How to manipulate setbacks in TestFit

Setbacks allow architects and developers to easily incorporate zoning laws set by cities. Setbacks in TestFit are owned by the site definition lines and can be manipulated in 2D or 3D to adjust the envelope of the building.

In order to edit a setback, you must select the site line that would drive the setback. Then you can either edit it in 2D in the Site panel or in 3D in the view panel.

Setbacks in 2D

To adjust basic setbacks in plan view, drag the setback to the desired length. You can reset all setbacks or apply this setback to the rest of the edges.

Custom Setbacks in 2D

After selecting the site line that you would like to add a setback to, you can place a point on the dashed line in the Site panel to add a new setback at that elevation. Click and drag the box to the left of the setback to adjust the setback.

In the site panel you can adjust whether the setback is clamp trailing or linear trailing.

You can also adjust how small or large the step of the setback is.

Setbacks in 3D

To create a setback in 3D, select the site line you would like to add it to (a blue plane should appear). Hold shift until a + sign appears, then click and drag on the plane to add a setback.
