One last question Michael,

>Then I built the longer sweep part, and the donut sweep part, then selected them both and used Edit/Trim to cut them with each other. Then Edit/Join to glue them together.>

When I try this I have to do:

Select long object, trim with doughnut.

Boolean union.

Join.

I cant get it to become 1 with just trim and join as you described.

Am I missing something here?

Thanks again,
Burr
