Issue:
We are unable to double-click a viewport to make it active.
Cause:
This can happen when using MAXACTVP and having it set to a number smaller than the number of viewports within the drawing.
Solution:
There are a couple of ways to work around this problem.
- Toggle the properties of the viewport off/on manually.
- Create a toolbar button to turn it on.
Toggling the ViewPort:
Select the Viewport and bring up the Properties Palette.
Under the “Misc” section set the On value to No or Yes, you may need to go back and forth a couple of times.
Done.
Using a Toolbar button to Toggle the setting On.
Autodesk has an article on how to add a new toolbar button:
https://www.autodesk.com/support/technical/article/caas/sfdcarticles/sfdcarticles/Adding-new-toolbar-buttons.html
I will use the following settings for my new toolbar button.
- Name: ViewportOn
- Description: Turns on the viewport
- Macro : ^C^C_mview on \;
For the toolbar image, click the one you want from the list or you can make your own.
Click Apply!
Now to get the button onto the Viewport toolbar.
Drag & drop the new icon onto the Viewports toolbar (or toolbar of your choice).
Click Apply & Ok.
Make sure you turn on the Viewport toolbar and now when you click the new toolbar button, select the viewport you want turned on.
When I click the lightbulb toolbar button I created, the command line now shows:
I click on the viewport.
And there it is!
This one will allow you to click the viewport then the toolbar button.

^C^C_MVIEW;on;_p;;
Lastly, you could reset MAXACTVP to a higher number. The default is 64.
Note: this may affect performance.
