What is GOM Inspect

GOM Inspect is a software for analyzing 3D measuring data from fringe projection or laser scanners, coordinate measurement machines (CMM) and other measuring systems. The GOM software is used in product development, quality control and production.

Polygon Mesh

3D meshes for parts and components are calculated from 3D point clouds for visualization, simulation, reverse engineering and CAD comparison. The precise polygon meshes can be exported to a number of standard formats such as STL, G3D, JT Open, ASCII and PLY.

3D Mesh Processing

Polygon meshes can be smoothed, thinned and refined. In addition, holes in the mesh can be filled and curvatures can be extracted. The mesh is processed using curvature-based algorithms and tolerances. The software provides the user with a live preview of each processing step. Furthermore, a golden mesh can be determined by finding the best mesh or calculating an average mesh.

CAD / Measurement Plan Import

Neutral CAD formats such as IGES, JT Open and STEP, as well as native formats like CATIA, NX, Solidworks and Pro/E, can be imported into GOM Inspect Professional at no extra cost. In addition, measurement plans in CSV, DMI, ASCII, IPP and FTA data formats can be imported as the basis for dimensioning and inspection. The individual data formats are imported via drag & drop and are automatically identified and assigned by the software.

Parametric Inspection

With GOM‘s parametric concept, each individual element retains its creation path within the software structure. All actions and evaluation steps are fully traceable and interlinked. Individual elements can be modified and adjusted at any time, and a one-button solution updates all dependent elements automatically after changes have been made.


The exact creation parameters and the selection of measurements and points for each element can be traced to source, verified, and, where necessarily, adjusted. The traceability of all measurement results is guaranteed. This property in the parametric concept plays a vital role in the reliability of the quality control process.

Teaching by Doing

With Teaching by Doing, any completed evaluation can easily be applied to two or more parts. Thanks to the parametric design, the software automatically stores each individual inspection step. All evaluation steps can be operated without scripting, previous planning or user intervention, so that no time is spent on programming.


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.

GD&T Analysis

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.

Trend, SPC and Deformation Analysis

The underlying parametric concept of the GOM software makes it possible to implement trend analysis for multiple evaluations, for example, in statistical process control (SPC) or for deformation analysis. This enables full-field evaluation of several parts or stages within a single project and offers functionalities for determining statistical analysis values such as Cp, Cpk, Pp, Ppk, Min, Max, Avg and Sigma.

Airfoil Inspection

GOM Inspect Professional 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 Professional 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.

Import of Volume Data

GOM Inspect can be directly used for visualizing and evaluating scanned volume models. Due to the new import function, volume data generated by computer tomographs can be immediately imported into the software. In the past, this process required an intermediate step with an extra software. Now, users can import and analyze volume data in common formats (.vgi, .vgl, .pcr, .exv, .rek) or as raw data efficiently and at a reasonable price. Furthermore, the software allows the import of various different materials from the scanned object as separate surface meshes.

Surface Defect Map

The surface defect map enhances the surface inspection. The new function detects small defects based on meshes and displays them in the color plot. For example, dents and sink marks become visible. To visualize and quantify local bulges and depressions, the surface defect map directly works on meshes. The software computes a theoretical surface for more realistic results. By comparing the nominal and actual surface inspection, the new feature allows the compensation of the global curvatures.

Virtual Measuring Room (VMR)

The VMR is a virtual, yet functional representation of the real world. The VMR is a fully integrated solution, allowing for the complete reproduction of automated measurement processes. Combining the parametric inspection processes offered by GOM Inspect Professional, the VMR enables the execution of automated measurements: import of measurement plans, offline and online programming, 3D measurement simulation, collision control, safety, data capturing, inspection and reporting.


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.

Free Viewer for 3D Scan Data, Measuring Reports and CAD Data

Full-field measuring data allow a fast understanding and correction of problematic areas on the component. All data created in GOM Inspect Professional and ATOS Professional is bundled in one single file. The free GOM Inspect software provides access to the measurement results. This leads to an improved interaction between the departments responsible for measurement, analysis, design and development. Measuring data can be discussed and decisions can be taken faster.

Certified Software

In order to ensure precise measurement accuracy, GOM Inspect software packages have been tested and certified by PTB and NIST institutions. The accuracy of the evaluation software is tested by comparing the results from the software with reference results. The GOM software has been placed in Category 1, the category with the smallest measurement deviations.
