Metrology software built by engineers, for engineers

Sitius has been developing coordinate metrology software since 1998. Our main product line, Sitius CMM Suite, is a tightly integrated group of applications for CAD-based dimensional inspection of mechanical parts — running as an Add-In to SOLIDWORKS. Our tools are used by engineers and inspectors in automotive, aerospace, die & mold, and general manufacturing environments. We also offer training, consulting, and software customization services. In addition to Sitius CMM Suite, we develop Opus — a standalone product line for reporting, point analysis, I++ device communication, and laser tracker operation.

CAD-based metrology since 1998

What drives everything we build

01

CAD as the single source of truth

All inspection is referenced to the nominal CAD geometry. No ambiguity, no interpretation errors — just a direct comparison between what was designed and what was made.

02

Tight software integration

Sitius CMM Suite lives inside SOLIDWORKS. No model translation, no round-trips, no data duplication. The inspection environment and the design environment are one.

03

Associativity

Inspection data is linked to the CAD geometry. Engineering changes are detected automatically and can be propagated to existing programs and results.

04

Correctness

Our GD&T engine adheres to ASME Y14.5.1M. We support material condition modifiers, composite tolerances, patterns, and both resolved geometry and surface interpretation.

05

Speed

From formulating the inspection problem to getting a signed-off report — Sitius is built to minimize time at every step of the process.

06

Longevity

We have been doing this since 1998. Our customers rely on tools that are maintained, supported, and continuously improved by people who understand metrology.
