We have been seeing users experience errors importing CAD files into UniCam, particularly files in the ODB++ format.
The scenario is as follows:
User imports a CAD file and it imports fine with no problem. However, the next job they start working on they can no longer import the CAD and get a “Fatal Error” message. In fact, they cannot seem to import any CAD file for any job.
The solution is as follows:
When a CAD importer runs it creates a folder, “$cadtemp”, which is normally deleted automatically when the importer finishes. Sometimes the $cadtemp folder doesn’t get deleted and that causes all kinds of importer problems, one of which you’re experiencing. For some reason, this seems to happen primarily when importing ODB CAD files.
The path you are looking for is, “C:\Users\<your windows login name>\AppData\Local\Temp\”. Look there for the $cadtemp folder and delete it if it exists. Then try to import your CAD file again.
