qball Posted August 17, 2009 Share Posted August 17, 2009 I created a contour of an area using 3dpolylines and lofting them. Then I created a surface plane and I wanted to use the surface to SLICE the contour. But when it says "Select objects to slice" I pick the contour it says "No solids selected". Is there another command? I thought it would be so simple, but apparently not. Is it because the polylines weren't closed that it never actually created a solid? Do I have another option? new block.dwg Quote Link to comment Share on other sites More sharing options...
Secretagdan Posted August 18, 2009 Share Posted August 18, 2009 When you list it, it calls it 'LOFTEDSURFACE'. To slice something I beleive that it would need to be a 3D solid, which would be why you can't slice it. Quote Link to comment Share on other sites More sharing options...
maxerr Posted August 19, 2009 Share Posted August 19, 2009 ok, is there a way to get the 3d polylines or polyfaces to become solids? Quote Link to comment Share on other sites More sharing options...
qball Posted August 19, 2009 Author Share Posted August 19, 2009 I tried to redraw them as a closed 3d polyline and when LOFT-ing it, it said "first and last must be coplanar".....?? oh well. Quote Link to comment Share on other sites More sharing options...
scj Posted August 20, 2009 Share Posted August 20, 2009 Use the THICKEN-command to make a 3DSOLID from the surface (be care to take a very small thickness as the 3DSOLID otherwise can get self-intersections). Furthermore I had problems to use the SLICE-command. So I made a BOX from the cutting plane and used the SUBTRACT-command to cut the 3DSOLID. I have problems to upload the result (> 2MB). In case of interest contact me personally via scj.schulz(at)t-online.de regards Jochen http://www.black-cad.de Quote Link to comment Share on other sites More sharing options...
qball Posted August 20, 2009 Author Share Posted August 20, 2009 THICKEN didn't work for my application, but making the 3d solid and subtracting did work. You are wise SCJ, well done. Quote Link to comment Share on other sites More sharing options...
