take advantage of faster and more sophisticated direct shape creation. In most cases, solid and surface geometry can be sent directly into the Revit environment as smooth (rather than tesselated) surfaces and solids, categorized to whatever is needed. In the cases where a smooth element cannot be created, a tesselated (mesh) object is created, as was the case previously.

Bug Fixes

• An extensive list can be found here: http://dynamobim.org/incoming-bug-fixes-for-dynamo-1-0-0

Known Issues

• Listed here: https://github.com/DynamoDS/Dynamo/wiki/Known-Issues

0.9.1

0.9.1

Dynamo Core

• Direct manipulation: Sometimes numerical manipulation isn’t the right approach. Now you can manually push and pull Point geometry when in navigating in the background 3d preview.
• Freeze Functionality: When you have long running portions of your graph, or don’t want to export data to other applications, or want to debug some logic, don’t unplug your nodes. Now you can suspend execution of specified nodes in the graph by using Freeze in the right-click contextual menu
• Search Enhancements: Only look at the node libraries you want to with new filtering tools. See more options at once by using a compact view, or get more information with the detail view.
• Zoom re-center: Select a node, then zoom and recenter your orbit on it in the 3d Preview Navigation
• CNtrl-drag: Copy/Paste nodes in a familiar way
• Add comments to custom node inputs and full default states for complex data types
• More forgiving DesignScript syntax: Users can now write instance methods (ex. MyCurve.PointAtParameter(0.5)) as Static Methods (ex. - Curve.PointAtParameter(MyCurve, 0.5))

Known issues

• No backwards compatibility with 0.9.0 and before. This is due to neccessary changes to the Dynamo API in advance of 1.0. These changes can be found in the API Changes document

• In some situations, placement of Adaptive components requires a change in list structure. The AC placement nodes now expect to receive lists of lists of placement coordinates. In the past, the nodes expected to only place one AC, now it expects to place many. If you are going to only place a single component, it needs to be nesting into a list.

• With Win10 the Dynamo Background Preview is blank. If your Win10 workstation contains a graphics card that used to work with Dynamo running Win7 or 8 and you experience an inability to render graphics you may wish to consult:

  https://github.com/helix-toolkit/helix-toolkit/issues/257#issuecomment-194145932

Dynamo Studio

• Share your work online: Share interactive parametric models online. Just publish your Dynamo graph and send a link to your colleagues or the whole world. People can view and interact with your designs in a regular web browser with no Dynamo installed
• ImportExport: Read directly from DWG files and only pull out those pieces of the file that you want.
• When a user downloads a dyn from the Customizer (or Shared Workspace), the dyn's Run setting is automatically set to "Manual". This may be confusing to some users when they open the dyn in Dynamo and see all Nulls in the outputs: simply click the Run button.
• Users have been reporting that the Customizer (Shared Workspaces) functionality is missing in Studio 0.9.1. If this is happening to you, please try uninstalling Studio 0.9.1 and reinstalling it. We are aware of the bug and a fix will be available soon. Please reach out to us if you experience any other related issues.

Dynamo for Revit

• Batch placement of adaptive components : Huge improvements to the speed and reliability of placing large numbers of adaptive components. Note that the nodes now expect lists of lists as inputs, so you may have to update your 9.0 graphs.

Fixes:

Namespace Collisions:

• Existing Code Block Nodes no longer affected by name collisions with functions that come from installed packages. For instance, Point.ByCoordinates in a Code Block Node was affected by a collision with a Point. operation in the popular Rhynamo package and would throw an error saying “Warning: Dereferencing a non-pointer. Dereferencing a non-pointer.”

Hardware Acceleration in Revit 2015

• Hardware Acceleration was turned off when running in Revit 2015. Graphic speed and clarity is greatly improved
