Branching facilitates multiple design experiments, and merging designs becomes possible, a feat challenging in traditional systems. Onshape seamlessly integrates release management and approvals, customizable to your workflows. Additionally, the system's connection with ArenaPLM simplifies expansion beyond PDM to PLM.
