Hi. Im working in Allplan precast and having some problems with the building structure.
Often when i change heights i loose some of the structure. The drawing files is still in the project but i have to build up the structure again. And assign the drawing files again. This is costing me precious time and is very annoying. Can somebody please tell me why this is happening. Is there something i am doing wrong that cause the problem or is this a glitch in the software?

Ps: i dont know if this is even the right fora to ask but il try anyway=)
