Yep, works when I reload it.

It did have to do with those perpendicular line segments that touch the revolution axis.

The geometry library tries to replace those with a simple plane but it is all messed up. I've fixed this for the next beta.

Thanks for the bug report with the example file!

So another workaround aside from saving and reloading is to eliminate those line segments that are perpendicular to the axis, then after the revolve is done, select it and do Construct/Planar to cap off the ends.

You say "reload" : it's some constraining :)
This sort of problem can't be resolve by a simple "refresh" without exit of the program?

"reload" in this case doesn't mean exit the program - it means save the .3dm file to disk, and then load the .3dm file back in again.

But I've fixed this up so this won't be necessary in the next beta (except I just noticed I have to fix up my fix a little more...).
