Temporarily force EXTMAX and EXTMIN only on a portion of the drawing in model space to permit to zoom all only on this portion.

Temporarily force EXTMAX and EXTMIN only on a portion of the drawing in model space to permit to zoom all only on this portion. In olds CADs ( Personal Designer and CADDS 4X by Computervison) was present.

With a command SetExtFreeze I can give news limits. From this moment I work inside this area. When I have finish i give the command SetExtThaw that restore the original EXTMAX and EXTMIN. There is something that permit to work in this mode?

Thanks in advance.

Hi,

The AutoCAD EXTMIN and EXTMAX are read-only, but you can set the LIMMIN and LIMMAX ones and set the LIMCHECK one to controls whether you can create objects outside these limits.

Added: with .NET, these system variables can be acces via the Database.Limmin, Database.Limmax and Database.Limcheck properties.

You should look into The VIEW command. It lets you save any number of named views that you can recall by name. Each named view can have a user-defined extents.

Thanks for the fast answer.I have try but is not the solution request. I select the view but any tome that I make zoom I have the complete drawing. I want that when I have set the limit the zoom show only inside thsi limit.

There's no way to directly change the EXTMIN/EXTMAX system variables however I do not see the problem with using named views which you can restore transparently while you are drawing using '-VIEW (note the '- prefix)
