How to Add Viewports in CAD


Viewports in AutoCAD are where you draw your models. In Modelspace, the default drawing editor is a viewport. But when working in 3D it is often useful to have more than one viewport open so you can see your model from different angles. This allows you to check your work is correct in three-dimensional space. In Paperspace, multiple viewports allow you to show different aspects of the drawing, if necessary at different scales. These could be the plan, section and elevation of a building, for instance.

Viewports in Modelspace

  • Open AutoCAD. Click View on the Menu bar. From the list that opens, select Viewports, then New Viewports.

  • In the dialog box select the number and format of the viewports you want to show. A preview of how the screen will look is shown in the right pane. Click on each viewport and assign the view you want that viewport to be in from the "Change view to" drop-down below the pane.

  • Click OK and you are returned to the drawing editor which is now divided as selected. To work in a viewport, click inside it. Its border becomes thicker to show it is active. Any changes you make in one viewport are reflected in the others

Viewports in Paperspace

  • With AutoCAD open, switch to a Layout by clicking on one of the Layout tabs. By default the Layout will show one viewport. This can be resized by clicking on its border and dragging it by the blue boxes (grips) at the corners

  • To show multiple viewports, delete the existing viewport. Click View on the Menu bar and pick Viewports, then New Viewports. This opens the same dialog box as before

  • Choose the layout and views you want to show. You can get default 3D views set up by picking 3D from the Setup drop-down. (This applies in Modelspace also.) Click OK when you are finished.

  • When you return to the Layout you must define the area the Viewports will occupy. Left click to place the top left corner, then once more to place the bottom right corner. The multiple viewport is now shown.

  • By double clicking inside each viewport you can adjust the view as necessary. When the view is correct, double click outside the viewport. Now click on each viewports border and select a scale for that viewport.
