Boolean Operation - 2 Parts w/Substrat

Hello All

I cannot seem to remove what is left from the Boolean operation of a tube joining another tube at 90 degrees, see the sketch.

I want to remove whats left in the notched-hole; but when I delete, the tube goes along with it.  So gents, what's up?

    Are you using the Delete Part feature?

    Are they actually two separate parts?  If not when you delete one you delete it all. :/

    If that is the case then you might be able to make that "lump" go away by using the "delete face" feature but instead of that I'd probably chose to:-
    (a) Use the "Transform Copy in place" feature to copy the tube you used as a boolean removal tool.
    (b) Delete the inner face of this tube copy, thus turning it into a solid cylinder.
    (c) Boolean this new solid cylinder away from your target part.

    If you post a link to your document it'll be easier to debug.  Details here on that process :- https://forum.onshape.com/discussion/9107/forum-post-checklist-read-this-first

    Neil - seems after the Boolean Subtract Operation; the useless parts are duplicated in the "parts list" with the same part designation as the original.

    It is an extra step(s) to hunt-and-peck for the 2-4 similar part names to delete them.  However, your suggestion produces the desired results, thanks.

    Problem Solved.

    If you post a link to your document (instructions here: https://forum.onshape.com/discussion/9107/forum-post-checklist-read-this-first ) we can take a more holistic look at the document and see if the issue can be fixed be editing an earlier feature, rather than just tacking more features on the end of the parts list.
