AutoCAD changed entity handling between versions 2016 and 2017 which broke the import of our DXF files. To be specific, Autodesk is now using the high bits of the 32-bit entity handles for something other than normal entity handles, so any DXF file that contains a handle number that is 0x04000000 or larger now crashes their application. We have applied a fix for this AutoCAD change in Strater 5, but it was not added into Strater 4. There is a simple workaround though to modify our DXF files so they load in AutoCAD 2017.
- Open the DXF in a text editor program like Notepad.
- Find these lines near the top of the DXF file:
- Change the number 4000000 to 2800000.
- Save the changed DXF file. It should now load into AutoCAD 2017 without crashing.
