Hi Alex,

re:

Can you please post the .3dm file that has this series of arcs in it?

If you can also post the DXF output from SolidWorks then I might be able to compare them to see what the pipe bend software is sensitive to.

There is a relatively common bug with DXF importers that they don't handle circles and arcs with a plane normal pointing in the negative z axis direction.

In moi.ini there is a setting under
[DXF Export]
FlipNegativeZAxisCirclesAndArcs=n

You might try turning that on and see if that works better.
