There’s no specific category on this forum to share what we could do using ProtoTwin but I’m so excited after building my first larger Onshape model and simulating it that I’m gonna paste it here

PLC logic in TwinCAT
That’s a really fantastic first model! It looks like you’ve grasped all the fundamental concepts. Thanks so much for sharing.
I will create a new category for sharing simulations.
Modified version with some new movements and physics.
Some short video with step by step HOW TO
using Onshape, Prototwin and Twincat…
Maybe to easy for members of this forum
