!HELP! Fail to create smooth pipe around helix

Hi, I tried to created a pipe around my helix, but it turned out like this… I tried to change the diameter of pipe but it still didn’t work. Can anyone kindly give me some suggestions?

How did you do that? I wouldn’t think you could make that without lofting or rail-sweeping curves.

Did you use create a spiral with the “spiral” command and then make a “pipe” around a helical curve? Perhaps one you could check with curvature graph, to make sure it’s nice and smooth, if you are tweaking the curve.

Are you running V5 SR9?
I’m guessing you need to get the current service release.

The last time I saw that was when my tolerance was set too low. When you pipe it, you can also look into the ‘global shape blending’ option; it usually defaults to local.
