macro to scale selected object at point of selection

i had a macro that did this in the past and lost it and cant find a list of special charachters for diesel. Can you point me in the right direction for a list or write it

When you say "point of Selection" there are many ways to do this, the easiest would probably be to use the two returns from entsel.

(setq ent (entsel "\nSelect Object: "))

Returns something like:

(<Entity123> (12.5 43.1 0.0))

Hence you now have an Entity and a Point to work with

now how would i encorporate that into a macro?

 
^C^C_scale o (setq ent (entsel "\nSelect Object: ")) 0.5

Personally, I would write a LISP and call it from a macro - much tidier imo.

heres my stab at the lisp. Is there a way to make it so the point a click to select object is also the point to scale at? or maybe that if i select an object by clicking on it not by a window it scales at that point and if i use a window it scales where the window started at

(defun c:half (\A)
(setvar A(getobj "\nselect object to be scaled")
(command "._scale" "o" "A" 

If you follow the advice I provided in post #2, the answers are all there.

so i use ent to enter the object but how do i enter the point, i see your return shows a point but not sure how to get that into the code.

still want to know how to finish this in lisp but

^C^C._scale \ @ 0.5;

scale at selected point

 
^C^C._select;\._scale;_p;;@;0.5;

scale from start of window

found it from an old post i made

in Lisp:

(defun c:half (/ ent)
 (if (setq ent (entsel "\nSelect Object: "))
   (command "_.scale" (car ent) "" (cadr ent) 0.5))
 (princ))

No problem. I'm trying to feed people clues instead of just replying with the solution straight off
