Viewport in AutoCAD

Question
Viewport in AutoCAD not displaying Model space elements

Answer
There can be a number of causes

Check Layers are turned on within the viewport – (sometimes copy and pasting viewports turns them off!)

Is the Viewport ‘ON’ – (check properties of Viewport – CTRL 1)

Check the MAXACTVP variable – maximum number is 64 – (usually only applies to drawings with lots of Viewports
