Check that your alignment is correct and the objects are not miles apart. |
To ensure smooth processing of large STL meshes and point clouds in GOM Inspect 2019, adhere to the following hardware guidelines: Hardware Component Minimum Requirement Recommended Specification Intel Core i5 / AMD Ryzen 5 Intel Core i7/i9 (4+ Cores) Memory (RAM) 32 GB or higher Graphics Card (GPU) OpenGL 4.1 compatible (Intel HD) NVIDIA Quadro or RTX series Storage NVMe M.2 SSD Operating System Windows 7 64-bit Windows 10 64-bit
Load your mesh data (typically STL or PLY) and your CAD file (STEP, IGES). Gom Inspect 2019
Use the Prealignment tool to get the parts close, then follow up with a Best-Fit for precision.

GOM Inspect 2019 (now part of the ZEISS INSPECT family) is a standard for 3D metrology, used to process and evaluate 3D data from various scanning technologies. Core Capabilities
To complete a standard quality control inspection, follow these phase steps: Use Edit > Filter to smooth the point
This is the most critical step for accuracy. It mathematically aligns the scan to the CAD model based on surfaces or specific features (holes, planes).
The user selects a specific out-of-tolerance area on the 3D model (e.g., a localized bump on a turbine blade).
When you open GOM Inspect 2019, the workspace is divided into four main areas:
