How would I sculpt or fillet these edges?

Hello,

My current project requires editing a corner of a mesh that's been converted already, however, since there are countless triangles, I cannot simply select and use fillet to round. I will leave attached a picture for reference!

Please share the model by exporting it as a.f3d file and attaching it to a post.

Judging by the screenshots, the model suffers from  geometry problems, and it isn't a surprise that filleting fails 😉

Hello,

Thanks! and yes that is the problem. However I cannot rebuild it! New question though, how can I connect these?

Please share the design in .f3d format.

Generally speaking when dealing with geometry that its basically a prismatic (mechanical?) object, but is represented as a triangulated mesh, usually the best way forward is to redesign this from scratch using the native tools in Fusion.
