Modeling Precision Parts in
Litigation

Thorough, Detailed Documentation

IIA has extensive experience scanning and modeling components at the center of litigation. When you need scanning and rendering for court presentation or to make a record of actual geometry prior to destructive testing, IIA’s equipment and methods have been developed to obtain the most accurate results for each size of part. We can accommodate your chain-of-custody requirements in each of our labs. Your project will be personalized - managed by a highly skilled individual with whom you will have a direct line of communication.

Engineering Services

Built for responsiveness.

IIA strives to provide services worth telling others about. We've structured our entire operation to be responsive to your needs – from precision equipment to be used on your type of parts, to IT systems built for optimum communications and data integrity; we strive in every way to provide story-worthy service.

To take you to the next step.

When you begin a project with us, we'll want to know your stated and unstated project needs. We value making and keeping aggressive commitments to help you get to the next step in your project. You’ll know the accuracy of the CAD model or scan we provide by attending a live on-line review at project close. With a vast set of resources in multiple locations, there is always a way to get your scanning or modeling job done.

Scanning Outputs

Point Cloud

Raw 3D Scan Data (.txt, .asc)


Generated by all 3D scanning technologies, raw geometric data is collected as a point cloud. This is the first step in every project.

Polygons

Raw 3D Scan Data with a polygonal wrap (.stl)


Neutral file primarily used by the 3D printing industry.

Analysis

2D Visual Report (.pdf)

3D Interactive Report (.pwzip)


Point cloud data is overlaid to an existing CAD model or scan data of another part to show deviation. Used for rapid design verification, tooling validation, and first article inspection.


Referred to as a Deviation Analysis, Comparative Analysis, Computer Aided Inspection (CAI) or Verification (CAV), or Color Map. Reports can also be manipulated to show specific dimensional call outs or FAIs. We call this a "CAV Plus".

Modeling Outputs

Native Parametric Formats

Models developed in your native CAD platform. Constructed with a fully functional design tree, robust models are built for ease of editing.


NURBS File Format

Best for modeling organic shapes that do not need to be edited. Surface or solid file output (.igs, .stp)


All Reverse Engineering and Modeling project customers receive a Live Model Review at project completion.

Scanning vs CMM Inspection

When you may need dimensional inspection vs 3D scanning.

Does your inspection involve a large number of dimensions?

Measuring multiple features can be done with both a traditional CMM and by extracting the data from a 3D scan. However, it is generally more efficient to extract a few dimensions from a 3D scan than several hundred. As a guide, 20 (or fewer) dimensions on 1 or 2 parts is a good number for 3D scanning. As the dimensions and number of pieces increase, programming and inspecting with a CMM is more cost effective.

Helping you find the best solution.

IIA is dedicated to helping you solve your quality and design challenges. In these situations, we work with IIA Inspection to create solutions that are comprehensive, cost-effective, and appropriate to achieve your goals.
