Hi Mark, normally those kinds of coordinates are used for feet and inches type units only.

You need to have your unit system set (under Options / General) to something other than "No unit system", and then you can enter in those kinds of coordinates if you include the ' and " marks along with them, like for 8 1/2 feet you enter this:

8 1/2'

Normally when you want that style, you should go to Options / General, and set "Unit system: Feet & Inches".

That will cause the base units to be in feet and all the coordinates and distances will be displayed using that fractional type style, like 8' 2 1/2".


Otherwise if you want to do it for something other than feet or inches that is possible by typing an expression using the + sign, like: 2+1/2 , that will result in 2 + 0.5 = 2.5 units.

Using the + method will work with any unit system and not just for feet and inches.
