Modelspace Viewport Object is the main drawing window through which most of entities are created and edited. It shows a view of 3D model space. To facilitate viewing of drawing through multiple viewports in Modelspace, utilizes pre-set multiple viewports through Pre-configured Viewport Tool and Divide Viewport Tool. Depending on whether the viewport exists on Modelspace or Paperspace they are defined as Modelspace viewport object and Paperspace viewport entity.. There can only one Modelspace Viewport exist in a drawing. Modelspace Viewport are always created by on a layout named "Model" when a new drawing is created.
