I have a question while executing the viewport command.

Hello.
I created two viewports using the vports command in an AutoCAD model.
When I zoom in one of the viewports, the other viewport zooms in the same way.

That is, the two viewports zoom at the same time.
Originally, when I zoom in one viewport, the zoom screen should not be executed in the other viewport...
Why is that? Why does this symptom occur? I am curious.

Haven't you ever had this experience?

Can you post a small drawing file containing two Viewports that behave in this way?

@nychoe1  hi,

Make sure UCSFOLLOW is set to 0 in each viewport - does that solve the issue?

@nychoe1 .... and get in the habit of locking your viewports too when you are not in need to change the ZOOM of the content.

I solved it.

I turned it off because the third-party program had a zoom link function.

Thank you.
