Modify instance properties to change an isolated foundation's constraints, rebar cover, structural material, and more.
To change instance properties, select the element and change its properties on the Properties palette.
| Name | Description |
|---|---|
| Constraints | |
| Level | The level to which the slab is constrained. |
| Host | The level to which the host of the isolated slab is constrained. |
| Height Offset from Level | Specifies the elevation of the top of the isolated foundation relative to its level. |
| Moves With Grids | Changes the column constraint to grid. |
| Materials and Finishes | |
| Structural Material | Specifies a material for the structure of the element. This information can be included in schedules. Click the value box to open the Material Browser. See Materials. |
| Structural | |
| Rebar Cover - Top Face | Specifies the distance of the rebar cover from the element top face. |
| Rebar Cover - Bottom Face | Specifies the distance of the rebar cover from the element bottom face. |
| Rebar Cover - Other Faces | Specifies the distance of the rebar cover from the element to adjacent element faces. |
| Estimated Reinforcement Volume | Specifies the estimated reinforcement volume of the selected element. This is a read-only parameter that only displays when rebar has been placed. |
| Dimensions | |
| Elevation at Top |
Indicates the elevation used for tagging the top of the foundation. This is a read-only parameter that reports Varies for sloped planes. |
| Elevation at Bottom |
Indicates the elevation used for tagging the bottom of the foundation. This parameter is affected by the family parameter Cap (see Specify Family Category and Parameters). The following image shows the difference between the Cap parameter enabled (in red) and disabled (in green).  The Elevation at Bottom measurement is taken from this setting. This is a read-only parameter that reports Varies for sloped planes. |
| Identity Data | |
| Comments | A field for entering comments about the wall. |
| Mark | A label created for the element. This value must be unique for each element 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 Review Warning Messages. |
| Phasing | |
| Phase Created | Indicates in which phase the component was created. See Project Phasing. |
| Phase Demolished | Indicates in which phase the component was demolished. See Project Phasing. |
