Maximum Dimension Limits and Dimensional Resolution
Models should be drawn in the dimensional range described below. The resolutions are limited as well.
Drawable Range (Maximum Dimension)
The drawable range is limited to the absolute X/Y/Z coordinates of (-500[m], -500[m], -500[m]) to (500[m], 500[m], 500[m]). It is a cube of 1000[m] x 1000[m] x 1000[m].
Any operation beyond this range is invalid.
If the unit is [um], however, the range is
(-500[um], -500[um], -500[um]) to (500[um], 500[um], 500[um]).
It is a cube of 1000[um] x 1000[um] x 1000[um].
Dimensional Resolutions
The minimum drawable dimension is 1.0e-8[m].
Any length, radius or distance shorter than this is considered nil.
All the coordinates that differ within the resolution are considered same.
If the unit is [um], the minimum drawable dimension is 1.0e-8[um].
See the list below for the details.
Angular Resolutions
The minimum angular resolution is 1.0e-11[rad] = 5.7e-10[deg].
Any angle smaller than this is considered nil.
The Units and the Limits
The limits vary depending on the units,
as summarized below.

1.0e-8 [μm] |
1.0e-11[rad] |
* If the size is larger than the dimensional resolution but close to it, modeling and meshing may fail.
The dimensions more than ten times the listed values are recommended.
