I use rotated surfaces 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 drop. This is due to the definition of the surfaces, because they have to be generated in the background again and again using the boundary conditions if a change occurs in the structural system.

Therefore, it is recommended to replace the rotated surfaces by the surfaces of the 'Quadrangle' type, which significantly reduce the amount of data. Furthermore, the quadrangle surfaces also allow you to apply loads to parts of the surface only.
