In the attached file i have two closed curves. I try doing PIPE using 0.5" radius. For some reason the red curve creates the odd extensions at the corner.
What is that?
Oddly, when I copied this shape to a new file to upload here, creates pipe corners for a while then it suddenly started doing this.
Problem Pipe.3dm (3.0 MB)
Here is one where I have copied the curve to a fresh file. After I start playing with it a while it starts doing the extensions.
