Boolean failed (looking for precision)

  1. Draw 2 circles, equal and tangent each one
  2. Apply “Pipe” to the circles
  3. Apply “Boolean Intersection” -> it fails.

If the 2nd circle is moved (by Gumball) of 0.001 the boolean operation works fine.

Question: is there a way to do a boolean intersection (or other bool operation), without move the circle?

Hi Gilbert - most likely the seam on the pipes in on the top of both objects in your example - if you move the seam (SrfSeam command) to the quad that is away from the intersection - actually anywhere may do but I’d move it all the way out from the ‘operation’ you intend - then Intersect makes clean curves and the Boolean will work.

FInding clean intersections where surfaces come tangent to one another and edges coincide is an ongoing project…

Pascal THANK YOU very much! It works good!

@pascal what if instead of close circles there are 2 arcs, each one tangent to the other? (imagine one 90° arc, mirrored and copy to its end, forming a “V”)
