See how captured and reconstructed geometry can be compared.
These educational examples show scan imagery, reconstructed CAD, and deviation visualization. Project-specific conclusions require an agreed reference and review scope.
Comparison context
A color map should be readable at a glance.
A useful comparison identifies both geometry sets, the visualization scale, and any areas selected for further review.
Near reference
Edge review
Green Near the reference
Blue Low-side deviation
Warm High-side deviation
Notes Reviewed with job scope
Reading comparison evidence
A deviation image is useful only when its setup is understood.
Color is not a pass/fail verdict by itself. A responsible comparison identifies the measured dataset, reference geometry, alignment method, displayed range, and the regions that matter to the decision.
Name both datasets
State what was captured and what reference CAD, drawing, nominal model, or selected geometry is being used. A scan and a reconstruction can represent different intended conditions.
Set the alignment
Best-fit, datum-based, feature-based, and local alignment can produce different visual results. The alignment should match the agreed question instead of being chosen only because it looks clean.
Read the display band
Colors show differences within a chosen scale. The requested tolerance, critical surfaces, coverage limits, and downstream decision determine whether a displayed area needs further review.
