Modeling Spring Using Trajectories

In RFEM, you can create screw lines using the "Trajectory" type line. To do this, you need a center line/guide line around which the line can be modeled, as well as a start and end point. Then, you can create a "Trajectory" type line between the start and end points; this initially appears as a straight line.

Spring with Trajectory

In the "Edit Line" dialog box (available when you double‑click the line, for example), there is a new "Trajectory" tab, which includes settings of a special type. In this tab, you can select a guide line and a rotation angle around the guide line. Finally, assign the created helix to a member in order to complete the model of a spring.
