You can create a building structure in several ways:
You can create the building structure using the floor manager. If you use this method, you can create the building structure and the objects derived from the building structure in one go. At the same time, you can assign height settings to the structural levels.
You can configure the program to create the building structure automatically the first time you open the Building structure tab. If you use this method, you can select a building structure that comes with Allplan.
