Zoom in parallel projection details broken

Version 8 SR15

I have a file that will not zoom properly in details when displayed in parallel projection “isometric” views. It will zoom with the mouse wheel, or zoom dynamic button, then jump back to previous. Changing projection to perspective allows zooming but then resetting the projection back to parallel the zoom jumps back out again. Zooming extents or selected first does not help.

Zooming of planar views in the details works correctly.

Hi Eric -

I’m not seeing that here in a quick test. Does the “I have a file” part mean that this is limited to that file?
This is my test file: Isometric Detail.3dm (2.0 MB)

Also, please post the output from the SystemInfo command.

Hi wim,

So far limited to this file, but the unique setup of projection mode, model extents and orientation is also limited. Let me know if you would want to have the file.

Eric

Hi Eric -

Yes, please. You can upload it from Rhino Accounts.
Make sure to add a link to this topic in the comments field on that page.
