Feature Based Alignment
Inspection Service India
Verify every critical feature against the GD&T requirements that matter most to assembly, machining, PPAP, and quality approval.
The Surface Passed. The Feature Failed.
Basic scanners only see the outer shell. Feature alignment extracts the internal datum geometry to reveal the functional truth.
Hidden Geometric Drift
Extracting the true functional axis reveals a positional error invisible to traditional surface heatmaps.

Why Feature Alignment Exists
Select your verification goal to see the required alignment strategy.
Use Best Fit Alignment
Distributes scanning error evenly across all surfaces. Ideal for visual heatmaps and reverse engineering, but completely ignores functional datums and GD&T requirements.
Use Feature Based Alignment
Strictly locks the coordinate system to extracted datum geometry (Planes, Cylinders). Mandatory for PPAP, first article inspection, and GD&T pass/fail validation.
Interactive Coordinate Construction
Hover to mathematically extract features from the 3D scan data and build the perfect datum coordinate system.

What is Feature Based Alignment Inspection Service India?
Dimensional Inspection is the formal verification of physical components against engineering drawings and CAD models using bridge CMMs, portable articulated arms, optical comparators, and laser trackers.
When to Select This Service
Choose dimensional inspection for First Article Inspection Reports (FAIR), PPAP Level 3 supplier submissions, batch quality audits, and shop-floor fixture alignment adhering to ASME Y14.5 and ISO 1101 standards.
