What is version control for CAD?
Version control let software teams stop overwriting each other and start experimenting safely. Here's what the same idea looks like for engineering drawings. Branch, merge, and restore, without the file chaos.

If you've ever opened a folder and found bracket.dwg, bracket_v2.dwg, and
bracket_FINAL_use-this.dwg sitting side by side, you already understand the
problem version control solves. You just haven't had the tool that solves it for
drawings.
Software teams fixed this decades ago. Version control is the system that records every change to a project, lets people work in parallel without clobbering each other, and makes it safe to try something risky because you can always go back. BranchCAD brings that same model to 2D CAD, built into the drawing surface, not bolted on as a file-naming convention.
The three moves: branch, merge, restore
Version control for CAD comes down to three operations you can actually trust:
- Branch a drawing to try a change (a new bracket profile, a revised hole pattern) without touching the original. If it doesn't work, you throw the branch away and nothing is lost.
- Merge the branch back when the change is right, so the improvement lands on the main drawing in one deliberate step.
- Restore any earlier version with one click. Every edit is tracked, so "go back to how it was on Tuesday" is a button, not an archaeology project.
The point isn't the Git vocabulary. It's that experimenting stops being scary. When going back is free, going forward gets bold.
A history you can read
Because every change is recorded, you always know who changed what, and when. Instead of a pile of files, you get a clean log, much like a commit history:
* a4f9c1 2026-06-24 Tighten fillet radius on mount tab (Sarah)
* 7b20de 2026-06-23 Add two M4 mounting holes (Hamish)
* 1c88a0 2026-06-21 Initial bracket profile (John)
That readability is the difference between a drawing you can maintain for years and a folder nobody dares to touch.
Files vs. versions, side by side
| The old way | With version control |
|---|---|
part_v7_final.dwg emailed around | One drawing, many tracked versions |
| "Which copy is current?" | The current version is always obvious |
| Overwrite and pray | Branch, try it, merge if it's right |
| Lost work when someone saves over you | One-click restore to any point |
Where this fits in BranchCAD
Version history and restore are built in from the Free plan. You get 30 days of history, with full history kept forever on paid plans. Branching and advanced visual diff arrive on Pro. And because it's all in the browser, your team can be on the same drawing in real time while every edit is versioned behind the scenes.
If you've been managing drawing revisions by hand, this is the part that gives you the afternoon back. See what's included on each plan, or just open the editor and branch your first drawing.
