Topic: Maximizing An INSERT In A Display Area

[David Bethel]

Greetings,

I'm updating our detail pages for individual pieces of equipment. 
Normally there are (1) Plan, (2) Elevations and (2) Isometrics ( as shown )
and lots of notes and dimensions

1/2" = 1'-0" and 8.5 x 11 p[aper ( landscape )

Based on the size of the equipment, I can calculate the display area
LowerLeft and UpperRight points for the isometrics

The isometric is a BLOCK that I can determine the boundry box
X and Y axis values

The BLOCK insbase point is always the LowerLeft of the bounding box

What I want to do is to maximize the INSERT scale so that the INSERT takes
up either the entire X axis or Y axis and not extend betyond the display area
while being centered in the display area.

( The INSERT scales will always be equal )

Any suggestions would be greatly appriciated !

I would scale the insert based on the bounding box.
This may help in that endeavor.

Thanks CAB

Yes, the scale is what I'm working on.  Almost there but not quite.  Thanks!  -David

I'll have to tweak this for my personal needs, but it seems to work :

Code: [Select]

;;;INSERT A BLOCK INSIDE A DISPLAY AREA
;;;LowerLeft UpperRight BlocksiZe BlockName
(defun fill_disp (ll ur bz bn / vx vy vc is ipt)
  (setq vx (- (car ur) (car ll))
        vy (- (cadr ur) (cadr ll))
        vc (list (+ (car ll) (* vx 0.5))
                 (+ (cadr ll) (* vy 0.5)))
        is (min (/ vx (car bz)) (/ vy (cadr bz)))
       ipt (list (- (car  vc) (* (car  bz) is 0.5))
                 (- (cadr vc) (* (cadr bz) is 0.5)) 0))
  (command "_.INSERT" bn ipt is)
  (while (> (getvar "CMDACTIVE") 0)
         (command ""))
  (list bn ipt is))
