I use surfaces of revolution in my model. Now it takes a long time to open and edit the file. What can I do about it?


Rotated surfaces are often used in RFEM to easily model and calculate geometrical conditions. However, if you use a large number of rotated surfaces in the model, you may experience performance drops. This is due to the definition of the surfaces because they have to be generated in the background again and again by the boundary conditions when a change occurs in the structure.

Therefore, it is recommended to replace these rotated surfaces with surfaces of the type "Quadrangle" which significantly reduce the amount of data. For Quadrangle surfaces, it is also possible to apply loads only to parts of the surface.
