I went into settings and chose imperial units for my project. When I import an AutoCad file and go through the process of locating the origin and scaling for units, I chose "feet". I chose a door that I know to be 3ft wide. When I choose "Foot", the measured length show up as 36 ft. When I choose "Inches", the measured length shows up as 3 ft. It seems like the two options got mixed up.

I decided to use "foot", even though the measured length was incorrect. After the setup, I measured the door using the tape measure. When I choose the Unit of Measure as "Inch", it shows the correct 3ft. When I choose "Feet", the door measure 36 ft.

This is very confusing, and it makes me not trust any calculations or other aspects of Dialux that I might use. Am I misunderstanding how the units of measure work or is this something that needs to be fixed?
