Make a Zoomed Viewport Bubble- AutoCAD Tutorial
This article focusses on AutoCAD tutorial to create a zoomed viewport bubble in AutoCAD. It is a cool graphic effect to display both context and an enlarged detail of a specific area in the drawing.
So, today I was asked, how to create a viewport within a viewport AutoCAD. He was trying to Insert viewport over an existing viewport, to show small viewport within the big viewport.
This post will teach you how to wipeout behind a viewport in AutoCAD. You will learn how to use viewport clip to maks the viewport. In other words a viewport in another viewport.
The enlarged viewport bubble is a cool graphic effect that shows both context and detail simultaneously. In this tutorial, you need two nested viewports to achieve this effect—one rectangular and one circular. The trick is, the objects in the rectangular viewport must not appear within the overlapping circular viewport.
This AutoCAD tutorial explains about overlapping viewports by using viewport AutoCAD command.

Step by Step AutoCAD Tutorial – Overlaying Viewports
You can achieve this sophisticated effect only by creating viewports from objects, and even then, the objects must be unique. To see how it’s done, follow along:
- Create two layers to hold the viewports. Ultimately, one layer will remain on, showing the circular viewport, and the other will be turned off to hide the rectangular viewport frame. For now, create two layers called Viewport-A and Viewport-B, and leave them both on.
- Create a layout and add a title block. Draw a rectangular polyline to represent the outer viewport.
- Draw a circle somewhere inside the rectangle you drew in the previous step. This is destined to become the enlarged bubble.
- Copy and paste the circle in place. This will have two overlying circles.
- Type the REGION command in the command line, and select the first rectangle and any one of both circles.
- SUBTRACT the smaller region from the larger by selecting the rectangular region first, pressing Enter, and then selecting the circular region. You’re left with one region and one circle.
- Convert the region into a viewport by using MVIEW’s Object option. Put this viewport on layer Viewport-A, and then turn it off. If you’ve done it right, the drawing will show up in the rectangular area but won’t appear within the circle. So far, so good. 8. Set layer Viewport-B current so that the next viewport will be on this layer. Convert the remaining ring into a viewport.
Pan and zoom as necessary to create an enlarged plan within the bubble. Voila!
