The Pit
A new object - a Lift Pit is automatically created on the basis of an opening defined in the foundation slab, and its dimensions depend on the dimensions of this opening.
The pit has a set of Slab and Wall parameters that can be modified parametrically (thickness, boundary conditions, interpretation, etc.). For the walls of the pit, it is possible to define a thickness variable in height.
To select the analytical representation of the pit walls, use the parameter Create walls - Yes/No:
- Create walls - Yes - the walls and the slab have an analytical representation of the Plate;
- Create walls - No - the plate has an analytical representation Plate, the walls are replaced with an Offset.
