To the problem.
I have a tube where I wish to draw another tube in a 90 angle to the surface
I have seen the tutorial gif here: Holes in cylinders
The tube I wish to intersect with the other tube should be 500 mm and I start measuring a guide in a distance of 500 mm from the other tube. When I make the first circle, it ends up in a crooked angle. See attachment.
I have spend all evening trying to solve it with no actual luck. I am not happy having to go to bed without a solution What am I not doing right here?
