subtract distance

don't know how to figure this out. Once I set my distance how do I subtract from it? 8" typ

Do you mean that the line is already made and you'd like to cut 8" (8 inches) from the line ?

Thanks

that is correct

(defun c:example (/)
 (setq di (getdist))
 (setq disub (- di ...;;however it needs to be worded

Would the CVUNIT function be of any help? Check out the AutoCAD developers help files for info

Check this link and the post #7 by Alanjt is what you looking for.

I'm not sure I completely understand your question about it being worded?

I'm sorry, I have no idea why it didn't work earlier. I'll have to check what was mistyped at work

what I wanted

(defun c:example (/ di disub)
 (setq di (getdist "\nSpecify distance: "))
 (setq disub (- di )
 (alert (strcat "Outside dimension = " (rtos di 4) ". Inside dimension = " (rtos disub 4) "."))
 (princ)
)
