Mesh boolean union problem

[martinsiegrist]

Dear developers, here’s a file with two mesh parts I client created / modified in Blender.

The two meshes don’t boolean union in Rhino 8 WIP but do so instantly in Rhino 7.

I just tried a MeshBooleanUnion in the V8 WIP and it worked fine.

Did you use BooleanUnion or MeshBooleanUnion in the WIP?

Are you running the current WIP?

[martinsiegrist]

Thanks for your reply @John_Brock I tried this yesterday with the latest build and today again after updating and it does not work. I used MeshBooleanUnion.

It doesn’t look like you’re actually running the command.

1. Start the command
2. Select both meshes
3. Press Enter

[martinsiegrist]

That does not change anything. Preselect or not it fails.

My units in Rhino 8 WIP:

I copy pasted the two objects to Rhino 7 and hit the command and the two meshes are unioned.

Interesting…
I just updated to a newer WIP and it fails for me now too.

I’ll get it on the pile.

[martinsiegrist]

Thanks

[John_Brock]

I’ve isolated when the change went into the WIP that broke this case, and added a defect report for the developer.

Thanks for the report and sample file.
