Plasticity: new software

@menno you Should take a peek at this-

Forget Plasticity, Alias, ICEM, and Catia - no software features a physical Zebra surface analysis mode (as I sadly found out today after some idiot managed to mangle the left side of my car in slow motion).

Seems like you have some surface distorsion there that’s not gonna render well

Have you checked the curves?

Hope it’s not a hit and run and insurance covers it

Yeah, the other driver was unskilled in making smooth surface transitions. I will use polygon modelling to pull it all back to shape and save money on repairs!

Nice idea to use a physical zebra cloth. However, it’s already distorted, therefore the reflection on the paint would be still warped even on a perfectly smooth surface.

Well, that ain’t the only damaged area. Lots of vertices to pull all over!

Pffft, class-B bodywork

Class D - deformed/damaged.

Better than class-T: totaled

Hi @giorgio_gurioli

Nice work and great use of both Plasticity and Rhino.
Thanks for posting.

Plasticity 2026.1 was recently released.

Polysplines are apparently a G2 guaranteed variant of subdivision surfaces?

Also… is that 2D illustration export already better than Rhino?

The conversion from SubD to NURBS in Rhino slightly changes the geometry, which results in a distortion in certain spots once the model is exported as IGES or STEP. This is the reason why I don’t use SubD for projects that are intended to enter actual production. The lack of G1 continuity around star-like edge connections (3 or 5 edges meeting together) is also a limiting factor. That’s a known issue of the Catmull–Clark subdivision technique, which seems to be resolved with the Polysplines now. Just wondering if Rhino 9 or 10 could offer a similar technique.

I posted links about “Polysplines” in Polyhedral-Net Splines (aka Polysplines) alt to Catmull-Clark
