The Export to CAD tool in ArcGIS Desktop 10.6 does not create blocks in the output DWG file. This works successfully with the data provided in ArcGIS Desktop 10.5.1.

Workaround

The workaround is to rename the seed file, and just append the exported data to that file ArcGIS Desktop. When opened in AutoCAD, the file has blocks which are properly created. This does require adding the following fields to the geodatabase feature class attribute table(s):

• CadType, defined as text, populated with the word "Insert", without quotes.
• RefName, defined as text, and populated with the BLOCK name from AutoCAD the data is supposed to be converted to.
