Es legacy System & Data Migration

  1. 1. LEGACY MIGRATION WITH AUTOMATION USING ACC-U-TRANS AND LDA TOOLS“Engineering is the conceptualization, design, construction, andadministration of projects and products. Whatever the field or application, anengineer solves problems with imagination, creativity and synthesis of varioussources of knowledge”. W H I T E P A P E R S
  2. 2. O view verLegacy System & Data MigrationA legacy system is an old method, technology, computer system, or application program thatcontinues to be used, typically because it still functions for the users needs, even thoughnewer technology or more efficient methods of performing a task are now available. A legacysystem may include procedures or terminology which are no longer relevant in the currentcontext, and may hinder or confuse understanding of the methods or technologies used.Data migration is a process of translating 3D models & 2D drawings from one CAD system toanother CAD system which lets users create, view and modify assemblies built withcomponents created in different CAD systems. Many manufacturers, both large and small, usemultiple 2D and 3D CAD systems & upgrading to the newer technology; Data migration ismost indispensable to use the archive or legacy data for their new product development.

  3. 3. Legacy Data Conversion Manual Process! Identify the data to be converted from one CAD platform to other CAD platform.! Process considered for the conversion of data from IDEAS (Source) to Pro/E (Target).! Understand the limitation & standards for the data to be converted.! Create IGES / STEP for 3Dmodel & IGES / PDF / DWG format for drawing from source software.! IGES / PDF / DWG drawings will be input for creating parametric 3D model in Target software for models with definite dimension using manual method.! Else IGES / STEP will be used to create parametric model for the models with surfaces.! Create 2D drawings from the generated 3D model as per the Input drawings from Source software.! Verify the 3D data from source to target software with different method like import IGES / STEP in the target software & compare the models for deviation.! Other method would be to overlay 2D drawings from source & target software.! Perform the Quality check for both 3D model & 2D drawing.! Any deviation in the Quality check, rework to achieve the specified requirement.! Package the model & drawing & upload to the customer data base.PRO/ENGINEERPro/ENGINEER is a parametric, integrated 3D CAD/CAM/CAE solution created byParametric Technology Corporation (PTC). PTC was the first to market parametric, feature-based, associative solid modeling software.There are three basic Pro/ENGINEER design steps from conception to completion:! Part creation! Assembly creation! Drawing creationWe can use Pro/ENGINEER to create a complete 3D digital model of the products. Themodels consist of 2D and 3D solid model data which can also be used downstream in finiteelement analysis, rapid prototyping, tooling design, and CNC manufacturing. All data isassociative and interchangeable between the CAD, CAE and CAM modules withoutconversion.2D drawing using Pro/E 3D Model using Pro/E Legacy System & Data Migration 3
  4. 4. Acc-u-Trans - Feature Based Part TranslationAcc-u-Trans literally build the model feature by feature right in the target CAD system. If thetarget CAD system needs assistance with any feature (either because the feature type doesnot exist in the target system or the target system cannot resolve the geometry being deliveredto it) Acc-u-Trans goes through its patent pending “Interrupt” process. Once the issue isresolved the system continues the creation process.Acc-u-Trans is the only feature based CAD translation tool that allows an operator through atranslation interrupt process to resolve these differences during the translation. This ensuresthat the feature tree is always complete and updates without error in the new CAD system.This unique combination of software and operators produces results similar to manualremastering of CAD models in a fraction of the time it would take to complete manually. Thisprocess mirrors the actual design process CAD designers use every day (resolve or massagefeatures into the design that the CAD system struggles to resolve by itself). Further, it cantranslate models that might not even lend themselves to manual remaster in another CADsystem.When to Use Feature Based TranslationsThere are many reasons companies consider a feature based translation strategy. A partial listwould include:• Legacy data from another CAD system whether through acquisition or system change• Contract designs completed in another CAD system• Companies that utilize a multi CAD system strategy for leveling design work• Obtaining new customers that require CAD data deliveries in their CAD system of choiceThe key point to consider when analyzing translation methods is the required use of themodel after translation. If you need the feature intelligence in the model then your choices arelimited. A neutral or dumb translation will never provide this level of modifiability. There maynot be time or the use of the model does not warrant the expense of a manual remaster.Where the need and frequency of model modification is high then a feature based translationstrategy can be a very high value alternative.SolidWorks 3D Model Acc-u-Trans Translated Model to Pro/Engineer Legacy System & Data Migration 4
  5. 5. Overview of Acc-u-Trans• Three Step, Feature Based, Process Centric Translation Software• Completely Feature Based Part Translation Between All Six Major CAD Systems• Claims 70% increases in productivity when compared to manually re-mastering models.• Easy To Use Batch Processing• Extensive Status and Summary Reports in Each Translation Step• Automatic Assembly Creation• Batch Processes Optimized For Assembly Structure• Geometric Analysis of Translated Models with Mirror Model Comparator SoftwareLDA - Legacy Drawing AssociatorThere is technology Invented by PTC that exists today to address the migration of CAD data.This technology, called the Legacy Migration Extension (LMX), provides a suite of tools toassist in migration data from one CAD system to another.A big part of LMX is a tool for re-association of imported 3D models to otherwise un-associated 2D drawings. This tool, known as the Legacy Drawing Associator, maps 3D modelgeometry to a separately imported 2D drawing. It then re-maps dimensions and notes to the3D solid geometry on that same drawing so that model modifications are reflected withdrawing dimension updates. The result is a 2D drawing that is, once again, fully associative to a3D model.Advantages of LDA v/s Conventional / Manual method• LDA is fully automated otherwise reduction in time over Manual method.• LDA has shorter cycle time over Manual method.• LDA can be used for any CAD system (Input is neutral format IGES / DXF).

Case study: Improving product efficiency using Pro/ENGINEERAbout Client:• Easy to implement the customer standards since LDA map views, dimensions & notes to input IGES drawings.• LDA is an simple tool & easy to understand by any CAD engineer (Semi skilled engineers)• LDA process has very minimal Human errors compared to Manual process.• LDA systematic approach eliminates loss of drawing entities.• Easy to manage massive Mechanical/ electrical / electronic drawings• LDA handle most languages like Chinese, Japanese etc.Factory Model Concept - LDA Input Stage 1 Stage 2 Stage 3 Stage 4 Stage 5 Quality Sorting Import Map model Relate Map Clean Up Check IGES / DXF & Map to View Annotation View LDA Correction Associates relating non- Associates Moving Quality Supports of import views to the associative dimensions redundant/ check IGES / DXR errors model entities to notes & duplicated through PV as input file the view Symbols entities to overlay format the layerOur Client is a Leading Medical Diagnostic Equipment Manufacturer with sites across theglobe, Headquartered in the United Kingdom with a $17 billion Company. Worldwide,employs more than 46,000 people committed to serving healthcare professionals and theirpatients in more than 100 countries.Business need:Globalization, Changing demographics and Technology are changing consumer base rapidlyincreasing. This creates huge demand but not necessary for the same product at the sameprice tags. These forcing companies think differently and re look at their cost and createproduct that meet needs of market and trends. Legacy System & Data Migration 5
