An Object can be created using the ThreeDFrame:newObject method: 
-- creates a PineObject with the pineapple model at 1, 3, 7
local object = ThreeDFrame:newObject("pineapple", 1, 3, 7)

PineObject
[7]

Known as: model
Type: CollapsedModel
the model that is rendered for this object

PineObject
[8]

Known as: modelSize
Type: number
largest distance of a vertex from the center of the model
