Also there's a bit of a problem in the "seam" area where the knurls close up - if you do a highlight naked edges (the script mentioned here: http://moi3d.com/forum/index.php?webtag=MOI&msg=4869.5 ) you'll see that there is a line of naked edges running down the "seam edge" of the cylinder area.

That can probably be repaired by doing a Join but Join won't work on just one single object piece, you need to separate out at least just one little face from the current object, then select that little face and the whole other part and then do Join and it should then get that seam area glued up.

Was this created from using Flow? There probably needs to be a tune-up to Flow to join these things up when opposite sides of the original object end up touching one another in the flow result.


Once you do that "separate one face and then join it back", to get the seam joined, then you can use Construct > Planar on it to make the knurl thing into a solid with capped ends.
