Simple polyline offset to different layers?

Offset pline fails on some lines

i’m trying to offset polylines and to get a polygon out of a single line. [OFFSET_2020-11-16_01-20-36] OFFSET.dyn (123.5 KB) offset_test.dwg (527.6 KB) some lines fail, and output a 3d polyline, what i was expecting was a closed polyline. what am I missing?

Curve.Offset direction is inconsistent

For some reason the Curve.Offset function in Dynamo/DesignScript does not produce consistent results relative to curve direction. As an example, try drawing lines from the center of a circle to even divisions around that circle - then offset those curves. You’d expect a radially symmetrical figure, but instead it “flips” at a certain point. compare the results between GH and dynamo: [image] what gives?!
