I found it hard to resize viewport in the current 2026 version in LAYOUT ( I haven’t used 2025 for as long as I been working with RHINO 3D for a while and it was a bit glitchy for me anyway)
So, recently I found that when I tried to jump form a scale to full size . I have to first double click into the viewport then unclick " Preserve Scale " and then zoom in manually to somewhere close to FULL SIZE. Then click out of the viewport and set FULL SIZE. Otherwise I just end up with an empty viewport. I can unclick "Preserve Scale " previous to click into the viewport , but it is a bit glitchy.
And very often clashes either way.
Not sure if it is a BUG or not. I was wondering if anybody else have problem vit viewport scale and enlarging in 2026.
