Constrained linear dimension

The Constrained Linear mode creates a dimension line with a single measurement.

To create a constrained linear dimension line with a single measurement:

Click the tool and mode, and then select a Dim Std (dimension standard).

Click to set the measurement start point.

Click to set the end of the measurement.

Move the cursor away from the object to the desired offset location.

In a 2D view, the dimension line preview is constrained to be parallel to either the X or Y axis of the layer plane. In a 3D view, the first two clicks determine the X axis of the plane where the dimension will be placed; move the cursor to rotate the dimension plane. The dimension plane can be horizontal or vertical to the layer plane, or aligned to adjacent faces of a 3D object being dimensioned.

Click to place the dimension line.
