erratic zooming to extents after setting a view to a named view

[Ross_S1]

In one of my files, I have many saved views (20 to 30). On some or all of them, when I select a named view, the viewport will zoom in to the desired view, but almost instantly zoom to extents. Any ideas what can cause this?

I am using Civil 3D 2024 with 2024.4 update.

I have done the following and got no results.

I restarted the program.

I ran recover on the file. No errors showed up.

I turned object snap off.

In a copy of the file, I deleted most of the views, to see if the number of them was causing the issue.

I had a coworker open the file on his computer (with version 2023). He got the same results.

Thank you in advance for the input.

Here is one more component of the situation. When I have two views open on the project, I'm working in one view and switch to the other, the first view reverts to zoom extents.

Can you share the drawing?  I would like to test this out, but I don't have drawings with that many views.

Thanks.

Here is a copy of the file, that has been modified (not in original location, etc). This one doesn't have the large number of views in it as previously mentioned, but it still has the problem at hand.

Hi Ross,

Thanks for sharing the file. One thing you might want to try is setting the UCSFOLLOW system variable to 0. This setting controls how viewports respond to changes in the User Coordinate System (UCS).

The UCSFOLLOW setting is saved separately for each viewport. When UCSFOLLOW is turned on (1), a plan view is generated in the viewport whenever you switch to a different UCS. If it’s set to 0, changing the UCS won’t affect the current view.

Here’s how to change the setting:

1. Type UCSFOLLOW in the command line.
2. Set the value to 0.

Link to documentation.

That was what I needed. UCS Follow set to zero kept my view at the zoom that I had it set to when clicked into a different viewport. Thank you, Hopefully this can help someone else.
