You are very welcome. Do you plan to upload the finished DC to the 3D Warehouse? I could use a copy if you are willing to share it.
I see you are based in the USA, so you are probably using feet and/or inches, and/or fractions.
But be aware that converting DCs to work in metric units brings in a whole new range of unit conversions, and some bugs.
See this very recent thread, and the link in it to an old thread on the subject.
