Hi Bob, could you post an SAT out from Alibre? Maybe that will be a better way.

The step file is a mess in Rhino8 as well.

Here's a SAT zip. The Gods are against me, even the Zip files not wanting to convert properly!

Hi Bob, are there any options for Alibre's SAT export? If so can you show me the options dialog for it?

Is the piece with fins one solid in Alibre or a bunch of separate surfaces? It seems to be surfaces in the SAT file.

Is that SAT file from Alibre or MoI?

Its made with the harmony ware translator. I wasn't aware that Alibre used that library...

Since Alibre is Acis based, the best export out should be the SAT format, from Alibre.....

Hi Bob, here's a version with things tuned up to be solids:

There were several areas that had some teeny tiny micro edges, those can get in the way of joining. So I needed to reconstruct some places around those.
