LDPartEditor 1.8.89

Changes:
With the release of 1.8.89 the following critical issues are fixed:

1. Descriptions containing a hashtag # are modified by unrelated quick fixes.
2. The movement type of the manipulator changes if, during the move, the mouse gets close enough to a plane move square.
3. The CSG tree does not switch back to a higher quality if the manipulator was moved and nothing CSG releated was selected.
4. The MacOS X ARM installer package was still indicating a 1.8.80 version, but the contents were newer.

Installation

Windows

1. Download and run LDPartEditor-1.8.89.msi
2. Start LDPartEditor from the start menu

When you install LDPE on Windows you will find your LDPE configuration files under
drive\Users\username\AppData\Roaming\LDPartEditor.

LDPE is a 3D CAD application: The overall system requirements are higher. While I recommend to use a powerful 64-bit multicore system, it could be possible, to run LDPE on older machines as well.

System Requirements:

Minimum System Requirements:

• OpenGL 2.1 compatible Graphics Card
• Operating System (64-bit): Windows [7 or newer], Linux [e.g. Ubuntu Linux >=14.4], Mac OS X [>=10.6]
• CPU: Multicore-Processor e.g. Intel Core 2 Duo or AMD Athlon II (>2.0Ghz)
• RAM: 4GB
• Video-Memory: 1 GB
• Free Disk Space: 150 MB

Recommended Requirements:

• Operating System (64bit): Windows 7,8,10,11, Linux [e.g. Ubuntu Linux >=14.4], Mac OS X [>=10.6]
• OpenGL 3.3 compatible Graphics Card
• CPU: Multicore-Processor with 4 cores (or more)
• RAM: >4 GB
• Video-Memory: >1 GB
• Free Disk Space: 500 MB
• For a faster start, the LDraw™ library should be installed on a SSD.

PS: I am still busy with the creation of the manual, so you "have to experiment" with my (complex) software product until you've got the manual.

LDPartEditor 1.8.88

Changes:
With the release of 1.8.88 you are able to...

• ...double click on a text editor error/warning/hint to also select the object in the 3D editor.

The following critical issues are fixed:

1. Primitive substitution on subfiles from PartReview causes subfiles to be "empty".
2. "Rings and Cones" uses old deprecated "rin" and "ri" ring primitives.
3. The context menu entries on the error/warning/hint area are always enabled.
4. After loading a part using the part review tool, the 3D view properly shows the part asked for, but the text window generally shows a subpart of it, presumably the last loaded one.

Installation

Windows

1. Download and run LDPartEditor-1.8.88.msi
2. Start LDPartEditor from the start menu

Linux

1. Download and install ldparteditor_1.8.88-1_amd64.deb

LDPartEditor 1.8.86

Changes:
With the release of 1.8.86 you are able to...

• ...use the sphere mesh from LDView for CSG operations, too (!LPE CSG_ELLIPSOID).
