Accurate
Rest easy with expert tools for expert needs. Full GD&T functionality combined with efficiency-boosting features for complex measurement tasks gives you a precise, complete picture of all object surfaces.

Universal
Enjoy the freedom of a tool that works how you do. It is hardware independent and works natively on voxel, point cloud, mesh, and CAD data.

Innovative
Rely on us to stay ahead of the game so you can, too. Our ongoing new feature rollout addresses the industry's latest challenges.

Supported data types
VGMETROLOGY offers versatile data import options, supporting point clouds and meshes from tactile and optical scanners, as well as voxel data from CT scanners.

Visualisation
Transform your surface data into captivating 3D and 2D visualisations with VGMETROLOGY. Impress and influence peers, decision-makers, and the public with stunning animations—your only limit is your RAM.

Advanced single surface determination
All CT-based metrology relies on accurate surface determination in the voxel model, which reduces measurement uncertainty. Our surface determination minimises measurement uncertainty by being subvoxel-accurate and locally adaptive, enabling the measurement of details smaller than a voxel. It processes grey values based on surrounding voxels for greater accuracy and includes an interval-based mode for high-accuracy, adaptive surface determination in automated environments with variable grey values. 

Measurement tools
VGMETROLOGY offers robust tools to enhance your inspection processes with:

• Dimensional measurement tools: Conduct precise 2D and 3D measurements.
• GD&T support: Use all 17 GD&T callouts, providing detailed analyses and intuitive colour overlays.
• Adaptive Measurement Template: Use for distorted parts, saving time and eliminating manual rework.
• Nominal/actual comparisons: Produce colour-coded visualisations to identify deviations between manufactured parts and reference data quickly.
• Wall thickness analysis: Evaluate part thickness using tailored methods for different geometries, pinpointing areas with insufficient or excessive thickness.

Alignment tools
Alignment is crucial for precise measurement results, facilitating the comparison of nominal and measured dimensions and the analysis of assemblies. VGMETROLOGY features versatile alignment options:

• Point-based alignment: Utilize RPS and 3-2-1 methods for aligning data sets to reference points.
• Surface-based alignment: Perform best-fit alignments with constraints or partial areas, focusing on characteristic features.
• Geometry-based alignment: Sequentially align geometry pairs to imitate physical alignments, decreasing degrees of freedom and fixing remaining degrees with a best fit.
• Tolerance alignment results: Assess the quality of alignment outcomes.
• Custom coordinate systems: Implement custom and local coordinate and datum systems for automated measurement updates during alignment changes.
• Non-rigid alignment: Apply as part of the Manufacturing Geometry Correction Module for flexible adjustments.

Geometry Element Fitting
Extracting geometry elements from scans is the basis for evaluating dimensions and tolerances. VGMETROLOGY enables you to: 

• Extract geometry elements from scans.
• Automatically recognise the type of geometry element using "Smart Expand."
• Control geometry element fitting by border distance, density, angular deviation, fit method (like Gauss or Chebycheff), and constraining to a position or axes.
• Use algorithms verified by PTB and NIST*.
  * PTB- and NIST-verified: This software contains the Volume Graphics Metrology Kernel VGMK 2023.1.0, which passed the PTB test for “Evaluation software based on minimum-zone method for coordinate measuring machines” and the PTB test for “Evaluation software based on least-squares method for coordinate measuring machines” , and which was verified by the NIST “Algorithm Testing and Evaluation Program for Coordinate Measuring Systems”. The test results were obtained under Windows (64 bit).

Reporting
VG software delivers immediate, actionable results, including insightful graphics and detailed reports. Export images, histograms, and data tables in standard formats, create customisable inspection reports, and interface with third-party quality management or statistical process control software. These reporting features are an excellent way to share the extensive information VGMETROLOGY provides about your scanned parts.

Automation
With VGMETROLOGY, work smarter, not harder:

• Streamline inspection and measurement processes through advanced automation and versatile functionality. 
• Automate multi-part inspections using macros and batch processing and facilitate the automatic generation and sharing of measurement templates from CAD files. The "Smart Expand" feature simplifies the identification of canonical geometries with a single click. 
• Define GD&T analyses on CAD or scans and seamlessly transfer measurement plans between different representations. VGMETROLOGY supports efficient patterning of features and measurement plans, including mirroring and creating helical structures for complex shapes like threads and gears. 
• Record macros to automate repetitive tasks and export them for comprehensive automation in VGinLINE.
