I want to weld the parts of a bicycle frame, but what ever method I used, when I “union” two solid polysurfaces the horizontal one is no more a tube.
Cut of diagonal and horizontal tubes by direction tube
Boolean Split at 0.00:14
Union at 0.00:35
Still 3 tubes welded as one solid polysurface, OK.
Then I want to cut and weld to seat tube.
Boolean Split at 0.00:49
Union at 0.01:10
Zoom at 0.01:21 show that horizontal tube is no more a tube.
I presume that it is a bug.
I waste time to find another method to avoid it, without success, could you help me on that ?
