VGStudio MAX 3.3

Import, Compensate, and Export Specific Points (New in 3.3.3)

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.

Set Additional Target Parameters for Mesh Optimization (New in 3.3.3)

When creating volume meshes, you can now set additional target parameters for mesh optimization, allowing you to control and improve the mesh quality according to specific element quality requirements. This allows you to optimize the tetrahedron quality based on certain element quality criteria when creating high-quality tetrahedral meshes. You can choose one or more of the following criteria: max./min. edge aspect, edge/height aspect, collapse, stretch, shape factor, smallest face corner angle, largest face corner angle, and min. edge size.

Define Entity Sets for Boundary Conditions (New in 3.3.3)

When creating volume meshes, you can now use regions of interest (ROIs) to define entity sets for boundary conditions directly on CT data. This ensures a high degree of geometrical accuracy and reduces possible loss of geometrical information when it is exported to third-party FEM simulation software where load, fixations, or contact can be applied to the defined regions. By relying on the comfortable and familiar ROI tool of VGSTUDIO MAX, you can count on an efficient workflow.

Refined User Interface

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, importing projection images, rendering and navigation in 2D and 3D views, copy & paste actions in the Scene Tree, and autosaving.

Multi-Material Surface Determination

A new mode of the locally adaptive surface determination allows for simultaneous determination of the surfaces of each material within a volume in one go, resulting in one component per material. This makes geometric dimensioning and tolerancing of multi-material objects, e.g., the position of metal pins of a connector relative to the plastic housing, a breeze. It also facilitates the segmentation of multi-material objects.

Multi-ROI Reconstruction

With multi-ROI reconstruction, you can now reconstruct multiple regions that are relevant for your inspection task in one go—manually or automatically. You define these Regions of Interest (ROIs), which can be arbitrarily shaped, in a low resolution volume preview. Multi-ROI reconstruction leads to shorter reconstruction times and lower memory consumption when performing automated inspections of multiple parts in one scan or automated inspections of electronic parts using advanced planar CT.

Data Quality Analysis

Monitor the data quality of your CT scans over time directly in VGSTUDIO MAX—based on the determination of the Modulation Transfer Function (MTF) and the Contrast Discrimination Function (CDF) from a scan of a cylindrical rod according to the ASTM Standard E 1695 “Standard Test Method for Measurement of Computed Tomography (CT) System Performance”. The data quality analysis enables long-term monitoring of the CT scan quality in the same software you use for your measurements and defect analyses. It can now also extract 2D slices from a 3D data set.

The determination is based on examination of the CT image of a uniform disk of material. The MTF is a measure for the sharpness of the edge while the CDF is related to the contrast-to-noise ratio. These functions are key determinants of the structural resolution of the CT system. The variation of the data quality along the axis of the scanned cylindrical rod can be examined by varying the position of the circular cross section for which MTF and CDF are determined.
