Everyone knows that Civil 3D is a civil engineering application. After all, it’s in the name, right? And civil engineering projects use meters and feet (both US and International.) By the way, that’s decimal feet, not those annoying inches that architects work with.
Today, I was part of a conversation about architectural units in Civil 3D. The question was “Is it possible?” The answer – no. See, units in Civil 3D are not controlled by the UNITS command as they are in AutoCAD. Units in Civil 3D are controlled on the Units and Zone tab of the drawing settings dialog. Looking at the pulldown there, you will see that there are two options – feet and meters. That’s it – nothing else. Besides it not being available, it’s just not a good idea – ambient settings, input dialogs, etc. are just not set up to recognize inches.
This is not to say that your Units and Zone tab of drawing settings cannot show inches. I’ve seen it, although it is VERY rare. This normally involves some form of drawing corruption that occurs when civil drawings and architectural drawings interact in a certain way – I still haven’t figured out how to trigger it, but the fix is to set your units back to feet (or meters) as soon as possible.
