Boolean Operation
The following page lists all boolean operations available with the 3D Texture tool. The boolean operation is executed between the support and the pattern.
Note:
- You cannot set tangent surfaces between patterns and a support. A gap is needed and must be larger or
equal to ten times the Geometrical Distance Tolerance.
- You cannot set tangent surfaces between patterns. A gap is needed and must be larger or equal to ten times the Geometrical Distance Tolerance.
- Patterns cannot intersect.

Note: Set the Geometrical
Distance Tolerance to G / 100 in the assembly preferences (ex: if G=1e-5 then Geometrical Distance Tolerance=1e-7). This gives
fewer errors in the propagation of the photons. Also note that the texture width cannot be
larger than the material width.
