drawing area containing entities

Hello all

I want to write a reactor program which performs a zoom all whenever a new entity is added to the drawing. For this I need to find the drawing area which contains all the entities i.e. the corners of a rectangle which encloses all the entities contained in the drawing. So that I can use these coordinates in vla-zoomwindow function. Their are 2 variables extMin and extMax but they do not fulfill the requirement.

So please guide How to find the above mentioned coordinates.

Thanks.

Thanks for the reply, actually due to workload I do not get much time to go through the documentation in detail. I have seen this method first time so now I will check it. thanks again.

Why not use the ZoomAll method?

out of order cuz I deleted to check viability
