    Default Weight and Centroid of Solids and Blocks (with solids in them)

    It always amazes me what gets left out of AutoCAD.

    Like we have materials, but we don't have densities.

    490 pcf for steel for example.

    Sometimes it is good to know how much something weighs... right?

    Attached you will find a lisp routine called "centroid" and a sample drawing called centroidtest.

    If any of you are interested, could you CRASH test it for me?

    You can add densities to material objects in the materials table.

    If you select items (blocks or solids) it will find the total weight and the centroid.

    P=

    PS.. Found a minor bug, and re-uploaded the zip file.

    No time to test that, but one gotcha: make sure it works on objects waaaaay out in WCS space.

    AutoCAD is not accurate far from the origin (No double precision)
