External References in ACA
➲I
n this article, Melinda Heavrin will take a look at external references (xrefs) and how they can work for you.
The Drawing Management feature in AutoCAD Architecture 2019 uses external references (xrefs) as a means to create a project and maintain it. What this means is, elements are referenced into constructs, constructs are referenced into views and views are referenced into sheets. The mechanism of referencing is identical to the regular AutoCAD External References Management feature. However, the background methods employed have additional features. 26

Xrefs that have been created in drawing management can automatically make use of project data, while those that are created manually through the xref palette or command line cannot. For example, a construct that is placed on a specific level will use that level’s elevation data to control the Z-axis insertion point when being xrefed into a view. If you are working in a project environment, the best practice for referencing project drawings into other project drawings is to use the Project Navigator rather than the standard AutoCAD Architecture Xref Manager. The AutoCAD Architecture Xref Manager cannot differentiate between project drawings and non-project drawings. If you reference a non-project file into a project file by mistake, you cannot use the full Drawing Management functionality on that file. February 2020
