Select Objects Smaller Than

[user_deleted]

want to select all objects smaller than a certain size. this code runs, but doesn't do what I want. selects objects in a seemingly random fashion.
Some suspicisions:
- maybe bounding box is not returned in world space?
- maybe (($sizeX + $sizeY + $sizeZ) / 3) is not right.

CODE
float $boxSize;
float $sizeX;
float $sizeY;
float $sizeZ;
float $size;
int $i = "0";

string $node;
string $allNodes[];
string $newNodes[];

$allNodes = selectedNodes;

for ($node in $allNodes)
{
//$node = $allNodes[0];

$sizeX = getAttr ($node + ".boundingBoxSizeX");
$sizeY = getAttr ($node + ".boundingBoxSizeY");
$sizeZ = getAttr ($node + ".boundingBoxSizeZ");

$size = (($sizeX + $sizeY + $sizeZ) / 3);
print ("size: " + $size);

    if ($size < 3)
    {
    $newNodes[$i] = $node; $i++;
    }

}

select -cl;
select $newNodes;

you can directly query the bounding box or surface area of a polygon mesh using polyEvaluate:

CODE
polyEvaluate -query -boundingBox;
polyEvaluate -query -worldArea;

also try:

CODE
computePolysetVolume;

you want the volume of the boundingbox?
what about just x*y*z?

for instance: an object that has the size of 1 1 2. Just a unitcube double stretched to z. with your formula wound mean (1+1+2)/3 = 1.33m
