Hopefully this will be an easy question.

I'm working on a 3D drawing that has tubing intersections in various
places.  For the most part I draw the tubes around centerlines and
dimensional laid out per specs, but the result of a lot of
intersections of these lines is short tubing pieces that extend just
beyond the tubes they intersect.  Is there a way to trim this excess
tubing off of the picture?  I've looked at the TRIM command, but it
only seems to work in 2D (unless I'm missing something).

Suggestion are appreciated, thanks.

Unfortunately, what you seem to have found seems to be true. The trim
command works only with curves (whether in 2D or 3D) but not with
surfaces or solids..

All 3D examples shown in Trim help do not trim solids but only edges
of solids which are curves.

I have explored various other solid related commands and their
combinations but it does not seem to be possible. Just a reminder that
AutoCAD is not a full fledged solid modeler.

Turn off delobj (DELOBJ 0), or just duplicate the major tubesm then
SUBTRACT the duplicates from the minor tubes
