Version Control & Team Collaboration Disasters

Onshape is real-time multiplayer, which is a gift and a hazard. The classic disaster: ten students editing one Part Studio at once, someone deletes a feature mid-edit, and an afternoon of work evaporates. Here is how to keep a team document sane.

Problem: simultaneous live edits clobber each other. Onshape doesn't lock features, so two people editing the same sketch fight over it. Fix: assign ownership — one student per Part Studio per session. Use the presence indicators (you can see who is in a tab) to avoid collisions, and split subsystems into separate tabs/studios so people work in parallel without overlap.

Problem: you need to try a risky redesign without breaking the working model. Fix: create a Branch from a Version. Branches are isolated; the main design keeps working while you experiment. When the branch is good, merge it back. This is the safe way to prototype a 'what if the gearbox were a different ratio' change.

Problem: 'who broke the drivebase?' / can't get back to a known-good state. Fix: create Versions at every milestone (e.g., 'Drivebase frozen for manufacturing'). Versions are immutable snapshots; you can always restore or branch from one. Pair this with the version-locked derive workflow so subsystems reference a frozen layout, not a moving target.

Problem: the shop manufactured an out-of-date part. Fix: use release management to mark a part as approved-for-manufacture, and only cut parts from a named version or release — never from live 'tip' geometry that a teammate might be editing right now.

Problem: an edit went wrong and you want it gone. Onshape's full edit history lets you see every change and restore to any prior point. Use the version/history graph to compare or roll back.

A healthy team workflow: (1) One layout document, versioned at milestones. (2) Subsystems in their own Part Studios with assigned owners. (3) Risky work happens on branches. (4) Versions cut at every freeze. (5) Manufacturing pulls only from releases/versions. (6) Design reviews check that what is being cut matches the released version. This turns Onshape's collaboration from a liability into the team's biggest speed advantage during build season.
