Hello Rynz, you never responded in your other thread, regarding how these pipes will be cut.
I guess it is pretty safe to assume that we aren't talking CNC here, as you are making paper templates.
I do fabrication drawings all the time of pipes and tubes with Autocad.
Yes Inventor (one or possibly both) has the capability to create the paper patterns, but my question is more along the lines of, do you need that to achieve your goal
of cutting these accurately enough to make this frame?
I am sure some Inventor users will jump in to help you, be patient, as the weekends tend to get a bit slow on the forum.
