Selecting in Plane
Tips & Tricks
In RFEM and RSTAB, there are several ways to select a part of the structural model for further processing. The most frequently used selection option is certainly the ‘selection using window’. Depending on the size of a structure, the simultaneous selection of several areas of the structure using this option may be time-consuming since the unwanted model parts are selected as well.
In this case, you can use the ‘Select in Plane’ option. Thus, you can quickly select and further edit the structural elements lying in a specific plane (for example hall frames or platform levels). You can find this function under ‘Edit’ → ‘Select’ → ‘In Plane’.
In RSTAB, you can select nodes and lines, in RFEM surfaces and members in addition. The plane from which the elements are to be selected can be defined by ‘3 Nodes’ or by ‘Polygonal boundary’. The ‘3 Nodes’ option allows you to select three nodes of the structure of three grid points of the current work plane in order to define the desired plane. The example figure shows three nodes of the structure selected. When selecting grid points, please note that the currently adjusted work plane lies in the plane desired for selection. If necessary, you can adjust this by setting a new work plane or grid origin.
