Don't just measure,
make sense of it

Sitius delivers CAD-based metrology software for dimensional inspection of mechanical parts. Tight SOLIDWORKS integration, full GD&T analysis, and clear reporting — built for engineers who need answers, not just numbers.

Why Sitius

Built for precision. Designed for engineers.

Sitius CMM Suite is a tightly integrated group of products for CAD-based dimensional inspection — from off-line CMM programming to point-to-CAD comparison and GD&T reporting.

CAD-Based Inspection

Unambiguous model representation eliminates interpretation errors across prismatic and free-form geometry.

SOLIDWORKS Integration

Work directly inside SOLIDWORKS — no model translation, no data duplication, no round-trip errors.

Associative Inspection

Inspection data is stored with and linked to the CAD model. Engineering changes are detected and propagated automatically.

Off-line CMM Programming

Program your CMM at the CAD workstation with Metrium — freeing the machine for unattended, high-speed measurement.

Full GD&T Analysis

Adheres to ASME Y14.5.1M. Supports material condition modifiers, composite tolerances, patterns, and surface interpretation.

Wide Device Support

Ingest point data from motorized CMMs, manual CMMs, articulating arms, laser trackers, optical comparators, and scanners.

Sitius CMM Suite for SOLIDWORKS

One environment for your entire inspection workflow

Integrated inside SOLIDWORKS

Programs, point data, GD&T database, results, and reports are all stored with the part — engineering changes detected and propagated automatically.

Off-line CMM Programming

Metrium programs DCC CMMs at the CAD workstation with simulation and collision detection, enabling unattended high-speed measurement.

Point-to-CAD Comparison

Sitius PV compares collected point data to nominal CAD geometry, evaluates geometric tolerances, performs best-fit analysis, and generates reports.

On-line Inspection

The I++ DME Client communicates directly with I++ capable CMMs for on-line inspection of mechanical parts.

Opus

Standalone tools for reporting, analysis, and device control

When you need metrology outside SOLIDWORKS

Opus is a standalone product line for reporting, point analysis, I++ device communication, and laser tracker operation.

Opus Viewer

View and share inspection results without a full license. Available in free and paid editions.

SPV

Standalone point-to-CAD comparison and GD&T analysis outside of SOLIDWORKS.

Laser Tracker Support

Operate and collect data from laser trackers directly through the Opus environment.
