Turns one body of an imported CAD part into a Solid, so it combines with every other Solid operation. The field is the distance to the body's tessellated surface: a closed body is a solid, negative inside. A surface saved as STEP is no body but a CAD Face, which counts as the half-space on the side opposite its normals wherever a Solid is taken — by itself, or through this block: the same open sheet, which Cut or Intersect takes a side of and Thicken Surface gives a thickness.
How closely the Solid follows the CAD surface, in mm. This value sets the tessellation: asking for finer than the import produced re-tessellates the part at this accuracy.
Values the block gives besides its output. The editor lists them under Properties, and an input can read one by reference.
The axis-aligned extent of the Solid.
The Solid's signed distance, as a field.
The Solid turned inside out: what was inside is now outside.
