Virtual implementation on Onshape software refers to creating and testing 3D models of mechanical designs in a fully digital environment without needing physical prototypes. Here's a brief explanation:

• 3D Modeling: Onshape allows you to design parts and assemblies in 3D using parametric modeling tools.
  
  

• Simulation: You can test movements, fit, and function of parts using motion studies and interference checks.

• Collaboration: Teams can work together in real time on the same model from anywhere, since Onshape is cloud-based.

• Version Control: It automatically tracks changes, making it easy to revert or review design history.

• Use Case: Ideal for testing mechanisms like gears, linkages, or cams virtually before physical manufacturing.
