I have problem while working with loft command.
I have defined shape and managed to place 3dpolyline in edges of shape (shape is rectangle, and 3dpline is spiral-helix with done segmentation) ...
While trying to do loft command, AutoCAD 2008 tells invalid guides, or can't complete operation...
If done with only one guide, or used loft with direction curve it does job, but result is the same as doing extrude-path...(while trying to preserve twisting shape along path)
If done with helix as guides, it finishes OK. (4 helix as guides, rectangle as shape - result : non twisted solid is made)
Why are 3dplines invalid objects for this operation, this is also for splines in 3D?
I prefer working with 3dplines or splines in 3D, can this be solved?
Also, when I try to do union (solid element operations) with lofted objects selected, operation can't be finished, why? (probably too complex objects are selected?)
Can extrude by path be done without twisting shape along path, or this must be done with loft command?
