Squish crashes Rhino Beta

Squish crashes in (9.0.26237.15343, 2026-08-25).
Crashdump was sent.

Therefore I can’t try _SquishBack.

Thank you again for your feedback. I’ve added your feedback to the previous YT

This one is different.
In the YT SquishBack is the problem, now it’s about Squish.

It works fine in the latest Rhino BETA on my side. I’ve sent you the download link for the latest Rhino BETA via DM. Could you give it a try when you have a moment? Thank you.

In here, (9.0.26244.12303, 01.09.2026), it crashes as described in my initial post.

Hi @Charles,

I’ve logged the crash bug.

Thanks for reporting,

Hi @Charles
I’m working on some squish improvements and I’m looking for samples.
Is the attached solution what you’d expect?

Hi Jess

Yes!

I wonder how you made it, does _Squish work for you in V9?
And how did you get the color in the flat mesh?

It would be nice if _SquishBack was history aware.
Think of changing the flat lines on the arm rest.

Hi Charles,

over the decades I’ve developed many scripts to handle unrolling and squishing. Now I have to support complex workflows and converted some tools to C#. 5 times faster and better handling of UserData, and much more…

The analysis colors were on mesh vertices, which you also get if you extract the analysis mesh. Attached is a version with a texture which shows directional strains more detailed (blue is neutral, cyan represents stretched and magenta compressed).

Transfering geometry could be history aware. But it’s easier to draw directly what you want and flatten after (see attached). 2026-03-16_Squish_B_jM.3dm (8.3 MB)

I’m on Mac these days, and have not tested the new V9 Squisher much. It is in Windows Beta only I think?

Best, Jess
