Paper and cardboard
A deformable sheet of A4 or letter paper, modeled as a very thin shell for office and document handling robots.
Also called A4 paper, letter paper or printer paper.
Thin shell
Delivered as USD for NVIDIA Isaac Sim

A sheet of paper is light, thin and slippery, and it curls when lifted from one edge. We model it as a thin shell with the bending stiffness of office paper and low friction against itself, so a stack slides apart.
Stacks of several sheets are offered for separation tasks.
One USD file per variant, with the render mesh, the simulation geometry and a physics material bound to it. Every value is set and named, so you can open it in NVIDIA Isaac Sim and run your task, or read the numbers into your own solver from the material JSON.

Questions
It ships as USD for NVIDIA Isaac Sim and Newton. We also deliver MJCF for MuJoCo and Genesis, a GLB mesh, and a JSON file with every material value.
Yes. Send us a sample, a drawing or a few photos and we set size, stiffness and friction to match your part.
Choose your simulator, format and variant, then tell us where to send it. We prepare the files and email them to you.
