When you fill a curtain wall cell with an object, such as a door or window, that object is anchored to the curtain wall. While the anchor is in place, the object moves when you move the curtain wall and is removed when you erase the curtain wall. If you want to move or erase an object independently from the curtain wall, you can release the anchor of the object.
Note: You can also move or erase the object by changing the element definition for the cell that contains the object.
- Select one of the objects from the curtain wall, right-click, and click Infill Anchor
Release.
