When spot elevations or spot coordinates are applied to line-based host components, you can specify that they orient to the component and not the horizontal default.
Line-based host components are those elements placed by defining a start point and an endpoint, such as structural walls, walls, beams, and braces.
- In the drawing area, select the spot coordinate or the spot elevation.
- On the Properties palette, click
(Edit Type). - In the Type Properties dialog, under Constraints, select Rotate with Component.
- Click OK.
The spot dimension will now rotate with a component as shown in the images below.
