double ObjDim (object obj, channel chan )

Return Value: Object's dimension in the given channel

Arguments:

This function determines the dimensions of a mesh item. To get the dimensions in world coordinates use wxpos, wypos and wzpos.

Example:

    BoundingBox_Width
    |_ ObjDim( Head, xpos )

    BoundingBox_Height
    |_ ObjDim( Head, ypos )

    BoundingBox_Depth
    |_ ObjDim( Head, zpos )

These three expressions get the bounding box of an object in local coordinates.
