*3DP-PLANE-RECOGNITION-ENABLED* [Public Variable]
Package: 3d-printing (Nick name(s): :3dp)
Plane recognition option default. Can be customized in 3dp_customize.lsp.
If set to T the plane recognition component attempts to find best-fit planar
regions for sets of contiguous mesh triangles with a given approximation accuracy.
The planar regions are then converted into planar model faces to
reduce model complexity.
Specify NIL to turn off recognition of planar faces by default.
