Using math in command bar

jeroendewind — Fri, 28 Jul 2017 10:24:57 GMT

Hi all,

I would like to know if there's an easy way to do some calculations in the commandbar during a command. Whenever I can, I like to use the divide to get the value I want, for example: 5400/9. Unfortuatly it's not working with multiply, add or subtract, what is the reason for that?

I know I can open up the calculator in AutoCAD, or use the 'cal command to do some math, but isn't it just possible to do all the math as easy as with divide?

Thanks

I'd rather use it without adding a commando first, but to be fair; adding 'cal isn't really much of an effort.

The problem of 'cal is that I'm losing my first point, direction and polar.

Use can use LISP commands.
(+ 5400 9)
(- 5400 9)
(* 5400 9)

Other arithmetical functions see HERE

(/ 5400 9) =600

(/ 5400 7 will give 771)

always include a decimal in one of the numbers to prevent rounding when dividing if rounding is not desired

( 5400 7.0) = 771.429

Thanks, it works allright with (* 50 25) etc.

It's a little bit strange but I can get used to it!

Thanks
