Hi Michael,

I'm working on a pretty straightforward (to me at least) piece of mechanical design, but I keep encountering boolean issues - specifically "Unions" not working or creating strange overlapping surfaces. I'm attaching the most recent example - a trimming object I was trying to Union so I could use the unioned object in a later boolean difference operation.

I'm also attaching a screengrab of the trimming object in relation to the object to be trimmed - in case that helps...

Any sense of why the boolean op isn't working here?

Thanks - as always for the insight and assistance.
