Offset half a dimension
Is there a way to automate dividing a length in half and offset the halved amount? I have the centerline of a room and in this instance, want the total offset amount to be 15'-2 1/2", resulting in two offset lengths of 91.25". Instead of manually converting feet/inches to decimal inches, dividing by two then offsetting, is there a way to speed this up?

(defun C:OffsetHalf ( / ) (command "cmdecho" "1" ".offset" (/ (getdist "\nTotal offset distance: ") 2.0) pause "_b" "") (princ))
Copypaste into the command line, invoke by typing in the name, and see if this does the trick for you.

Typically what I do is offset a line 15'-2 1/2" apart, draw a line or use midpoint between two lines and move the midpoint of the new line onto the centerline.

This is perfect, thank you. It's now loaded into my on_start.lsp file, I shortened "offsethalf" to "oh" to make it a little faster to type.
