Integrated CAD Kernel

  • VGStudio MAX 2.2 includes a CAD kernel as standard feature of the base license. The CAD kernel allows the user to import CAD models including complex component structures as STEP or IGES files. The component structure can be used to segment a CT data set or to determine surfaces of multi-material/multi-component objects. The creation of coordinate measurement templates has been enhanced and accelerated by one-click CAD surface patches picking.

Enhanced 3D Porosity/Inclusion Analysis Tool

  • In VGStudio MAX 2.2, the well-known 3D Porosity/Inclusion Analysis add-on module comes with many enhancements. A new 2.2 enhanced defect detection mode offers improved void and inclusion detection overall and improved detection of voids connected to the outside. The enhanced analysis calculates new parameters, e.g. pore-to-pore distance, sphericity, pore distance to object surface or a user-defined surface. This feature allows you to run a pre-machining test that tells the user if a pore will be inside, outside or on the surface of the object after machining.

 New P 201/VW 50097 Porosity Analysis Option

  • VGStudio MAX 2.2 offers a new optional extension to the Porosity/Inclusion Analysis add-on module: The P 201/VW 50097 defect analysis tool implements industry standard analysis procedures. The new tool therefore allows the users to analyze their parts according to standards defined by the VDG (German Association of Foundry Specialists) or Volkswagen AG. With the help of the new feature, fast non-destructive CT-based defect analysis will be able to replace traditional, destructive and time consuming defect analysis procedures based on micrograph imaging.

Enhanced Coordinate Measurement Module

  • The VGStudio MAX Coordinate Measurement add-on module has already convinced a huge group of professionals in metrology with its intuitive way of use, its performance and approved accuracy. With version 2.2, the Coordinate Measurement module received a large number of improvements and new features, e.g. vector point support, enhanced alignment methods, one-click CAD patch selection, … and many more. The development of many improvements has been driven by our users’ requests, enabling you to make even better use of the unique capabilities of CT than before by using the improved release 2.2 Coordinate Measurement module.

Enhanced Surface Determination

  • VGStudio MAX is already considered to be the industry’s standard, with its high precision surface determination algorithm allowing measurements on CT data to be performed with a minimum of measurement uncertainty. This has been approved by many users and laboratories worldwide. With the new release 2.2, Volume Graphics pushes the limits even further. The improved surface determination algorithm now offers even higher accuracy, and this will lead to improvements especially in high-contrast high-dynamic range CT data, e.g. data resulting from scans of multi-material assemblies. In combination with the new enhanced Coordinate Measuring module, VGStudio MAX 2.2 will set a new reference mark for CT measurement accuracy.

Non-planar Viewing Modes

  • With VGStudio MAX 2.2, 2D views are no longer limited to cuts of the object. You can define shapes along which the 2D views will be generated. This allows you, e.g., to ‘unroll’ cylindrical objects, or to flatten a dented surface, and then scroll into the object following this shape.

Thick Slab Option

  • If you need to follow thin structures, such as wires, within your object, they will usually not be clearly visible within a single slice. The new Thick slab option of VGStudio MAX 2.2 combines consecutive slices into one 2D view. Thick slab can be applied to standard 2D slices as well as the new non-planar views. This allows you, e.g., to conveniently investigate a circuit even on a bent semiconductor chip.

Nominal/Actual Comparison and Wall Thickness Analysis on CAD/Polygonal Data

  • In previous releases, VGStudio MAX has already been supporting measurements of not only voxel data but also geometry data/polygonal mesh data from other coordinate measuring devices imported as STL files. Release 2.2 now also allows Nominal/Actual Comparisons and Wall Thickness Analysis to be performed on CAD/polygonal data.

Sub-voxel Precise Segmentation

  • VGStudio MAX 2.2 now comes with sub-voxel precise segmentation capabilities. Based on high accuracy image processing algorithms, release 2.2 offers tools for more precise separation of individual components of a scanned assembly. Sub-voxel segmentation also helps generating even more precise analysis results, e.g., when measuring a contact surface area between two components or measuring the volume or surface of a component. In combination with the new segmentation capabilities and using CAD model component structures, this new feature will speed-up and enhance segmentation tasks substantially.

Global Tolerancing Capabilities

  • All CT data analysis tools in VGStudio MAX 2.2 now offer tolerancing capabilities, e.g. the Porosity/Inclusion Analysis add-on module allows you to define a maximum allowed pore size, a maximum allowed percentage of porosity, a minimum allowed pore’s distance to the objects surface, etc. In the same way different kind of tolerances can be defined for the Nominal/Actual Comparison, the Wall Thickness Analysis and the new Fibre Orientation tool.


  • Analyzing your object will often involve a variety of properties, such as porosity, GD&T, wall thickness and conformity with a CAD model. With the new evaluation options of VGStudio MAX, you can see at a glance whether your object evaluates to good or bad. You can define constraints for a single analysis, such as maximum diameter of a pore, and even combine them, e.g., to allow for larger pores if wall thickness doesn’t fall below a certain minimum. This new feature makes it possible to use CT for in-line inspection with fully automated good/bad classification.

New CT Reconstruction Modes

  • The VGStudio MAX CT Reconstruction module has proved its high performance and precision in its previous releases. The Version 2.2 CT Reconstruction module now includes support for additional reconstruction and system geometries, e.g. parallel beam, linear detector array and planar CT (Note: Reconstruction for planar CT will be coming soon). In addition, a new so-called Performance mode allows you to reconstruct large volumes at high performance even on limited memory PC hardware.


  • A new Bookmark concept lets you switch easily between different views of your scene. Presenting results to your customers is just a matter of selecting a bookmark. 3D and 2D views, clippings, selection of coordinate systems, background colors and rendering settings will be applied. E.g., you might want to show a Porosity/Inclusion Analysis by setting the part to semi-transparent in front of a dark background in 3D, zooming into the largest defects in 2D, and not displaying all other analyses or metrology elements. The results of a Nominal/Actual comparison will be best shown with an opaque surface, and the 2D views should probably zoom into a critical area. That way, bookmarks help you organizing simple projects with different areas of interest as well as complex projects with multiple objects and/or analyses and measurements.

Further improvements

The VGStudio MAX 2.2 beta version introduces many enhancements for user interface, visualization and data handling, which we are positive will make working with our software even more comfortable for you. Here is a selection of some of those enhancements:

  • Scene Tree: Filter options for name and state of the item in the Scene Tree, e.g., show all items whose name includes ‘cone’, or show all items out of tolerance.
  • Tooldock: Based on the object you select in the Scene Tree, tools which are applicable to this type of object will open automatically. That way, you have all relevant settings easily available, without scrolling the toolbox for relevant tools.
  • 3D rendering and clipping: Enhanced rendering options let you choose how to display the area of a clipped object where a virtual surface is created by the clipping. Also, a new clipping geometry is available: the Clipping Sphere.
  • Meta information in 3D view will display additional information for easier handling of objects:
    – So far, the bounding box around your object showed the outline of your CT data set. If you select a region, a second bounding box will show you in 3D where this region is located.
    – The center of rotation will be displayed, and you can even set the center comfortably using the Navigation cursor.
  • Meta data for CT data sets: Information associated with the physical part or the scan of your part, such as serial number or scanner settings, has no impact on the results you achieve when analyzing the part. However, it is often crucial information which should be available whenever this part is manipulated. VGStudio MAX 2.2 will offer you to edit this information during data import. If available, information which already exists will be displayed.

Upcoming: Fiber Composite Material Analysis Tool

  • The new Fiber Composite Material module will allow the spatial orientation of structures in CT scans, such as glass fibers in composite materials, to be analyzed. The general fiber orientation may be visualized and analyzed in relation to a freely definable plane as a color overlay both in 2D and in 3D. A wide range of statistical evaluations of the analysis results will also be possible with this module.
