Modelspace viewport object is the main drawing window through which most entities are created and edited. It shows a view of 3D model space. Depending on whether the viewport exists on Modelspace or Paperspace they are defined as modelspace viewport object . There can only one modelspace viewport exist in a drawing. Modelspace viewport are always created by hsCADView on a Layout named "Model" when a new drawing is created.
