Hello, you can have a look at BimorphNodes for CAD imports, and also at this thread for a start:

Align objects with a 3d curve

Hello, I want to be able to get a 3d curve from a Revit file. On this curve I want to place equally distanced objects, with the ZAxis always vertical and the XAxis aligned with the tangent of the curve in the point. I’ve tried out several things: horizontal frame at parameter, point at parameter, tangent at parameter. So far I am able to place the objects at parameter. The next thing I need is that the object is aligned with the curve. I want the XAxis aligned at the tangent of the curve at th…
