The Grid Creation dialog box is displayed.


2. Specify the parameter values for the grid:

Construction planes are created outward from the element's axis. If you are creating construction planes in an area along the X or Y axis, as soon as you enter a step size, the system calculates the number of construction planes that will fit in each direction and displays the values in the following fields:

If you select an XY Grid Type, the number of steps is calculated, and the Number(+) and Number (-) fields are not displayed. If you are creating construction planes in free space or along the Elevation (Z) axis, the number of steps cannot be calculated. A default value is used for the number of steps. When the Grid Type is set to Elevation (Z), the number of steps is displayed as:


You can change the number of steps.

3. Select OK to create the construction planes.
