I’m confused why I can’t separate the connector at the end of the board from the board itself. When I created the connector, I chose “New Body” and it even shows it as a new body. What am I missing?

Hi Jeremy,  
It looks like the problem happens with Extrusion 04. (I could see this by putting a breakpoint after Extrusion 03, and it was a new body as expected.)

But, Extrusion 04 is the little front piece of the connector, which you have set to Union. I believe it should have only union-ed to the connector and not joined the PCB with it.

Looks like a bug to me.

Hey Bob…yeah, that is what I expected it to do. I figured if the main body of the connector was already a new body, anything added/changed on it would not be a part of the board either. I ended up just extruding the board in the opposite direction until it disappeared and then just made a new board.
