Title: zooming
Post by: curmudgeon on April 18, 2009, 04:13:22 PM

I would like the computer to escort me through my building, sometimes one room at a time.

I can make a selection set of room numbers and zoom center to the insertion points, it works. but is there no better way?
say one room is a closet and the next a gymnasium. the zoom scale for one will not work well for the other. I can just as easily get the outline of the room. but what can I pass the max and min of the x & y to and get a nice tight fit of only what I want to see?

the system variables that I can find that pertain to the size of a view screen are all read only.
 :-P

Hi,

Assuming pt-lst is the points list of a room outline, the following expressions returns the min and max points you can use for a window zoom

(apply 'mapcar (cons 'min pt-lst))
(apply 'mapcar (cons 'max pt-lst))

Code: [Select]

(apply 'mapcar (cons 'min pt-lst))
(apply 'mapcar (cons 'max pt-lst))
=>
