I’m looking for some help or pointers as I have no-one to ask and I’ve reached a dead end. I’ve searched here and elsewhere and not found any good threads, apologies if I’m asking a common question.
CAD user new to Rhino and this type of work.
I am trying to make various wings, both a solid then making Molds based on the wing solid.
My approach as been to create solid:
- Clean up incoming profiles manually
-check, close Trailing Edge gap to a single point
Not sure if I should be using any particular Rhino commands here to make uniform/smooth etc?
- Create rib sections along the wing shape, scale appropriate profiles to fit planform
- Loft bottom surface using rebuild to x control points or refit to tolerance.
Starting with bottom surface, loft from a line at wing tip to first profile (rib) then on to end (root).
Sometimes this is done in sections, then sections joined after MatchSrf
Repeat for top surface
- Mirror, Join
Then Create Mold, then subtract using Boolean operation.
Boolean Subtract is failing even though both the wing solid and the mold solid are “closed polysurfaces” which test ok, have volume, no naked or manifold edges.
Could the Boolean be failing because of having a sharp trailing edge?
Are there some other commands I could try?
Is there a better approach to building a wing & Molds? I have played with using closed curve profiles instead, but it seems to make the Loft much more problematic.
Any advice, links, commands, tips would be much appreciated.
PS I will post this then try to append and example file.
