In a model, you can use the grid to ensure that objects are correctly aligned with one another. When aligning an item to the grid the system ensures that its center point is placed exactly on the grid.
If you set the special grid mode and entered a value below 30 for the grid width, the special grid mode will automatically be turned off. To indicate this, the Special grid mode check box is disabled.
Double-click the model background. The properties dialog opens.
Click Grid on the Selection tab.
The Grid width area provides you with various options for setting the grid width:
Move the slider to the left to increase the number of grid dots; the spacing between the grid dots will be reduced accordingly. Move the slider to the right to decrease the number of grid dots; the spacing between the grid dots will be enlarged accordingly.
Enter the required grid width in the spin box.
Click the up or down arrow in the spin box to increase or reduce the grid width.
Click OK.
Grid settings have been changed.
Tip
The special grid mode can be used from a grid width of 30. If you set the special grid mode and entered a value below 30 for the grid width, the special grid mode will automatically be turned off. To indicate this, the Special grid mode check box is disabled.
