Hello
I’m using Dynamo in civil3D.
Is there a way to check or change the normal vector of a selected polyline?
I create a solid by extruding a closed polyline in the normal vector direction.
However, I noticed that the normal vector is not constant at +Z or -Z depending on the polyline.
It would be great if I could make the normal vector of selected polylines constant all at once.
Hi @shirai-a,
If you always want to extrude along positive Z, I would recommend just using Vector.ZAxis.
Sorry.
I want to use the solid extrude node.

Yes.
When you select multiple polylines on the XY plane and set the direction and distance to constant, the problem is that the direction of extrusion of the polylines is different for +Z and -Z.
Need to see the graph you have built to validate. It sounds like you have produced a different graph from what @zachri.jensen and I are indicating.
