| Legacy Product Modernization |
Legacy Product Modernization - also known as reverse or re-engineering,
is a process that is used to create 3D CAD models directly from
physical parts with little or no additional design documentation.
By Digitizing items that have insufficient design documentation
or require CAD data for modern manufacturing methods, a component
can be quickly and accurately re-engineered. Legacy Product
Modernization begins with physical production parts and 2D drawings
(if available). The production parts are digitized and the data
used to create solid models. 2D drawings are helpful, but not
necessary for interpreting initial design intent that may have
been partially lost as a result of production process variation
or tool degradation.
» Why is it useful? 
Legacy Product Modernization quickly and accurately bridges the gap between poorly or un-documented tooling and fully modifiable 3D CAD models useful for modern manufacturing methods. In many cases it is extremely difficult (if not impossible) to clearly define physical part geometry using traditional measurement techniques.
» Are there any limitations?
The challenges of documenting complex geometry are easily
overcome as long as the surfaces to be digitized are within
"line of sight". In many cases, castings can be made of internal
passages that can be digitized separately and added to the
external geometry. Other means of data collection such as:
Physical sectioning, destructive scanning, photogrametry,
X-Ray, CT-Scan, and MRI are also available.

What Kinds of Materials can be Digitized?
Typical materials that can be digitized include: stone, ceramic,
glass, metal, wood, bone, plastic, rubber, wax, and clay.
» How are business goals affected?
The CAD models are created in the current version of the most popular 3D modeling software packages, and are provided in a fully modifiable format. The data is delivered in a digital format, and prototype copies can be made in different sizes, colors, and surface finishes.
» How are the files delivered?
In a digital age, the most rapid form of enterprise communication
is by way of an electronic file. The files we create can be
accessed and retrieved anywhere an internet connection is available
in a matter of minutes, and can be stored using your preferred
storage medium. The files can also be copied to compact disc
and delivered using traditional shipping methods.
» The Technology Behind the Process:
- Sample parts, drawings and available CAD documentation are provided (if available).
- The object is digitized.
- The data is refined and used as a foundation for creating one of the various 3D file types available.
- Prototype Presentation models
are made for design confirmation.
