When uploading drawings for a project with multiple buildings, you may find that many drawings are labeled with the same title (e.g. A1). To prevent confusion, you can create different drawing areas, where each building would have its own separate drawing area underneath the project's Drawings tab. The ability to create separate drawing areas within a project makes it easier to navigate within the Drawings tool to find the correct drawings even when there are multiple drawings with the same title and/or number. When the drawings by area feature is enabled and configured for a project, you'll be able to click into the designated drawing area to see drawings associated only with that building.
When you have configured multiple areas in your Drawings tool, they will appear similarly to the example below.
