// get a list of all mesh objects

// compute the bounding box

// copy values into variables for readability
float $xmin = $boundingBox[0];

// compute dimensions, and convert from cm to meters
vector $dim = <<($xmax - $xmin) / 100.0, ($ymax - $ymin) / 100.0, ($zmax - $zmin) / 100.0>>;

// print result
