Set a Fixed Point for the Building Component Library Swap
You can select a fixed point from a building component when replacing the component with a component in a different library. That point will remain in the same place. The fixed point matters when the original and the new component are of different sizes.

Set Fixed Point for Building
Component Library Swap. - Select a component.
- Select any point in the component as the fixed point.
Note:
- A fixed point selected for a window or a door will also determine the unmoving point when you resize the opening by editing its properties.
- If you do not select a fixed point, the program will use the locating point last used as the fixed point when the location of the original component was defined.
