Please HELP:Retrieving dimensions of a rectangular REGION

Hi everybody, let's see if someone can help in solving this problem:

I got a "REGION" entity obtained from a polyhedral 3D solid with the
"solidedit - face - copy" command . The REGION is rectangular.

How can I retrieve the size of the rectangular (height and width) from
inside an AutoLISP routine?

This is very useful for my project...so please HELP if you know.

Thanks a lot

tunnel!)

 

Try this:

(vla-getboundingbox
(vlax-ename->vla-object (car (entsel)))
'minpt
'maxpt
)
(setq LowLeftPt
(vlax-safearray->list minpt)
)
(setq UpRightPt
(vlax-safearray->list maxpt)
)

Otra alternativa es usar las propidades de la región,

en particular perímetro y momento de inercia que son valores
independientes del sistema de coordenadas.

si se trata de un rectángulo, perímetro y momento de inercia se
expresan como función de los lados.

con un poco de álgebra, podrás despejarlos.
