Loft and sweep trouble from imported dwg lines


New member
I am a new Rhino v4.0 user and I am having trouble with the loft and sweep tools with imported lines from AutoCAD dwg. The rhino tools only work for each line segment. I would like for the tool to work for the entire line. Is there a Rhino tool that can tell the loft or sweep tool to treat it as the entire line?
Thanks, Mitch

looks like you have DXF segmented curves, try rebuildcurve on them or trace over them to make them splines.


Rhino works with NURBS curves. The DXF line segments are not really NURBS. Therefore you cannot loft or sweep the entire length.
