I would like to import points with imperial coordinates to rhino. I can do it for mm, m, cm, etc. However, when I tried to import foot-inch-eight, it doesn’t work.
I tried with these points saving as CSV file and importing the file in rhino.
I don’t think you will be able to import imperial co-ordinates in feet and inches as shown. However as a workaround, since you are bringing data from Excel, you could convert them to fractional values in the spreadsheet. If your primary unit in the model is feet then use fractional feet, if inches use fractional inches.
