Why does the "Undo Function" only work for two or three processes (after that, it is grayed)?


When editing a model it happens again and again that the just executed work steps have to be reversed. However, how far you will be able to undo executed work steps depends on the size of the buffer memory defined for it. In the case of a very large model with many loads and load combinations, the preset value is often insufficient.

It is therefore possible to adjust the buffer size for the undo function individually in the "Program" tab of the program options.
