Modern product definition is commonly achieved by geometric dimensioning and tolerancing through a 3D CAD model. This is particularly important where complex, non-prismatic, free-form or organic geometry exists, as conventional dimensioning is not feasible.

IIA is fully conversant with Model Based Definition. Unusual shaped geometry requires unusual verification techniques. We have a wide array of special equipment, software and techniques to properly analyze 2D and 3D contours. Our methods both qualify and quantify the results.

IIA provides innumerable application-specific solutions ranging from abbreviated vector-driven key features inspections to extremely comprehensive part-to-CAD comparisons using high-density scan data. Such analyses can be best-fit using a number of algorithms to achieve “by-the-book” results for complex profile requirements.
