Scanning and CAD Modeling Tooling

Precision For Tooling Development

A combination of scanning and selected dimensional inspection is most often the best approach to capture precision data for tooling development. IIA employees have extensive experience in tool rooms and with tool design. It helps us understand your particular tooling challenges and what you need to solve. Most scans and inspections are performed on die components or mold inserts, but our equipment is capable of handling an entire mold base if necessary. Your project will be personalized - managed by a highly skilled individual with whom you will have a direct line of communication.

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.


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

Neutral file primarily used by the 3D printing industry.


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.

Do you need specific dimensional results to resolve a tooling problem?

A 3D scan may be an acceptable initial validation step for your tooling. However, if you need more detail, a CMM inspection may be a better solution.

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 Engineering 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.


"Not sure how to say this besides - THANK YOU for the quick turn-around! Our customer wanted a big job completed quicker than we could handle. Your group jumped right in and got it going.

We look really good to our customer and their project is rolling along nicely!"
