Having trouble modelling a complicated curved surface based on stl file.

[Pahasave]

I have a 3d model of a tank turret that is in .skp format (sketchup) which I exported to stl, imported into f360 and converted to brep.

Yes there is a youtube video about creating the Fusion360 logo that I attempted to use but I keep running into errors (https://www.youtube.com/watch?v=XD7HBFlIFMM   Fusion360 was unable to repair the errors no matter how I tried. )

Either way it's too complicated for that method above as the turret has asymmetrical curves and lots of odd angles

I thought of using F360 instead of meshmixer because after creating the basic shape, I need to hollow it, create some parts for it.

a) Can you File -> Export and share your design

b) Can you create a STP / STEP file instead of the stl file? Might be easier to work with.

AFAIK sketchup only exports triangulated meshes. Even if it exports a .step file it might be a mesh.

Ouch - didn't knew that. Thx for pointing it out.

I can export it in dae or stl. that's all.

You said you converted it to brep, so export your Fusion 360 file instead of the Sketchup file.  Export it from the file menu: File|Export|Archive file *.f3d
