Tessera.
Tessera manages engineering projects around two things: a reusable pattern library and one search across every project and every revision. Everything else — function data, manufacturing model, PLC, documents — is a module that plugs into the same core.
One catalog. One index. Every project.
Every project.
One place.
Projects, revisions and the record of where each solution is already deployed — the answer to “everywhere we use this” stops living in people’s heads.
Solve it once.
Reuse it everywhere.
A pattern carries its own typed variables, enumerations and validation rules. Publish it and the version freezes — so every instance knows exactly which definition it was built against.
Recognize it.
Then confirm it.
Drawings, workbooks and libraries go in; recognized patterns come out. Deterministic import and AI mining share one contract — and every match is a proposal a human confirms before it counts.
What is where.
And how it’s built.
Slice by pattern, article, address or function path — across every project and every revision. A hit is not a text match but an entry point: click through and the real relations answer how.
One core.
Many modules.
Function data, manufacturing model, PLC and safety, generated documents — each module feeds the same catalog and the same index. Turn one on and the search simply gets deeper.
