There will be many occasions where a user wants to redefine the incidence of one or more members or plates. It would be helpful if there is an OpenSTAAD function to carry out this task as this saves a lot of effort and time.

I understand that there is a menu option under Tools -> Redefine Incidence for members. However, I believe that there is no function available in OpenSTAAD for the same.

Similarly, for redefining the incidence for plates I believe there neither is an option in any of the GUI items nor an OpenSTAAD function. I understand that the desired result can be achieving by a sequential use of the following two functions:

OSGeometry.DeletePlate() and the OSGeometry.CreatePlate()

However, this messes up with a lot of other things e.g., the existing groups, property assignments etc.

Hence, it will be helpful to have a function to switch the incidence without affecting the other areas.
