The feature layers are grouped by geometric type. CAD feature datasets in the mapĪdding the entire CAD file to the map generates a group layer of grouped feature layers. To validate the positioning information for any CAD or BIM file, you can inspect the file properties in the Catalog pane and perform a coordinate positioning validation. Notifications will guide you to choose the proper spatial reference, and you will be presented with tools for any necessary CAD data repositioning. ArcGIS Pro alerts you when you attempt to add CAD data that does not have a proper spatial reference. wld) to identify how the coordinates in the CAD data should be positioned on the earth's surface. prj), and may require an optional coordinate transformation information file (. CAD files are required to have a valid Esri coordinate system file (. To use CAD data in ArcGIS Pro, the data must have a defined coordinate location. ArcGIS Pro also reads other feature class content in AutoCAD DWG and DXF format files from AutoCAD Civil 3D and Esri's ArcGIS for AutoCAD. MicroStation-based applications and other applications that use the DGN, DWG, and DXF file formats. ArcGIS Pro accepts data generated by AutoCAD and

These platforms accommodate a range of applications. AutoCAD and MicroStation are two widely used general-purpose CAD platforms. When CAD data is added to a map, the resulting CAD feature dataset of feature classes is accessible as a read-only feature layer. If the save cannot occur promptly enough, in the interests of NOT losing data, Autodesk products will save to the SAVnnnn.tmp or SAVEnnnn.tmp file.You can add CAD data directly as feature layers in ArcGIS Pro. I read somewhere in the Autodesk knowledgebase that AutoCAD &/or Civil &/or Revit will lock a file (or cause the OS or NetOS to lock a file) in the event that timing issues occur during a Save. (In some rare cases, the File > Properties > Details does not show an Owner.) Ours do not seem to be removed by routine garbage collection: Here's a sanitized current list without project or drawing names: Then, it appears, THEY have to be updated to point to their newly renamed xREFs. One problem that ripples out from this is if the file in question that cannot be saved is xREF'd by other files. In many cases it does not crash the program or the system, but simply prevents saving except under a new name, and the folders on our server are littered with SAVnnnn.tmp files, *.ds$ files, and the. We have a similar problem to the AutoCAD 2018 issue in the topic line, except with Civil 3D 2017.
