Dimensional analysis involves the comparison of a manufactured part or component to the specifications defined by engineering drawings, digital files and 3D CAD models, or a master tool or part. Historically, the scale of measurement capability has ranged from very large (airplane wings and automobile contours) to the micro level (printed circuit boards and micro electronics).

Dimensional inspection includes many types of scanning devices for a broad range of applications. In the realm of 3D Scanning, the level of detail that can be captured makes it the method of choice, especially for measuring very small objects requiring non-contact measurement methods.

One of the most common types of non-contact 3D scanning is structured light scanning. Used for both dimensional inspection and reverse engineering, structured light scanning employs projected light and cameras to measure the three-dimensional surfaces of an object.

Although accurate and precise measurements are key components of dimensional inspection services, these are not the only qualities you should look for in a provider. You want a partner that can help you solve problems and identify potential issues that you may have not yet recognized.
