Modifying a mesh thats been converted to a solid

[JayDee456]

Hi All,

I have an STL file that I received from a friend (attached), which is a triangular mesh..

I understand its difficult to work with triangular meshes in Fusion...I've tried converting to quads using Instantmesh, I've tried working on it in other programs, but I either lose quality or still have the same issue of not being able to chamfer some edges!

What I have done is... I imported the triangular mesh STL file into Fusion and converted to solid body. It's easy enough to then to add parts on and modify them etc. I'm fine with that. My issue comes when I try and chamfer the hexagon holes that pass through the body. I want to put a 1mm chamfer on all edges on both sides of the body but no matter what I do I cannot get it right. I assume it has something to do with the mesh or the curvature of the body, but I'm not sure.

Any assistance here will be appreciated!

Thanks!

Well, it is possible to do this, but you won't like the workflow😀

Open the Surface workspace.
Patch the outer rim of one of the hexagons.
Extend all of the sides of the first patch 1mm by selecting each segment before opening the Extend tool.
Copy/paste and move this patch 1mm into the body.
Offset each face of the hexagon 0mm.
Split Body with the target being the hexagon offsets and the splitting tool, the second patch.
Hide the 1mm section of the hexagon offsets.
Surface loft between the hexagon and the first patch.
Boundary fill this.
Combine/Cut this from the grip.
Repeat 131 times.

Hi ETFrench, thanks for the solution. I've given it a try and it will be a nightmare to try and get all of the hexagons chamfered!

Do you perhaps have a simple method to fill them up completely instead? I assume it will be using the patch and then extrude on each one, but I'm not sure how to get the fill to match the contours of each side.

Thanks for the assistance!
