On Land

Environment Information
At Rill Architects we run ArchiCAD on macOS. If you work at Rill, this is your stuff. If you don't, but you work in ArchiCAD, you may find something interesting. Anybody else, I don't know.

Perhaps you are looking at an element in an S/E window, and want to find the element in the plan.

Select the element in the section. Drag it somewhere. Undo. Return to the plan. The element will be selected. Or, delete it, and Undo.

Caveat: The plan window must be on a story where the element is showing. Use Zoom to Selection to find it. If Zoom to Selection shows only the S/E element, you're on the wrong story.
