Trouble making a single edge after subtracting a mesh body from a block.

[Anonymous]

I'm trying to fillet a body's edge that is made up of hundreds of triangles.  The body was produced by cutting a mesh that had been converted to a body from a cube, so while the remaining object is not a 'mesh', some of its surface appears as a network of triangular surfaces.  Where the mesh body intersected with cube's outer edge, there is an 'organic' edge made of many small segments - each from a triangle.  I believe i need to make a single edge to be able to fillet that edge.  Any advice would be appreciated.  I'm very new to the software.

Yes - thank you for posting how to get the .f3d file! I'll add momentarily.

What does the original geometry look like?

Why is it low-quality mesh?

The original mesh looks like a shoe and has something like 200,000 triangles.  I reduced the size of the mesh using Fusion to under 50k, converted to a body, then put a box on the toe and subtracted the shoe from the box.  The quality or resolution is plenty for what i need the part to do, but i need to uniformly bevel or fillet the u-shaped edge on the 'left' face.

I am pretty sure I would not have done that.

yes - i saw other options in the forum involving multiple pieces of software to decrease the size and bring it into fusion, but since the resolution i needed was fairly low, and I'm new to all of the software, I did it this way.  Is there another way that eliminates the issue I'm having?

Solution was to turn off the capture of design history, select small sections of triangles (limited probably by my lack of computing power), and Merge those triangles in the Surface tab.
