# Floor supports
* Use the **Floor Supports** command to define Revit floor supports prior to using **Panel Layout** subdivision functionality.
* Select **Floor Supports** from the **Floor Panel Layout** menu.
* Select **Add Supports** in the **Floor Supports** menu.\
Note: Floor supports may be structural framing (beams), walls, or grid elements.
* Follow the instructions by picking floor and supports.
* As floor supports are added, a **Split Line** will be generated at the center of the support element.
* Floor panels will be cantilevered or offset from the selected support elements by the values input in **Panel Settings** - **C**\
**antilevered Offsets from Supports**
Options in the **Floor Supports** menu.
* **Add Multi-type Supports** - allows different types of supports to be selected (i.e. walls/beams/grids/structural framing)
* **Add Supports** - allows only one type of supporting elements to be selected (i.e. walls)
* **Add Inner Support / Add Two Inner Support** - allows for supports to be selected at the inside of the floor perimeter
* **Add Trimmed Corner Supports** - allows you to form a corner support by selecting two corner elements
* **Show Support Elements** - allows you to see which elements were selected as supporting
* **Update Floor Supports** - allows you to update floor support division (i.e. split lines) if support layout has changed
* **Delete All Floor Supports** - deletes all support elements and split lines which were generated with **Floor Supports** function. All support lines added manually (using Revit functionality) will remain.
* **Delete Selected Floor Supports** - deletes only the selected support and support line. It will update remaining supports according to the changed layout.
