System Information
Operating system: Windows 10
Graphics card: GeForce GTX 1070

Blender Version
Broken: 2.92, 3.0 alpha

Short description of error
In this simple model, I cannot zoom my view closer to mesh than I already did. I saved the closest achievable view position in the .blend.
I can reach further close-ups using some more advanced navigation tools, like dolly zoom, but standard zoom won't let me.
The issue is linked to this particular model - if I copy the object (there's only one in the scene) to a new model, the issue is gone.
The model was originally saved in Blender 3.0 alpha, only then in stable 2.92. Could it be the cause of this bug?

Exact steps for others to reproduce the error
Based on the default startup or an attached .blend file:
zoom issue.blend

Hi, thanks for the report. I don't think this is a bug. Few workarounds are also mentioned here: https://docs.blender.org/manual/en/3.1/troubleshooting/3d_view.html#invisible-limit-zooming-in

Will close the report since this this is expected behavior.
(Feel free to reopen if I misunderstood your report)

The doc says: "Use Auto Depth and Zoom to Mouse Position."
I have these settings ON in my Preferences, but it doesn't help at all.
What happens if you use both options? Does it solve the issue for you?

Other workarounds are not enough, while I can't properly use the most important navigation tool.

I don't know how to reopen a closed task here.

The mere fact that you can orbit around means the camera has not reached the defined focal point.

Hello,

I am not entirely sure this is indeed what's mentioned in the manual. To help clarify things, here is my experience : there is indeed a hard zoom limit in the supplied file, something I have not encountered before -but in addition to that there is also some strange interaction between zoom and dolly that I encountered when trying to work around the issue : once the zoom limit is reached (something that in my experience should happen once the camera lens reaches the point of interest, which is not the case here), we can still dolly further with shift+ctrl+mmb. However this dollying pushes the point of orbit further than we would like to (beyond the point of interest), which is expected from a dolly, from there we're again able to orbit around the point of interest if and only if we use "auto depth" (PreferencesInput.use_mouse_depth_navigate). At that point however, trying to zoom or unzoom again results in the view immediately snapping back to the hard limit. So, all in all it seemed a little fishy to me... especially given it's all happening at the centimeter scale, so not especially close to where you see numerical problems creep in.

This is because maximum zoom is derived from grid spacing. I haven't found reason for that.

IMO something like this wouldn't be bad idea

That's true. I've set grid scale to 100 in this model. Switched back to 1 and the issue is gone.

Hello Team,

I am hitting this again. Seems to have re-surfaced. I am running latest daily builds; 3.1.
There was a fix where we could reverse the zoom 'slow down zone' which enabled us to zoom up to parts very close without issue. But that seems gone now or not working.
