The additional options within the Detail settings of the functions "Move," "Rotate," or "Mirror" are suitable for this, see Figure 1.
Provided that it is necessary to draw an annular surface, whereby the center point, and inside and outside radius are known, proceed as follows:
- insert a node on the inner radius and the outer radius
- connect the two nodes by means of a line
- select these three objects
- open the "Rotate" function
- activate "Lines Between Nodes", as well as "Surfaces Between Lines"
- pay attention to the type of connecting lines created when rotating
In RFEM and RSTAB, it is not possible to use the symmetry of the structure to calculate only a half of the structure.
However, it is possible to create only a half of the structure including the loads and then to generate the other half by using the menu tool "Edit → Select → All" and then "Edit → Mirror." In the Mirror dialog box, it is necessary to select the "Create copy" option and the "Copy including loading" option under [Details] (see Figure 01).
In this way, you can omit the supports in the mirror axis and obtain more realistic results.
