DrawingElement
DrawingElement =
ComponentDefinition|ComponentInstance|ConstructionLine|ConstructionPoint|DimensionLinear|DimensionRadial|Edge|Face|Group|ImageEntity|SectionPlane|Snap|Text
A union of all entity types that can physically exist in the modeling space.
This is the base type for anything visible in a SketchUp model — edges,
faces, groups, component instances, construction geometry, dimensions, text,
images, and section planes. When you call model.entities.get(), the
returned array contains DrawingElement objects. Each member of this union is
a read-only snapshot of that entity at the time it was fetched.
You can narrow a DrawingElement to a specific type by checking its type
property (a numeric enum from SketchupEntityEnum), or by fetching
only the types you need with the filterBy option.
