Area Variable 1

[dik]

I often use plines to enclose an area for quantity calculations. Is there a system variable for the area within a polyline that I can print directly on the drawing? Is there a *.lsp utility that can do this?

Thanks, Dik

Lots of lisps available to do that.
Here's one by lisp guru Lee Mac:

Another way to accomplish it is to use data extraction, built into autocad. If necessary, you can pull layers, etc, and then insert as a table into the drawing, or export to excel.

If you're just tagging room areas, for instance, I'd say go with the lisp. if you're needing do do some types of calculations on the areas, then that might work better for you.

You can access an object's properties as a "field" also. It's a bit manual to use, but it is dynamic if the object (like a polyline defining an area) changes. For example:
Create Mtext, then right click and "Insert Field", select "Object" under the Field Names, then select the object with the pickbox under Object Type, then select Area (or whatever object property you are interested in: length, elevation, etc.). Regen may be required to update the label if the object changes.

Lisp program works very well, thanks Carl...
