Placing blocks

Editor

The block placement editor consists of three frames.

• Frame1: Cross-section viewed from above (Y-axis direction)
• Frame2: Cross-section viewed from the side (Z-axis direction)
• Frame3: Cross-section viewed from the front (X-axis direction)

• The intersection of the horizontal and vertical guidelines (blue double lines) is the current cursor position. The cursor in each frame all points to the same block position.
• The frame with the orange border is the active frame.

Keyboard operation

Block placement operations are done using the keyboard.

Key	Function
→	Move the cursor to the right on the active frame
←	Move the cursor to the left on the active frame
↑	Move the cursor up on the active frame
↓	Move the cursor down on the active frame
Page Up	Move the cross-section of the active frame forward
Page Down	Move the cross-section of the active frame backward
Space	Place a block at the cursor position. You can place blocks continuously by moving the cursor while holding down the space key
Z	Zoom in on the active frame's image
X	Zoom out on the active frame's image
Tab	Change the active frame
0-9	Switch the block to be placed. Numbers 0-9 are assigned in order from the left of the block list.
F1	Starts figure mode in rectangular mode, or changes to rectangular mode.
F2	Starts figure mode in rectangular surface mode, or changes to rectangular surface mode.
F3	Starts figure mode in ellipsoid mode, or changes to ellipsoid mode.
F4	Starts figure mode in ellipsoid surface mode, or changes to ellipsoid surface mode.
Enter	Fix the figure mode area.
Escape	Cancel figure mode.

Figure mode operation

It is possible to place blocks on simple shapes such as cubes and ellipsoids.

Figure mode	Key	Description
Rectangular mode	F1	Fill the interior of the specified rectangle with the specified block.
Rectangular surface mode	F2	Place blocks on the surface of the specified rectangle.
Ellipsoid mode	F3	Fill the interior of the ellipsoid inscribed within the specified rectangle with the specified block.
Ellipsoid surface mode	F4	Place blocks on the surface of the ellipsoid inscribed within the specified rectangle.

To place blocks in simple shapes like a cube or an ellipsoid, follow these steps:

1. Move the cursor to the starting point of the area to be specified.
2. Press F1-F4 to start the figure mode.
3. Move the cursor to the end point of the area to be specified. (At this time, the rectangular area will be filled and displayed.)
4. Press Enter to confirm the area. (At this point, the blocks are not yet placed.)
5. You can now move the cursor to see where the blocks will be placed.
6. Press Space to place the blocks. The blocks placed will be the one selected in the block list.

Note Before pressing the Space key to place the blocks, you can:

• Press Escape to exit the figure mode.
• Press F1-F4 to change the type of shape to be placed.
