following situation: 3D drawing in Inventor Professional 2010, consisting of lines and arches. How can I group respectively connect certain lines and arches so that these elements form one (3D-)polyline? Is that possible in general?
Thanks for your advice!
Language and terminology make it difficult to understand what you're asking. Are the lines and arcs in a part file (.ipt)? In more than one sketch? It sounds as if you want to create a 3D sketch from existing 2D sketches-- if so, then create a new 3D sketch and Project Geometry.
If I have misunderstood your question, please try again, perhaps with screen shots and the file(s) that you are working on.
If you are coming from an AutoCAD background - you don't use/need polylines like in AutoCAD.
Simply create 3D sketch using your 2D sketch as control with Bends.
Attach your ipt file here if you can't figure it out.
