flatten 3d wire frame arcs when not parrallel to z plane

[pahuntr]

I have a 3D wire frame that has arcs that are not parrallel to the z plane. Using the lisp program "flatten" projects the arcs to a new z depth but normal to the plane they were drawn on. These arcs are actually ellipses when viewed normal the the z plane. Does anyone know of a way to project these arcs normal to the z plane to z of zero?

Try plotting to a DXB file.

See this link below. :mrgreen:

Another option would be to use the "solprof" command in LAYOUT (paper space).
This should automatically trace the wireframe model to a 2D format.

Hope one of those ... works for ya'

Later. :D
