| Analytical Model | |
| Analyze as | If set to Foundation, the slab will provide support for other elements connected to it. If set to Slab on Grade, the slab will only support itself. |
| Analytical Properties | |
| Family Type | The family type of the element. |
| Physical Material Asset | The name of a physical asset assigned to the foundation slab material (read-only). |
| Area | The total area of the foundation slab. |
| Perimeter | The total perimeter of the foundation slab. |
| Analytical Alignment | |
| Alignment Method |
Either Auto-detect or Projection. Specifies if the horizontal and vertical references of the slab are automatically justified or have a defined projection. |
| z Projection | Either Top of Element, Center of Element, Bottom of Element, <Level...>, or <Reference Planes...>. Available when Alignment Method is specified as Projection.
If in sketch mode, this parameter will default to Floor/Slab edge for either the whole model sketch or just a sketch line. Specifies the vertical location of the analytical model at the base of the slab. |
| Identity Data | |
| Surface Number | An identifier created for the analytical surface. This value should be unique across Analytical Floors, Analytical Foundation Slabs and Analytical Walls in a project. Revit warns you if the number is already used but allows you to continue using it. You can see the warning using the Review Warnings tool. See Reviewing Warning Messages. |
