Mabat that is exactly what I spent a long time trying to reverse engineer from the mesh file, if you could release that it would be awesome.I can easily export the surface coordinates in a text file that can be imported as spilnes in Fusion 360 (I already have a custom add-on for that). Would that be useful? Is it possible to create a smooth surface and then a solid body from that?
I have attached zipped pdf guide of what I did to make a solid by thickening or by cutting a mould out of a block as before. I have tried to include all the steps to help someone who is not very familiar with Fusion 360.So I will make this available. I hope someone would then present a procedure that everyone can reproduce - I'm not experienced in CAD modeling. That would be great. What about some "guide" curves for this loft feature? I can export various curves of the surface.
It works either way, only meshes need to specifically have the design history turned off to work on.I turned off the timeline capture, not sure if needed.
I found that if I chose any more than 6mm for the thicken then fusion crashed.Job done. Now i got 6mm thick solid horn which i can further work with to add mounting holes, driver mounting flange etc.
Mabat, you are a hero!
Do you mean the original STL and the "lofted" one from the splines? That's what needs to be checked of course. The two might be slightly different, that's almost expected - that's where some perpendicular guide curves may help. I will let the user export those as well.The other thing I found was that the original surface and the thickened one were not exactly the same when overlaid.
I could export curve sets for two surfaces some (defined) distance apart if that would help.
