    Default Drawing Extents

    I know you can get the bounding box of a block which will give its overall size but how do you go about this when you do not know the biggest block in the first place?

    What I want to do is to determine the extents to which a drawing occupies. I basically need to know how wide and how long the drawing is.

    There is no common block, ie a title block (or similar), that I can use the bounding box method on so I need to look into indivuidual elements of the drawing itself.

    Has anyone done anything similar?

    Thanks

    Check the EXTMIN and EXTMAX system variables. Be aware that you may need to regen and/or zoom extents first.

    When I use extmax and extmin is usually set the units to decimal and eight places. The z values usually come as a suprise to many of the users I show this trick to. It is supposed to be zero. Often, it is not.
