Deformation Analysis of Members on Polylines in RF‑DEFORM

I have defined a member on a polyline. Now, I get an error message saying that there is an unsupported member type when performing a deformation analysis of this member. What is the cause and how can I fix it?

Answer:

In RF‑DEFORM, you can only design members that are defined on a single line. Otherwise, the error message shown in Image 01 appears.

Error Message "Unsupported member types are assigned!"
1 Error Message "Unsupported member types are assigned!"

You can use the "Explode Polyline" function to decompose the polyline (Image 02). For straight lines, we recommend deleting the redundant intermediate nodes (Image 03). Then, deformation analysis in RF‑DEFORM is possible.

Function "Explode Polyline"
2 Function "Explode Polyline"

Function "Delete Node"
3 Function "Delete Node"
