Boolean Problems

Hey Michael,

I'm getting a frustrating boolean issue with a model I just started. I've attached the model and a screengrab to help describe the issue.

I'm trying to do a difference on the central object, removing the "vanes" highlighted in the screengrab from the central object. But every time I try, nothing happens - MoI doesn't even display the "calculating" flag on the dialog box at the top of the GUI . What am I doing wrong?

BTW - the central object was made from a revolved curve - not sure if that would impact what I'm trying to do.

Let me know if you need system specs or anything like that. Any and all help you can provide is greatly appreciated.
