Tube along spline curve
Tube along spline curve
(OP)
Hi,
When I make a tube along a spline I can not measure the diameter or use the concentric assembly constraint on it. Even when I have a straight line at the end. Why??
Regards, Michel

I also tried the infer axis method, but did not work either.

I found out that when you have a straight end and put an extra extrude on that it doesn't work anymore. But why?
See attached file. Not all circular ends are selectable with concentric constraint.

This flange has for some reason become a little ..., i.e the outer edge that one would expect to be circular is a "tolerant curve".
A tolerant curve is a "anyshape-curve", spline etc and therefore doesn't respond when NX searches for arcs/ellipses.
I would assume that it is due to that the extrude 8 is made from the inner edge of the tube, which is an "intersection curve", then the outer edge becomes this tolerant curve instead of circular.

Tomas
