My AutoCAD drawing is Georeferenced the same as my ArcGIS Project. It seems that it grouped some layers into one Feature such as polyline. I can create a shapefile of the missing layer but I loose the "length" attribute. The layer in question is only straight lines. I am proficient in AutoCAD but new to GIS.</P> Fri, 26 Apr 2024 15:20:44 GMT https://community.esri.com/t5/arcgis-pro-questions/conversion-cad-to-geodatabase/m-p/1415896#M82444 Yosteee 2024-04-26T15:20:44Z https://community.esri.com/t5/arcgis-pro-questions/conversion-cad-to-geodatabase/m-p/1415946#M82448 <P>Your observation is correct, the import of an AutoCAD dwg groups data by ArcGIS primatives - ploylines, polygons, etc. It can be tough to find things if you have lines and polygons in the same layer that get sort of separated in the map.</P><P>With regards to losing the length attribute - that is one of many dwg elements that are read-only and not stored as an attribute of the object.
