@staciejonesy that screen capture showing more lines is perfect.

and that blank drawing screen is perfect for testing too

now I could see you set the UNITS command in this blank drawing for surveyor

then start your line command pick a point any where on the blank screen

then enter your surveyor units entry

then again show more of the command line

And now I see AutoCAD returning invalid point. This looks like a bug with your AutoCAD Mac version.
