DISCUS DFM focuses on characteristic management at an earlier stage in the product lifecycle when a manufacturing engineer is analyzing the detailed design of the part. In fact, by helping to define the applicable specs and annotations to include on the design, DISCUS DFM can actually assist with the definition of the Technical Data Package (TDP).
DISCUS DFM picks up where today’s leading CAD tools leave off by empowering the product team to consider the key considerations for manufacturing the part. An overview of the flow:
You start DISCUS by opening the native 3D CAD model in the model/drawing panel.
DISCUS will automatically review the model and its associated PMI and add the balloons to the model and the rows in the Bill of Characteristics.
You select the appropriate part family and likely list of manufacturing processes to consider for fabricating the part.
At this point, DISCUS DFM enables you to evaluate the part DFM by applying rules associated with the part’s features and characteristics versus the likely manufacturing processes.
The evaluation of the part against the integrated manufacturing knowledgebase results in a list of pertinent DFM constraints, recommended annotations/PMI for the part, and more.
When you're completed the analysis of the model, you can export the DFM data for review with the DFM engineer or the entire Integrated Product Team.
With DISCUS DFM, you consistently and correctly add the vital details to the design, giving you the ability to manufacture the new part right the first time. DISCUS DFM is the tool to improve the quality and productivity of your engineers.

3. Detailed Design Realities
The creation of the detailed design documentation is still a
laborious bottleneck for many companies
Producibility (Design for Manufacturing) is frequently not
addressed as part of the engineering design effort
The proper completion of the detailed design really depends
upon the manufacturing processes considered
Manufacturing process knowledge is often not reused and
actively applied during the detailed design
The move towards a model-centric environment introduces new
challenges & demands on engineering

5. Key “Definers” for DISCUS DFM
1. Rather than another simple checklist, help get detailed design
completed quicker and with less design engineering labor
2. Provide the Product Team with a way to easily discuss the
detailed part characteristics and rapidly clarify design intent
3. Enable the engineering knowledge to be captured by engineers,
and provide transparency into the application of rules
4. Enable the manufacturing engineer to be an instrumental part
of getting the detailed design completed
5. Support the principles of “multi-bird” engineering –- the activity
of using a software tool that creates many useful outputs
