Those of you that have made custom changes to Parts List and added Optional Parameters, may have come across this little error message upon launching Civil 3D:
This typically occurs for one of two reasons. One being that your AeccPartParamCfg.xml file has been configured incorrectly to reflect the custom parameters. The other reason being that your custom template, with these parameters added to your parts list, has been path’d to the QNEW location from OPTIONS>FILES tab>TEMPLATE SETTINGS>DEFAULT TEMPLATE FILE NAME FOR QNEW.
For information on how to correctly configure your XML file please refer to my previous blog post explaining the process: Assigning Optional Properties to a Part Size
If you have noticed this error message because of your template being set in your QNEW path, this is something that Development is currently looking into. I would like to note that these error messages appear to be benign and I have confirmed that you can still use the Optional Parameters without issue after clicking the “OK” button on the error message. The downside of this would be that if you have 63 Optional Parameters, you will get 63 error messages at launch.
However if you open the template AFTER Civil 3D has launched, (leaving the QNEW pointing to something like the stock NSC template) you will not get these error messages. So although it may not be ideal, you can still use these Optional Parameters effectively in your designs.
