hi,
thaks, but im using IntelliCAD engine (ProgeCAD release), this commands are not contemplated.
I think the best solution for me is through a lsp program.
With apl.lsp (found on http://www.cadtutor.net/forum/archive/index.php/t-50376.html )
is possible to find half solution for a correct and intermediate UCS, but cannot draw directly intersection line.

Hello,
I'm a new member to your forum, I have a question.
Is possible to make a short Lsp with to draw a line that represents the intersection of two 3DFACE (not coplanar).
Basically I would digitize three vertices of first 3DFACE and then the three vertices of a second 3DFACE, lsp procedure should draw the line of intersection.

Many thanks

screenshot:
white = 2 3dface not complanar
blue = intersection line
green = maximal projection of 3dfaces on intersection line
