Hi Michael,

thank you for reply. You are right that this way of unfold objects is reasonable only for specific structures. Practically for simple models with parallel side walls, which is modelled with specific rule.



I've modelled next test objects and unfold them in AutoPOL (http://www.autopol.com/products/unfolder/introduction/introduction.asp?sidebar=intro_u)
Left object was modelled by loft command, object on right is modelled via extrusion and union.



imported DXF from AutoPOL - 3dm, attached



I wanted to see the difference of unfolding process, detail of bended part of models is here:



Of course I would obtain same results by copy of outer surface of model - rotate axis of separated faces, calculate length of radius, joint together and export DXF.



Question is, if it's possible to write script which can do this operation automatically. Length of radius should be let as variable which take into account material and tooling.

MoI is excellent CAD modeller and construction program and this utility would help a lot for metal sheet parts, which is quite often part of more complex assemblies.

Maybe such scripts will be nice exercise for some experts from this amazing forum.

Here is the test of Cloth script written by Max Smirnov, for instance :-) http://moi3d.com/gallery/viewitem.php?id=790
