This creates the "heat map" showing where the part is too thick (positive deviation) or too thin (negative deviation).
Powerful, free inspection software – but with a 2019-era learning curve
GOM Inspect 2019 remains a standout release in the metrology world. Even years later, it’s a go‑to tool for many quality engineers, especially because the free version still offers extensive functionality for 3D mesh and CAD comparison.
If you are learning this software today, focus on the Parametric Tree workflow. Understanding how to reorder
You need two types of data: the Nominal (CAD model) and the Actual (3D Scan). Gom Inspect 2019
If you are looking for a robust, non-subscription-based 3D inspection tool with a proven track record, Gom Inspect 2019 is an excellent choice. New users should note that while the software is no longer being updated (end-of-life announced around 2021), it remains fully functional on modern Windows 10/11 systems.
For those performing basic to intermediate quality inspections, the free version may suffice. However, for production environments requiring project saving and team collaboration, the professional license is justified.
To download Gom Inspect 2019, visit the official Zeiss/GOM archives (note: you may need to register as a guest). Be sure to verify if your specific scanner hardware supports the 2019 driver set.
Final verdict: A classic workhorse of metrology software—powerful enough for the lab, simple enough for the workshop. This creates the "heat map" showing where the

GOM Inspect 2019 is a specialized 3D metrology and inspection software used for the detailed evaluation of three-dimensional data. Developed by GOM (now a part of ZEISS), this version introduced several advanced features designed to optimize industrial production and quality control processes. It is widely used in industries such as automotive, aerospace, and medical research for tasks ranging from first article inspection to complex deformation analysis. Core Capabilities and Workflow
GOM Inspect 2019 acts as a virtual coordinate measuring machine (CMM) that transforms 3D scan data into actionable inspection results. The typical workflow includes:
Data Import: Users can import mesh data (STL, PLY) from any 3D scanner, including laser, white light, and CT scanners. Click OK
Alignment: The software offers powerful alignment types, such as automatic pre-alignment (best-fit), which snaps the scanned data to an imported CAD model representing the "ideal" geometry.
Surface Comparison: It generates color-coded deviation plots, where green indicates a perfect match, red shows excess material, and blue signifies a lack of material compared to the CAD reference.
GD&T Analysis: The software supports Geometric Dimensioning and Tolerancing (GD&T) according to ISO and ASME standards, checking for flatness, circularity, and position.
Reporting: Results are compiled into customizable PDF reports that include interactive 3D views and deviation labels for critical points. New Features in the 2019 Version
The 2019 release introduced several "world-first" technologies to address specific manufacturing challenges:
