Attached two sweep2rail surfaces, their junction is from a rail used for both sweeps.
As such the surfaces abutting there should be identical yet mergeSrf wont join the surfaces. I have this throughout the entire object made of rails all parallel as these are.
I also tried Join as well, fails.
Boolean Union works.
why the differences and is it ok with Boolean or wil some commands fail on it ?
