Timothy,
We've run across this before. The answer for us was 'No'. Your CAD files are your instruments of service, hence the Architect's sole property. One assumes you have customized your CAD program with your own office standards, library parts etc. and these are for your/your offices' use only.
We faced serious pushback from one client - we told him that we could potentially give him the CAD files, but only after reviewing them and stripping out any of our proprietary information, which is very time-consuming considering these are often deeply embedded in the file. The hourly cost to do that was prohibitive. He decided to pursue preparing his own documents, simply for cost reasons, not because he wanted to do the right thing.
Look at it this way: Would an author give his word.doc to the publisher? No. Hope this helps. Best Regards,
Heather
