Weird Bug: Can't Zoom Extents on single layout

Rhino Rhino for Windows
,
1

I’ve encountered this bug a couple of times on a large (430MB) file with many layouts (130). At some point a particular layout becomes glitched and Zoom Extents no longer does anything while on that layout. Everything else seems normal, but if I save/close/reopen the file, then zooming works again but the layout size is reset to 8.5x11 inches and the layout name is reset to “Page 19” or whatever number it is. I can change the layout name/size back to what they were and everything is back to normal, but after several hours/days of working in the model, another layout breaks randomly in the same way.

I have a custom script that zooms to the bounding box of the layout, and during the time when Zoom Extents isn’t working, my script correctly calculates the bounding box of the layout (using the original layout size, it hasn’t reset to 8.5x11 yet), but rs.ZoomBoundingBox doesn’t change the view.

Also while it’s broken I can’t change the layout size (but I can change the name).

hi @Measure
pls run _SystemInfo and post back the results.
If you see any pattern when this happens that would be helpful. With only this description, and the fact that it happens seemingly randomly, this will be hard to solve.
I wonder if you can still use _Zoom _Target. In Model view that can often solve issues where zooming stops working as expected.

_Zoom _Target doesn’t do anything.

I ran sc.doc.Views.ActiveView.ActiveViewport.ZoomBoundingBox(box) from a python script, and it returned True but didn’t move the camera.

Also -_ViewportProperties _CameraTarget doesn’t work.
