Align Ducts to Grid

Snap to grid lines provides an easy way for you to space the ducts evenly and according to their real world spacing. The steps below explain how to use Snap to grid and adjust your ducts to align to the grid.

Start by selecting a duct in the Duct Layout tab as your target duct with which to create the grid from. This selected duct is referred to as the target duct. To activate the Enable snap to grid button.
Click Enable Snap to grid button and the grid appears in the Duct Layout Tab. The grid automatically centers on the selected duct (grid cross hair aligns according to the center of that duct).

The size of the grid is automatically configured in relation to the size of the target duct selected when you click on the Enable Snap to grid button. Selecting a different target duct may create a different grid size.
Click Configure grid button to display the Configure grid dialog on the Layout Editor pane. Any duct that is already snapped to the grid displays with a double outline as illustrated with Duct G in the image below.

TIP: You can set a different duct as your target duct by selecting the duct, right-click on it while still selected, then choose Align grid to this duct from the right-click menu.
In the Configure grid section, the Grid size X and Y values can be adjusted to any value larger than 0. Changing these values adjusts the distance between the grid lines making the grid size larger or smaller.

Underneath the X and Y values, the Line weight slider changes the thickness of the grid lines so they display thicker or thinner according to your preference as illustrated below.
Click Apply when you have finished changing any of the Configure grid settings you want to apply to the view.

TIP: If you don't like how the new settings look, click Configure grid again to change the settings again.
Setting one of the X or Y values to a small enough number can make it look like there is no space between your grid lines.
Once your grid settings are as you like, you can move the ducts around the duct bank and they will snap to the intersections of the X and Y grid lines.
When you have finished snapping the ducts to grid, click Save. The grid lines automatically turn off when you save.
To turn off the grid lines, click the Enable snap to grid button. When grid lines are already turned on, the tool tip for that button displays as Disable snap to grid.
