When you want to change the reference for a temporary dimension, move its witness line.
- Select an element.
- Do one of the following:
- Drag a control for the witness line (the blue dots shown in the image) to a different reference.
- Right-click the witness line control, and click Move Witness Line. You can then move the witness line to a new reference.
Note: Modifications to temporary dimension witness lines are saved on a per-session basis. For example, if a default temporary dimension measures the distance between the centers of two walls and the witness line is moved to measure to the faces of the walls, subsequent selection of the wall preserves the location of the edited witness line for that session.
