What's New in VGMETROLOGY

The Manufacturing Geometry Correction Module now lets you import, compensate, and export specific points. By using specific points instead of arbitrary fit points, you can automatically update parametric constructions in CAD systems based on these specific points.

A new, more streamlined user interface in all applications is the most obvious change in version 3.3. A better visibility of symbols and texts makes any task in the software even more straightforward.

Performance Enhancements

When using version 3.3, you will immediately realize how much more responsive the application feels and how much faster some processes are. The performance enhancements affect everyday tasks such as the opening of very large .vgl files, rendering and navigation in 2D and 3D views, copy & paste actions in the Scene Tree, and autosaving.

The creation of golden surfaces (i.e., average surfaces) for multiple identical volume objects now includes the option for maximum and minimum material surfaces. It saves you time when tolerancing multiple identical parts, e.g., from a casting or injection molding tool with multiple identical nests, by tolerancing only the minimum and maximum surface. If these surfaces fulfill all tolerances, this also applies to the individual components.

By calculating the centroid, i.e., the geometrical center of an ROI, you can reduce the time required for the assessment of potential mechanical imbalances, e.g., in rotating parts. The calculation can be automated via macros and the position of the resulting centroid point can be toleranced.

To centrally store CT results in quality management or statistical process control software, you can now export the detailed results of dimensional measurements, position & form tolerancing, and the global results of analyses (nominal/actual comparison, wall thickness analysis, porosity/inclusion analysis, fiber composite material analysis) using the widely used Q-DAS data exchange format.

The Wall Thickness Analysis Module is now included in VGMETROLOGY and VGMETROLOGY ES at no extra charge, enabling you to localize insufficient or excessive wall thickness or gap width in cast, injection molded, or 3D printed components with complex internal geometries.

Reportable bookmarks make creating reports of top-level objects and analyses in automation scenarios more flexible and highly reproducible. Bookmarks can now be referenced by volumes and other top-level objects, analyses, and measurement plans and are included in the .vgrf format as well as in the associated reports in Microsoft Excel (requires Microsoft Excel) and reports in the .pdf format. Reportable bookmarks offer a combination of high flexibility—because arbitrary 2D and 3D views can be stored as bookmarks—and high reproducibility for automated setups—because bookmarks can be stored as templates which can be used in automated workflows.

The input data (analyses, references objects) of job steps can now depend on meta information. When inspecting automatically, e.g., injection molded or cast components, the software can apply the right reference objects and analyses for the part depending on the meta information, such as the cavity number.

• The creation of CAD files from geometry elements is now macro recordable.
• The export of transformations is now macro recordable.

• New option to create CAD elements from lines, circles, freeform lines, and freeform surfaces.

• Project-specific nominal and tolerance values of geometric dimensions can now be imported as a .csv table and assigned to the features based on the feature names. This saves time compared to the manual entry of the tolerance and nominal values, since the tables are typically available from the design engineer or a ballooning software. (new in 3.3.1)

• When tolerancing freeform surfaces, deviations between nominal and actual surface profiles can now be visualized in 2D and 3D views via a nominal/actual comparison, allowing for a detailed interpretation of the tolerancing result. The positions of the minimum and maximum deviations can be copied into the nominal/ actual comparison and displayed as annotations.

• The object meta information now includes the fields production time and cavity number, improving traceability and filtering options, e.g., in reports or when exporting it in the Q-DAS data exchange format.
• You can now display meta information in text overlays in 2D and 3D windows, both the built-in meta information fields and custom fields from the component, the scan, or the scanner manufacturer section. This increases the traceability of screenshots and, when viewing several similar scans in one scene, better indicates which scan is currently displayed and analyzed.
• To analyze multiple files in the same way, VGinLINE jobs in VGSTUDIO MAX now support multiple input files which will be processed in sequence. This way, batch playback—which previously only worked with macros—is now also available for the more powerful VGinLINE jobs in VGSTUDIO MAX. Results can either be stored in the same folder or individual subfolders.
