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. 

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.

What's new in 2024.2
Enhanced modifier selection for linear sizes

You can now measure linear sizes that require the use of rank order modifiers (for example, for the calculation of an average size) or the use of the ACS (arbitrary cross-section) modifier for the calculation of size measurements in any cross section.

Measurement tasks according to ISO 14405-1 that require the use of these modifiers can now be easily performed by choosing the appropriate modifier symbols in the "Linear sizes" dialog.

Histogram and statistics for linear sizes

When you use linear size modifiers such as LP (local two-point size) or ACS (arbitrary cross-section), many sizes will be calculated at a time. While you will usually tolerance only a single size value (e.g., the maximum, SX, or the minimum, SN), much more information about the measurement itself is now available: A new tab in the "Linear sizes" dialog will show you a histogram of all calculated sizes as well as a number of statistical values, allowing for an intuitive overview of the size distribution and overall tolerance state of the measured element. 

PMI import options for linear sizes

The advanced CAD import with PMI is now capable of interpreting modifier symbols of linear sizes and automatically creating the appropriate linear size measurements during import.

Additional import options allow you to choose the default modifier symbols to be used when linear sizes without specific modifier symbols are found in the PMI data.

New 2D regular elements for circles and parallel lines

You can now create regular elements for circles and two parallel opposing lines in a 2D view and use them for linear size measurements and various geometric tolerances. This is especially useful when you have to measure linear sizes in a specific cross section (SCS) of an element.

Reporting and Traceability

Customizable text color in reports
We further enhanced the customizability of reports: you can now set arbitrary colors for all textual layout elements to highlight certain results or custom text.

Exporting multiple movies or image stacks of an inspected component at a time
The new queuing function of the "Save movie/image stack" dialog allows you to parameterize and queue multiple export jobs, and subsequently export all image stacks or movies at a time without further interaction.

This will streamline your export process considerably, as you will no longer have to wait for the completion of each individual export job before being able to parameterize and start the next one.

Explanatory texts for the “Bookmark” and “Automation” tools

The new explanatory texts will make it easier for users to understand the purpose and functionality of both the "Bookmark" and the "Automation" tool and improve the accessibility of the software.

Automated computation of deformation fields

The computation of deformation fields can now be automated via macro. This way, you can save time in your daily work when using deformation fields for the “Morph mesh” or the "Compensation mesh" function, or for adaptive ROIs or coordinate measurement templates.

What's new in 2024.1
Interactive HTML reports

Sharing comprehensive inspection results just became even easier. The new HTML format is an all-in-one solution that also supports interactive elements, like part or result 3D views. These self-contained documents eliminate the need for a separate viewer application and are easily accessible with any Chromium-based browser like Edge or Chrome.

Linear sizes now available

Simplify standard conform measurements with direct support for modifier symbols. These include two-point measurements [LP], the envelope requirement (E), and global modifier symbols like [GG], empowering easy evaluations for many size features. 

Automation: Improved project organization

Now, projects loaded during batch processing won't automatically clutter your recent files list. This ensures your manually worked-on projects remain readily accessible. However, if you prefer the previous setup, don't worry — you can always change this setting in Preferences.

Improvements for Erode/dilate ROI sphere mode

You can now specify the sphere radius in length units, even on anisotropic data sets. Enjoy significantly boosted performance, reaching computation speeds that are more than 50 times faster — specifically noticeable when utilizing larger radius values.

File I/O

PNG format for streamlined image stack import and export
You can now bypass the need for additional file conversions when using PNG as a storage or data exchange format. Enjoy a faster workflow for importing and exporting your volume data.

New DICONDE export

Volume data can now also be exported in the DICONDE format, which includes the existing tags. For volumes that were not imported from DICONDE, the necessary tags are created on the fly.

Preserve metadata between volumes

In the past, transferring metainformation like DICONDE tags between different volumes in a scene was impossible. With this feature, you can now easily move this essential information, even when creating entirely new volumes from initial scan results. This enhancement ensures traceability is maintained throughout your process, keeping your work consistent and structured.

System requirements

Read the basic requirements below or download the PDF for the complete system requirements for VGMETROLOGY.

Operating system

Windows 10* Enterprise 64-bit 
Windows 10* Professional 64-bit
Windows 11 Enterprise 64-bit 
Windows 11 Professional 64-bit 
 

*VGMETROLOGY will no longer support Windows 10 as of version 2025.3

Processor

Minimum: x86-64 CPU with instruction set SSE 4.1. ARM processors are not supported.

Recommended: Performant Intel or AMD multi-core processors, e.g., Intel® Core™ i7 or i9 or Xeon® Gold processors with 3 GHz or higher.

RAM

Minimum: 

VGMETROLOGY requires a minimum of 4 GB of free memory. However, the actual free main memory needed for creating or loading a complete project might be significantly higher since it depends on the data set size, the number of objects per project, the analyses to be performed, and whether the import function will be used. 

Recommended for professional use: 

  • If your tasks include importing CT data sets without advanced surface determination, the free main memory should at least be 2.5 times the size of the data set to be imported. If your computer has less free main memory, the import will be performed block-wise, which, however, will reduce performance. Be aware that block-wise processing during import is not available when the Filter components (particles) or Filter voids option is used.
  • If your CT data sets already have an advanced surface determination (automatically from prior import into VGMETROLOGY or prior processing with VGSTUDIO MAX), use File > Open instead of File > Import. Importing CT data sets is not available in VGMETROLOGY ES or VGMETROLOGY VIEWER. The amount of data when opening a project is usually relatively small and can be handled by any state-of-the-art off-the-shelf computer. However, if a project contains many data sets, the memory requirements will be increased accordingly.
  • Typical for industrial use is a PC with at least 64 (for one data set) to 512 GB RAM (for multiple data sets), depending on your workflow. Higher RAM clock speeds are recommended.
