Zoom Target stopped working

Rhino Rhino for Windows
,
1

It seems after the last (?) update the Zoom Target function does not work as it did before. It zooms,

but it zooms in too much. So that the user needs to Zoom out afterwards. This was not the behavior before. It’s quite useless now.

I’ve tried in different files.

Anyone else experiencing the same issue ?

Hi @erik6
Do you mean, that the size of window you drag, after selecting the target, is not respected? I’m not seeing that here, no.

Well,

here it does not work:

zoom target bug

This is a complex file with lots of geometry.

But, yes, it does not respect the rectangle drawn.

Hej Erik -

Does it work as expected in a new file with a simple box?
If so, it’d help a lot if you could post or upload the specific file you are having issues with.

I have at least two files here where it does not work.

It works fine when I open a new file with new geometry.

I’m trying to pinpoint what’s going on.

…. a bit later …

It is actually the DisplayMode that is causing this. The Display Mode I’m using is custom. And it is causing a lot of trouble.

How can I send you the Display Mode only ?

Hej Erik -

I wouldn’t think a display mode contains sensitive information, so attaching the .ini file here would be the most straightforward option. Else, there’s always https://www.rhino3d.com/upload/

I’ve uploaded the .ini file.

The Display mode causing the trouble is:

I can confirm that this problem persists in Rhino 9 WIP as well. Great if it could be solved.
