Abstract
Standards-based Engineering Framework for Next Generation Product Lifecycle
Management
Manas Bajaj and Russell Peak (InterCAX and Georgia Tech), Lothar Klein (LKSoft and InterCAX), Mike Dickerson (InterCAX),
Dirk Zwemer (InterCAX)
We envision a computer-based engineering framework that encapsulates tools, models and methods associated with products
and processes in the engineering world. A framework with this scope abounds with diversity of representation, techniques,
interfaces and agents (humans and computers). Open standards (ISO STEP, W3C XML, OMG UML, etc.) enable to bridge this
diversity with richer knowledge representation and semantic continuity.
In this presentation, we focus on current and emerging standards-based technologies that shall play a central role in realizing
this engineering framework for next generation PLM. We shall discuss and demonstrate the role of IDA-STEP in providing a
framework for standards-based model and technique integration.
IDA-STEP (www.ida-step.net) is a standards-based PLM application that enables the integration of CAD, CAE, PDM and
Manufacturing Process models in a multi-user, distributed environment. In its current generation, IDA-STEP uses STEP-based
content models for product and process descriptions in the following domains: electronics (AP210), automotive (AP214),
mechanical (AP203), cabling (AP212), systems engineering (AP233). Additionally, IDA-STEP uses XML-based technologies for
highly customizable and rich user interface.
IDA-STEP supports models generated in many common ECAD, MCAD, Systems Engineering (SE), PDM, Manufacturing
Process Planning (MPP) applications via STEP-based translators and interfaces available for them. In some cases, IDA-STEP
has direct extensions available for these applications.
The list of applications currently supported by IDA-STEP is as follows:
MCAD - UGS-NX, CATIA, ProE, IDEAS
Cabling – EPLAN, Logical Cable (prototype)
ECAD - Mentor Boardstation, Zuken Visula, EAGLE, OrCAD
PDM - UGS Teamcenter Engineering
SE - UGS Teamcenter Requirements, DOORS, MS Project
MPP– eMPlanner
We shall also highlight some key CAE-based applications that use the standards-based product models created / enriched by
IDA-STEP for high fidelity analyses.

Conflicting Constraints on
Product Realization Systems
Engineers need to…
 Realize complex virtual products
– …with rich knowledge representation
– …across multiple disciplines
– …in a distributed environment

Use intuitive and simple application interfaces
– …to conceptualize products,
– …to evaluate models (simulation-based design), and
– …to connect different levels of abstraction and stages
of development

Rich Features in AP210: Electrical Component
The 3D shape is generated from these “smart features” which
have electrical functional knowledge. Thus, the AP210-based
model is much richer than a typical 3D MCAD package model.
210 can also support the detailed design of a package itself
(its insides, including electrical functions and physical
behaviors).
