MESH to Solid Prismatic conversion results in an incomplete solid

[donmuttlyward]

Hi all, I'm having issues trying to convert a number of STLs to solid and have recently upgraded to the commercial license to access the Prismatic option. This was done so that I don't have to faff around with deleting the many many triangles in the obj.

I've followed the following guidance https://www.youtube.com/watch?v=tVGtG-UjlYg&t=74s but no matter what technique I use, I end up with models with missing faces or incomplete solids as per the attached image. I'm a hobbyist and have no other training so I don't know where I'm going wrong but happy to be told how to fix this by those that are experienced.

Mesh to BRep is not a viable modeling workflow. It often fails, specially with low quality mesh or ones with blended fillets. This STL qualifies for both criteria:

And as such I wouldn't try to convert this, but remodel it using Fusion's native tools.

Ok that's dissapointing and I may have wasted money on the upgraded version. As you can see it's a complex shape and I don't possess the skills to recreate it or have the time needed to get to the desired level of competence. Is there no way that I can change the model and edit holes etc? If I do the standard faceted conversion it does give me a solid object though I have to delete many facets to clean it up but then it still looks ugly.

This object is not really a complex one, at least not in regards to the type of operations needed for modeling it. As far as I can see it can be created using only the most basic solid operations (Extrude, Fillet, Chamfer, Shell). Yes, it needs quite a few of these operations, with proper sketches, but no complex tool is required. I say if you have basic training in solid modeling in Fusion you'll be able to do this in less than a day.

Also forget about faceted conversion, it's not something to work with afterwards.
