# Grid Numbering

**Grid Numbering** - opens the numbering dialog for the Grids category.

**Filter -** Grids can be filtered by the following parameters: All, Vertical, Horizontal, Diagonal, or Arc.

**Mark Symbol** – the first mark symbol for the active or selected grids below.  **Mark** – enters new grid names in 'New Name' column.

If needed, the names of the grids can be changed manually as well.

**Change Last Symbol** – changes the last symbol letter in the 'New Name' column according to entered 'Mark Symbol' value.

Example:

**Automatically Sort Grids** - automatically sorts or changes the names of grids when the user makes any changes in a project.

For example, user adds a 'B' grid in a project – other grids are automatically renamed accordingly:

**Pseudo Marks** - Revit creates pseudo marks for repetitive grids.

For example, grid number 7 has been inserted between grids 1 and 2. After the renaming process, all vertical grids are renamed with numbers from 1 to 6. When the user selects OK, a warning window pops-up because a diagonal grid with name 6 already exists. Revit does not allow grid names to be identical, so Sort Mark creates pseudo-marks for the repetitive grid.
