Issues with Split Body Tool

[colemanHEXZG]

Hey there! I'm trying to split this body into two parts because I am having to pull out the front face by 1mm and that was the easiest way I could think to do it was to split and then loft the two bodies together. I keep getting issues with not having any intersection between the plane and the body.

That is not unusual with mesh-based solids or, more precisely, with solids created by directly converting a triangulated mesh into a solid.

Converting a mesh directly into a solid is one of the worst workflows I can think of, and that should never have been implemented.

Due to the high facet count and very high aspect ratio of the triangles, near-coincidence situations often cause these problems.

Moving a split plane slightly, even by 0.01mm, can sometimes help. Experimentation is a good idea.

Doing this was the best way I could think of symmetrizing the body. This geometry came from a mesh originally and Meshing and reducing factets was the best way I could think of fixing the body. Is there a better workflow to go through?

Can you post the original mesh ?

Zip it before attaching it.

The object is relatively simple, so I would use that original mesh to  recreate the object from scratch using the native tools  in Fusion.

Hi! I could be wrong but I just don't see a good workflow to edit the faceted body as is in Fusion. The body was probably converted from a mesh. The mesh should be repaired  and simplified in the Mesh Design environment before being converted back to a smooth body, not as faceted body.

As a precise modeler, Fusion has to track and tag each piece of geometry on the body. These edges and faces on this mesh-converted body do not represent any design intent. They provide unnecessary detail making any modeling operation more difficult. Please import the mesh to Fusion Mesh Design environment.  Repair and simplify the mesh so that the mesh becomes watertight. Then convert it to an organic body.

Many thanks!
