1 XT B-Rep; Making it Real John Juckes Siemens PL SEPTEMBER 12-14

2 What is XT? Based on research from the Cambridge University Computer lab under Ian Braid The world s leading high precision, production-proven, 3D boundaryrepresentation solid modeling format. Open and published Supported by a level-playing field toolkit Page 2

3 XT b-rep Convergence Parasolid is the worlds leading Solid Modelling Kernel. XT is the Parasolid data format ~45% CAD data worldwide is Parasolid format Over 2 million licenses All Siemens PLM Software applications that create or navigate solid models or precise geometry are Parasolid (XT) enabled. XT provides a complete solids representation for JT files Full solids topology Analytic and nurbs geometry NX Siemens PLM application convergence on XT as the common precise data format Common shared tools Consistent functionality Faster overall lifecycle process performance Teamcenter Visualization Page 3

5 Getting XT data into JT XT data extracted from Parasolid-based authoring systems can be imported directly, without modification. Other formats require translation of the Brep into XT Page 5

6 Interoperability: Parasolid XT Pipeline User Standard Data Investment - Estimated 45% of world s 3D CAD models in XT format Community Over 3 million users of Parasolid-enabled systems Application Standard Vendor Adoption Parasolid is selected by major software vendors in CAD, CAM, CAE, collaboration & data exchange Applications Over 350 commercial Parasolid-based systems and inhouse corporate key systems Open Standard Open - Published format, level playing-field access Interoperable Full 2-way version compatibility and translation-free exchange between Parasolid-based applications CAM Parasolid-based Applications CAD CAE Parasolid XT Pipeline Visualisation / Data Exchange In-house XT Is authored, edited and consumed by over 2.5 million users across the product lifecycle XT Is embodied in up to 45% of the world s 3D product designs XT Is open, published and enables translation-free interoperability between all Parasolid-based applications Page 6

7 XT in JT Another step in the process of XT Convergence. Can live alongside JT Brep, but more usually replaces it.. Can be imported directly. Can be created by translation from other Brep formats. Page 7

8 History of Brep in JT JT Brep Late 1990s Derived from the I-Deas Brep. Simple, lightweight. Not fully robust to perform modeling activities. XT 2002 Heavier. Fully robust. Zero-translation of Brep with Parasolid-based systems. ULP 2006 Adaptive lightweight Brep. As precise as you want. As coarse as you need Page 8

15 XT and JT Validation Storing the XT b-rep allows you to validate the quality of the precise geometry delivered in the JT file JT Inspector uses Parasolid Bodyshop to run a series of checks on the integrity of the model. Errors can be highlighted using Teamcenter Visualization The JT file can be imported into NX and further analysed using the full Checkmate PDQ capability. 1. OEM wants to check content and quality before sending to supplier 3. OEM performs design acceptance check 2. Supplier must confirm JT to OEM standard Interactive error highlighting Page 15

16 XT and Multi-CAD JT Preserves exact mapping of precise entities for CAD systems that import JT Full Topology Analytic Support Part of MultiCAD Entity map from JT Bi-directional Translator for CATIAV5 to NX Gives the imported geometry high functional value. e.g.: NX Synchronous Technology direct edit of imported JT Precise reference geometry used for derived CAD design Creating offset face or Assembly constraints CAE and CAM directly from the JT Page 16

17 Downstream Application XT in JT allows direct use by NX in applications such as machining V5 Database JT NX CAM Translate Page 17

18 XT b-rep and JT Visualisation Tessellation Quality Using Parasolid s stringent modelling paradigms to read the CAD data validates inconsistencies with the original CAD model during the translation process. Validates the CAD data has to be good quality! XT faithfully represents CAD solid topology and geometry Highlights any issues in original CAD data early in process. Corrects issues that it can (i.e. within Parasolid tolerance). A correct solid model result is a more faithful tessellated Visualisation. More accurate sections and analysis from Tessellation. Tessellation highlights poor CATIA geometry Tessellation from good CAD geometry Page 18

19 Archival The high fidelity available with XT in JT, together with recent ISO progress makes it a suitable format for long term archiving V5 Pro/E Translate Verify SE Page 19

20 Supplier Collaboration Being on the XT Pipeline enables a richer exchange of data with collaborators, especially suppliers V5 Translator NX Supplier JT OEM SW Translator (XT direct) Page 20

21 Re-Use With XT in your JT files, they can be loaded into NX as native The rich analytic geometry definitions in XT support NX Synchronous Technology to use the Brep as a starting point for new work from partner V5 from suppliers Translate JT Pro/E carryover Page 21

22 Synchronous Technology delivers Simple, direct pull/push tools for editing and creation Make using NX simple, productive and fun YouTube No time stamps (history), no dependencies Simple and quick geometry creation Fast Performance create and edit models without long replay times Easy geometry manipulation Reliable editing No update failures, no long and tedious fixing of failed features Page 22

23 Summary XT is the most widely adopted precise Solid Modelling format. There are a number of sources and routes for XT data to get into JT It greatly adds to the value of your JT across the product lifecycle. Thank You Page 23
