Oh and for that line above, the #3 - you don't actually need to make it the line the exact same length as the arc as long as you don't enable the "Stretch" mode in the flow options.
When Stretch is off it will match "distance traveled along base curve" to the same distance traveled along the target curve, automatically extending if needed.
When Stretch is on it will match "percentage traveled along base curve" to the same percentage traveled along the target curve.
Looks like it can do also NURBS unfolded as NURBS when there are developable surfaces. So that might work ok (in pro version) for sheet metal models too. For polygon mesh objects it does Pepakura Designer type stuff with making tabs.
No it's the FormZfree that I have downloaded some few month ago maybe not latest version...
Latest is 10.1.5 (B27E) against mine 9.1.0 (Build A 399) ! :)
UI is falsely "friendly" ;) It's for that i did not yet made a page about it! :)
Multiple pannels to regulate... but some cool tools integrated... stairs, roof, terrain ... like SketchUp but without plugins!
Else in general More Subdive than Nurbs.... better than SketchUp without Plugins
Not so bad for the price! ;)
Can be a cool speed subdive protototyping for some things...
