FAQ: Do AutoCAD DWG and DXF files display differently in ArcMap at version 10.4?

Question

Do AutoCAD DWG and DXF files display differently in ArcMap at version 10.4?

Answer

To avoid drawing all these individual BLOCK layers in ArcMap, just add the Annotation, Point, Polyline, Polygon and Multipatch layers to the map as was done previously.  To add these specific feature types in the Add Data Dialog or in ArcCatalog, double-click the CAD file name and add only the feature types needed to the ArcMap document.

Individual BLOCK layers can also be added to ArcMap along with specific feature types.  This provides access to the values in the attribute TAGs for each type of BLOCK.

Esri recommends not adding the Group Layer from a CAD file to ArcMap, because the Group Layer masks too much information about the data, and also adds all the BLOCK layers to the map, causing a performance lag.  This is documented in BUG-000094769: "DWGs added to ArcMap 10.4 take several minutes to load and may eventually cause the application to hang."
