  1. The STEP ISO Standard Dr. David Loffredo VP Product Development STEP Tools, Inc. 216 River Street / Troy, New York 12180 Voice: (518) 687-2848 / Fax: (518) 276-4420 info@steptools.com http://www.steptools.com

  2. What is the Problem? • Product Process Management (PPM) is most expensive but least automated function of large engineering companies • Must include the supply chain • Poor communication, often just drawings or FAX’s • Incompatibilities among computer systems, applications, and data formats used to create and store engineering information • Difficult exchange and sharing • Leads to data re-entry • Leads to decreased quality / increased turnaround time • Barrier to Internet / e-Manufacturing

  3. STEP Data Exchange There are now more than one million STEP enabled CAD stations in the world With CAM and CAE systems following

  4. What is STEP • An International Standard for technical data about products including • Geometry and topology • Assembly and configuration information • Manufacturing attributes • Move to STEP initiated by CAD users in US, Far East and Europe in 1984 • More interoperability in design and manufacturing • Independence from CAD vendors • Reduce costs for supply chain • Two hundred of the worlds best product data specialists meeting three times per year to progress the standard for the past fifteen years.

  5. Who we are • Software tools to make implementing and using the STEP ISO standard easy. • Forerunners in STEP technology since 1991 • Founders working on product data since 1978 • First commercial software tool kit • First solid model data exchange using STEP • First STEP Repository • Contributors to STEP and STEP-NC meetings • Owner of Parts 14, 21, and 24 of STEP • Owner of Parts 3 and 51 of STEP-NC • 300+ customers use our tools to define and implement STEP and STEP-NC

  6. Some Customers Enterprises Aerospatial Boeing British Aerospace EDF ESA Ford General Dynamics General Electric General Motors Hitachi Zosen IBM Lockheed Martin NASA Newport News Peugot Raytheon Samsung Toyota • CAD Vendors • SGI Alias, Bentley, Unigraphics, CADKEY, Cimatron, HZS, Entity Systems (Alibre), Intergraph • CAE Vendors • Tecnomatix, Deneb • PDM Vendors • IMAN, Boeing DCAC/MRM (Metaphase) • CAM Vendors • Bridgeport Controls, DelCAM, Licom, Fanuc Robotics

  7. Product 1 1 N N Product Definition Formation (version) Product Definition STEP Product Information Product Categories (inheritance hierarchies) P41 Each Product Definition describes a particular view of the product (mechanical, thermal, electrical, etc.) P41 Administrivia (who did what) P41 Application Protocols give the context! P42, 43 P44 Property Definition(s) (including shape) Product Structure (including assembly)

  8. AP-203: Configuration Controlled 3D Designs of Mechanical Parts and Assemblies • Configuration Management • Authorization • Control(Version/Revision) • Effectivity • Release Status • Security Classification • Supplier • Geometric Shapes • Advanced BREP Solids • Faceted BREP Solids • Manifold Surfaces with Topology • Wireframe with Topology • Surfaces and Wireframe without • Topology • Specifications • Surface Finish • Material • Design • Process • CAD Filename • Product Structure • Assemblies • Bill of Materials • Part • Substitute Part • Alternate Part

  9. AP-227: Plant Spatial Configuration • Plant Layout • Location of plant-items • Site Description • Change Control • Plant Item • Type • Connections • Functional/Physical • Definition/Occurrence • Plant Systems • Line Definitions • Composition • Capabilities • Component Connectivity • Functional/Analysis • Interference • Performance Requirements • Requirement Satisfaction • Shape • Explicit Shape • Brep • CSG

  10. Part • Functionality • Termination • Shape 2D, 3D • Single Level Decomposition • Material Product • Characteristics Product Structure/ Connectivity Physical • Functional • Packaged • Component Placement • Bare Board Geometry • Layout items • Layers non-planar, • conductive & non-conductive • Material product Configuration Mgmt • Identification • Authority • Effectivity • Control • RequirementTraceability • Analytical Model • Document References Geometry • Geometrically Bounded • 2-D Shape • Wireframe with Topology • Advanced BREP Solids • Constructive Solid Geometry Requirements Technology • Design • Allocation • Constraints • Interface • Fabrication Design Rules • Product Design Rules AP-210: Electronic Assembly, Interconnectand Packaging Design

  11. Application Protocols Information requirements usually described in EXPRESS. Also an activity model that sets the scope. Model is different for each AP ARM Mapping that encodes the ARM in the AIM. Described as tables or using EXPRESS-X. MAP Model is same for each AP Information implementation always described in EXPRESS. Common library of definitions. AIM Need to know to understand Part 22 Part 21 Data exchange file Database Used by systems at run time

  12. Other Parts of STEP • Definition Infrastructure • Part 11: EXPRESS Language describes information models. • Part 14: EXPRESS-X Language describes views and queries. • Common Library of Definitions • Part 40’s: Common definitions for product structure, geometry, topology, dates, approvals, presentation, etc. • APs reference these definitions and give additional context. • Implementation Infrastructure • Part 21: Exchange file format for communicating data sets defined by an EXPRESS schema. • Parts 22-29: APIs for working with EXPRESS-defined data in languages like C, C++, Java, XML.

  13. Road Map Machine Resources ISO 14649, AP-210 AP-212, AP-225 In Pipeline Numerical Control Electrical Assemblies AEC Assemblies AP-214, PDM Schema AP-227, AP-224, AP-209 In Process Features & Tolerances Life Cycle Control Drawing and Presentation Mechanical Assemblies AP-203 Here Solid Model Geometry 2000 1998 2010 Here: Available in most CAD/CAM systems In Process: Available in some CAD/CAM systems being tested in others In Pipeline: Specification being finalized by ISO

  14. Mechanical Design - AP-203/214/224 NIIIP, SMART, STEP-NC, MDICM, AM3 (Funding = $7.3m) Proved out geometry models, translators, AP-203 in every MCAD system. Process Plant / Shipbuilding - AP-227 SHIIP, SPARS, ISEC, WSME (Funding = $2m) Proving out product configuration models, large scale databases, viewers, AP-227 translators in progress for most process plant systems. Electrical - AP-210/212 PreAmp, more are needed. (Funding = $50k) Must prove out multi-discipline model, link between design requirement and physical model. No commercial implementations. Project Histories

  15. Conclusion • STEP is a success in MCAD and process plant. • Strong support from industry projects brought results. • Vendors followed with commercial translators. • The ECAD systems cannot ignore geometry. • The MCAD systems cannot ignore connectivity. • This program can prove out the AP-210 model and create viewers and databases to bring success in electrical domain.
