GOM Inspect Software Features

Extensive, certified inspection tools

3D inspection - CAD comparison

GOM Inspect contains all evaluation tools for an extensive analysis of parts and components.

GOM Inspect is independently tested and certified by German and American national measurement laboratories (PTB, NIST). The accuracy of the evaluation software is verified by comparing the results obtained from the software with reference results. GOM Inspect has been placed in class 1, the class of the smallest deviations.

Free result viewer

Full-field measuring data allows for an easy understanding of problematic areas and a faster finding of possible solutions. To support the interaction between measurement, analysis, construction and development department, all data created in GOM Inspect Professional and ATOS Professional is bundled in one single file. GOM Inspect is available for customers and colleagues to review the measurement results and to perform further analysis.

All GOM Inspect, GOM Inspect Professional and ATOS Professional data sets are completely inter-compatible with each other.

Latest Feature Highlights


The GOM 3D software contains all standard alignment functions. These include RPS alignment, hierarchical alignment based on geometric elements, alignment in a local coordinate system, using reference points as well as various best-fit methods such as global best-fit and local best-fit. Customers can also use their own specific alignments, e.g. for turbine blades, such as balanced beam or equalized nested.

CAD Comparison

The computed polygon meshes describe free-form surfaces and primitives. These can be verified by comparing surfaces with a technical drawing or directly with a CAD data set. A 3D analysis of surfaces as well as a 2D analysis of sections or points can be implemented in the software. CAD-based generation of primitives such as lines, planes, circles or cylinders is also possible.


The I-Inspect button stands for intelligent inspection and guides operators through the inspection process. I-Inspect suggests suitable measurement principles and inspection criteria to suit the selected element. With I-Inspect, even complex inspection tasks can be implemented quickly and easily.


In contrast to basic measurement analyses, GD&T analysis focuses on the functional aspect of a part. The software conforms to ASME und ISO standards and allows extensive GD&T analysis, including planarity, parallelism and cylindricity, two-point distances, maximum material conditions as well as position tolerance in local and global coordinate systems.

Airfoil Inspection

GOM Inspect combines general inspection functions with application-specific evaluations. Native quality control functionality for the analysis of airfoils and turbine blades include: inspection of profile mean line, profile centroid and profile thickness of turbine blades on the basis of 2D sections. The profile‘s center of gravity, radii and twist can also be calculated.

Curve-Based Inspection

GOM Inspect closes the gap between point-based and surface-based inspection. Full-field digitized data is used to apply construction functions for curves and to visualize their individual properties. Edge curves can, for example, be captured, radii and character lines analyzed and spline curves created. Flush & gap analysis is another element provided in curve-based inspection.

Point-Based Inspection

All evaluation functions can also be used on point clouds. This includes, for example, measurement of distances between individual points and a comparison of points with the CAD model. Construction functions can then be applied to create geometry elements based on several points. This all allows GD&T analysis on the generated elements, including flatness, cylindricity or positional accuracy.


The reporting module enables users to create reports containing snapshots, images, tables, diagrams, text and graphics. The results can be presented and edited in the user interface as well as exported to a PDF document. Custom templates are reusable, and each snapshot stored in a report can be restored in the 3D window.
