Feature Name: Smart Anomaly Cause-Assign (SACA)

2. The Basic Workflow

The standard workflow in GOM Inspect follows a logical order:

Import Data $\rightarrow$ Align (Register) $\rightarrow$ Pre-inspection $\rightarrow$ Create Dimensions $\rightarrow$ Reporting

Why Gom Inspect 2019 Still Matters Today

Despite newer versions existing, Gom Inspect 2019 holds a special place in the metrology community. It represents the last major release before the Zeiss integration, offering a mature, stable, and (in its free form) accessible platform for entry-level and professional metrology. Gom Inspect 2019

Educational institutions rely on it to teach GD&T without expensive licensing. Small machine shops use it to inspect parts on a budget, using an off-the-shelf 3D scanner. And engineers in the field appreciate its reliable batch-processing capabilities.

1. CAD Import & Nominal/Actual Comparison

The software excels at aligning an actual scan (mesh) to a nominal CAD model. The "Local Best Fit" and "RPS (Reference Point System)" alignment algorithms in 2019 are remarkably robust. Users can generate a 3D color map instantly, showing deviations between -1mm to +1mm (customizable) across the entire surface. Feature Name: Smart Anomaly Cause-Assign (SACA) 2

3. Parametric Inspection Concepts

GOM Inspect is built on a parametric kernel (similar to CAD software like SolidWorks or NX), unlike some competitors that use a history-based "tree" that is rigid.

• The "Live" Update: If you realize you scanned the part in the wrong orientation, you don't need to re-do your inspection steps. You can simply re-align the part in the software, and because the parametric structure links the alignment to the GDT checks, every subsequent measurement updates automatically.
• Revision Management: This is vital for tracking changes. You can swap the underlying CAD model (e.g., from Revision A to Revision B), and the software will attempt to map all your existing inspection points to the new geometry.

Step 1: Import Data

You need two types of data: the Nominal (CAD model) and the Actual (3D Scan). Why Gom Inspect 2019 Still Matters Today Despite

1. Go to File > Import or click the Import icon in the Toolbox.
2. Import CAD (Nominal): Select your CAD file (STEP, IGES, CATIA, etc.). This is your reference geometry.
3. Import Scan (Actual): Select your scan data (STL, PLY, OBJ, or native scanner formats).
4. Tip: If you import the CAD first, GOM will automatically treat it as "Nominal" and treat subsequent scan data as "Actual."

Gom Inspect 2019

GOM Inspect 2019 is a version of GOM’s inspection and metrology software suite designed for processing, analyzing, and reporting on 3D measurement data from industrial scanners, coordinate measuring machines (CMMs), and computed tomography (CT) systems. Built around a CAD-neutral workflow and strong visualization tools, GOM Inspect targets quality engineers, metrologists, and product developers who need to validate manufactured parts against CAD models or nominal data, to perform reverse engineering, or to evaluate deformation and assembly behavior.

The Problem It Solves:

Currently, users can detect deviations (e.g., a red spot on a surface comparison or a failing tolerance on a bore). However, correlating that deviation to a specific manufacturing cause (e.g., tool wear, fixture issue, temperature drift) is manual, time-consuming, and often relies on tribal knowledge.
