Part numbers that follow your rules.
Keystone is a SolidWorks add-in that gives every part one number and one clear description. The number a part gets on day one is the number it keeps in every drawing after that.
Your rules, built in.
You decide how part numbers work at your company, and Keystone makes sure everyone follows the same rules. It starts by asking what kind of part it is: bought, modified, made in-house, or an assembly. That one answer decides which numbering rules apply. Descriptions are built from shared word lists instead of typed by hand, so the same thing is always described the same way.
Getting a number takes one step. Keystone saves the number, the description, and the file properties together, so you never end up with a number that has no description.
Where numbers are made.
Forge is the part of Keystone that hands out numbers. It isn’t sold on its own yet. Some numbering rules count up in order, and others build the number from details of the part itself. There’s also a practice mode with its own counters, so people can learn without using up real numbers.
In SolidWorks or in a browser.
Keystone works inside SolidWorks 2025 and in a web browser, and both read the same database. An engineer in CAD and a buyer at a desk see the same part with the same number.
It checks before it changes anything.
Before Keystone changes a model, it shows you what will change, what it will skip, and why. If someone typed an equation by hand, Keystone flags it and asks before touching it. Saved part families are locked, and Keystone won’t trust one that’s been edited by hand.
Every release passes its tests before it goes out, and when Keystone can’t do something safely, it tells you so in plain words.
Your files don’t depend on it.
Everything Keystone does is saved right in the SolidWorks file, so your parts still open and rebuild correctly even with Keystone turned off.
Try it with your own parts.
The best way to judge Keystone is with your own part list, not a canned demo. Send us a sample and we’ll tell you honestly whether it’s a good fit.
