log command error and/or split surfaces

[poldo]

Imagine 3 tubes starting from different points (at 120°) and join in one tube.
Kind of like the highway entrance lanes.
the diameter of the tube is constant always, both in all 3 tubes and from the beginning to the end of each tube.
in the last stretch they overlap obviously.

I used the seep1rail command.
I can't delete 2 of the 3 overlapping surfaces in the last stretch.

If the diameters were different, I would keep the diameter greater and with the command "tronca" or "southdivid" I would eliminate the missing parts.

But it makes me mistake, how can I do it?

I think you can't erase them because it created you a single tube surface

if you want to combine them with the intersection curves, use those to trim the various surfaces and then reunite the whole

 

[poldo]

mmm, and how do you get the intersection curves?
It is not a sort of deformed circle because the diameters of the pipes are identical.
If I found the intersection curve, it would not be closed

the command to obtain intersection curves between 2 surfaces is _intersect.

I suggest you process 2 tubes at a time, not all together. :smile:

you should get the one shown in the image and contained in the attached file
