Calling a field from AutoCad to Pro

[KatelynHLane]

I am using ArcGIS Pro 3.1.3. I am attempting to make a tool in ModelBuilder that makes AutoCad DWG files into polygons that I can use in ArcPro. Most of the tool is working except for one of the last steps. I am trying to calcuate fields for Room Use CPE and room numbers that are located in an attribute table in AutoCad. I have tried calling the field using exclamation points, but they still turn up null.

Hi Katelyn,

Nulls usually mean the CAD attributes didn’t carry over during conversion. Try using the CAD to Geodatabase tool and confirm the field names match exactly — the !FieldName! syntax only works if the field exists in the table. This workflow is the same in newer versions (3.5–3.6), so once the fields are mapped correctly, your calculations should work.
