Improving Validation for 2D & 3D CAD Data

Abstract

CAD data is constantly being changed, translated, and shared. It's

important to track these changes, validate that only what is meant

to be changed gets changed, and that every derivative matches

the original data. Many companies validate data manually. It's

difficult, however, to catch every change and it takes time. This

process is cumbersome and inconsistent, not to mention unreliable

and in fact risky. Many companies, however, recognized these

issues and found a better way to stay ahead of the process. Come

join Elysium as we discuss how companies have implemented an

automatic, customizable, high fidelity validation process for 2D and

3D CAD data that has saved time and given confidence in their

data.

Typical Change Process Today

18ENGINEERINGCHANGENOTICE – COSTIMPROVEMENTS

Hanging Paper: the process of

defining and approving a change,

but not incorporating it into the

documentation. Instead, defining

the product definition as “This

Drawing/Model plus this

unincorporated but approved

change.”

https://www.cmpic.com/PDFs/CM

Trends_Issue11_2012_12a.pdf

https://www.cmpic.com/PDFs/CMTrends_Issue11_2012_12a.pdf



Reasons for Change

Design Mistake(Form, Fit, Function)

• Requirements incorrect or changed

• Material Specification incorrect or unavailable

• Design error not caught until testing

TTP Mistake

• MBOM Definition

• Material not available

• Work Instruction error

• Tool design error

Safety

• End user safety issue

• Manufacturing production process issue


Including, but not limited to



Risk of Manual Process Today

Creating

• Relies on complete manual documentation

• Description

• Language

Consuming

• Relies on complete realization

• Interpretation

• Ambiguous

• Time-consuming



Automate Detection & Reporting:

Geometry, PMI, & Attributes



High-Value Bonus: Unintended Change Detection

• Users can self-check their work

• No more

• No less

• Improve disciplined modeling practices

• Verify change did not impact unexpected areas

Sloppy design work

caused the 3D

annotations to move

ENGINEERINGCHANGE TERMS

Engineering Change Process

Starts when ECR is created

“Scoper” is assigned to determine justification and the scope of the request

ECN “Scoper”(title may vary)

A person who identifies all things affected by an ECR

Plans all aspects of the request change and presents to ECB

After approval, initiates and supports TTP to incorporate the ECN


ENGINEERINGCHANGE TERMS

Change Incorporation

The process of scoping and planning and executing an ECN

Change Review Board

Management positions that authorize a change to be incorporated

Usually comprised of Design Engineering, Manufacturing Engineering, Operations Planning, QC, CM and Procurement leads.

May include Logistics, Tech data, others as required and determined by the ECN “Scoper”
