I’m saving my pennies for a Proliner. Using a Disto 3D right now which works, but is a tedious process.
My first lesson converting my captured dxf to Rhino is to add extra for your first covers. My first few were always to small… you can take away if too big, but not really add on if too small.
Use “squish” with CompressMostly or CompressOnly. This is 2D --> 3D relationship. So this makes the flattened panel slightly larger. Don’t use Smash for curved panels.
if you have multiple hard curves, cut a line though them, loft, or NetworkSrf each, then Surface Merge them on the 3D object then flatten. If you try to loft or NetworkSrc complex areas at once, it’ll come out wrong.
Try Loft, NetworkSrc, Sweeps. Each will work better then the other in some situations.
Then there’s the Mesh stuff that Pascal talks about… I’m lost there on that but need to learn more.
That’s my level 2 amateur tips. (=
