Problem

When importing a DXF file using ModelBuilder the following error appears:
"Attempted to read or write protected memory. This is often an indication that other memory is corrupt."

Solution 1

If the original CAD line work was exported to a DXF file, then try saving as a DXF instead.

Solution 2 (Requires version 10.00.XX.XX)

In one case, there was an issue with the original DWG that was saved to a DXF file.

The release of the CONNECT Edition version of the products (10.00.XX.XX) introduces the ability to use MicroStation DGN files in ModelBuilder.

Open the DXF file using a CAD editing application (eg. MicroStation, AutoCAD).
Save as a DGN.
Use the DGN to import the data into ModelBuilder.

Solution 3

Open the original CAD file in a CAD editing application (eg. MicroStation, AutoCAD).
Save the file as a DGN.
Save that DGN as a DXF.
Use the new DXF to import the data into ModelBuilder.
