    Introduction  

    Project Units by default are under the Manage tab>Settings Panel>Project Units. Open the rac_advanced_sample project and in the Project Browser double click on the level 2 floor plan view to open it. Now zoom in on the top left corner of the floor plan and run a dimension string between grid lines 1, 1.1 and 2 as shown. The dimensions are showing in millimetres because the project units are at millimetres. Click on the length label to open the Unit Format dialogue box.

    In the Project Unit Format Dialogue box, click the drop down on Millimetres and change it to Metres. Next change the Rounding to 2 decimal places and the Unit symbol to m. On screen the dimensions will update to reflect this input.

    Select the dimension string and type CS (create similar) on your keyboard, click Edit Type, click Duplicate and rename: Diagonal-2.5mm-Arial-Imperial. Still in the Type Properties dialogue box, scroll down and click Units Format. Uncheck use project settings, change units to feet and fractional inches, change Rounding to the nearest ¼”, tick suppress 0 feet. Now run another dimension string underneath the original as illustrated. The dimensions now show as imperial.

    Conclusion

    Just because the project is set to be metric doesn’t mean the dimensions have to be metric or my area has to be metric. I can have a metric project with imperial dimension and visa versa. You can therefore work in imperial and metric simultaneously in the same project.
