Member Rotation About Plane

Tips & Tricks

If spatially oriented members converge in one node, the local x- or y‑axes of the members do not lie in one plane, since the local z‑axes are oriented in the direction of gravity. In cases other than what is represented in the figure, this can be easily overlooked in rendering in the case of a small inclination. However, this can be a problem in an RF‑/JOINTS design, for example, as the members do not lie in one connection plane. Therefore, the design is not possible.

So it is necessary to rotate the member about the connection plane. Since the manual calculation of the member rotation would be time-consuming, there is an option to rotate a member about any plane. For this, select the “Member Rotation via Help node” check box and define a node located in the desired plane and out of the rotating member at the same time.
