Units by Project

We have clients in several parts of the world. Some use the Imperial system, and some use the metric system. Would it be possible to get a unit system assigned by a project? And not change it as a general parameter that affects everything?

Hi there!

Thanks for contributing your inquiry to our forum. At this time, units are determined for an entire account profile via the Preferences tab. Unfortunately, this is not currently project-specific.

That being said, the preference chosen by the viewing party will be applied to anything shared with them. (For example; if your preference is set to imperial and you share with a user’s who’s preference is set to metric, they will receive your map in metric units.)

Thanks for your feature request, I can certainly flag project-specific units to our product team for consideration. :slight_smile:

Can we get Units divided into International Feet and US Survey Feet?

Currently all Exports are in Inches and I have to manually edit the DXF file and modify the following:





So that it’s Imported as US Survey Feet.

Could you clarify this? All of our exports are (ftUS) decimal feet. What EPSG are you using? I use 2277 and 2278. This might solve this thread.


I typically use EPSG: 6588 and every DTM - DXF has been set to 1 in the file which is Inches.

Here is the Autodesk INSUNITS look-up table:

Initial value: 1 (imperial) or 4 (metric)

Where did you get 6588 from? What is the specialization? I find it best to use 2275-2279 for Texas on most design files.

INSUNITS is typically used for defining inserts. It is typically 0 by default and will follow the drawing setup. Command _ddunits is the drawing itself and command setup is where you put in your projection and scale factor.

This is the latest codes from 2011

Just found them, thanks!
