This is a problem I’ve been wondering about for a while. I’m currently modeling handrails to be sent to a fabricator. Due to complications in the pipe function (the curve being piped is doubly curved at certain moments and has numerous changes of direction) and Boolean Union’s occasional unreliability I was forced to combine two intersecting objects by Boolean Splitting them by an arbitrary cut plane running through each object and then Boolean Union’ing them. You’ll notice in my photo that the isocurves in the pipe don’t align. I know for a fact that the surfaces in question are perfectly aligned and continuous such that they could simply be one surface. Is there any way to get rid of this unneeded seam edge? It is distracting and sometimes unclear. In this particular case the geometry will work fine regardless of the seam but there have been occasions where such seams cause problems for me. I know that it is possible to merge two continuous, intersecting planar surfaces so that the they don’t show anymore.
I’m essentially looking for the equivalent of “MergeAllFaces” but for developable curved surfaces. Thanks.
