Origin point out of the cross section,when create beam with a polyline

when create a beam with a polyline(or curve),if the origin point out of the cross section, cannot create the beam.

if the origin point on of the cross section, can create the beam. (MAYBE A BUG??)

when create a beam with a straight line ,whatever origin point on or out of the cross section, can create the beam.

Adjust position to center center

My goal is to have all cross sections have the same control point, so that mirroring or component control will be more easier

when i create many parts as a assembly, ajdust position to center,the model with Curve(arcs) comes out wrong radius.

i think it’s a BUG!
