Note: The settings in this block should not be changed.

Settings

action: Type or Run to be selected. Offset=Surfaces will offset if thickness value exists. No-offset=all the surface/solids will be read, no offset applied and converted to HM format by assigning PID, Material and Thickness; Supported values: offset, no-offset. Offset is recommended.
