I'm having issues meshing a single part. Its a tube frame chassis for an FSAE car, for reference it looks like this:

I get a warning that says the "Mesh information is not current. Model might have been updated or mesh element size/tolerance was modified". I have tried to remesh, but this dialogue box:

that usually opens when I hit create mesh doesn't open. Instead it immediately begins to create the mesh, which looks like this:

I have tried remaking the model from scratch, and I got the same error. I tried making a very simple part (a rectangular 1/4" plate of steel) and it meshed just fine, and the dialogue box I mentioned above opened when I hit create mesh. I have no idea what to do, do any of you?
