Steps in a model-based lifecycle
Create• MBD CAD model with 3D annotations and metadata
Release• With required quality standard
Translate• Derivatives for delivery or downstream consumption
Validate• Ensure derivatives equal released creation
Inspect• Quality at the digital level

Data Translation Support• Entities
– Geometry– Product Structure – PMI/FTA– Attributes – Features – Sketches– Constraints – Associative 2D
Drawings
• CAD platforms– CATIA V4 / V5 / V6– NX– Creo Parametric– SolidWorks– Inventor
• Neutral/Viewable– STEP– JT– Parasolid– ACIS– STL– OBJ– 3D PDF– HTML– IGES
• Translation of geometry, annotations and attributes
PMI Translation
Support both native PMI/FTA translation and appearance translation.
Full Annotated 3D Drawing Translation
Keep associativity between annotation and element.
Enable to map specific annotation and attribute to others to recover non-supported entities at destination CAD.
Flexible Mapping of PMI/FTA and Attribute
Map spot weld point of CATIA V5 to user attribute of specific parts of Inventor which are automatically created as spot point symbol through translation.
• Feature-based 3D data translation maintains design intent and enables modification by features.
Feature-based Translation
Automatically extract feature tree from source CAD, map the feature tree to destination CAD, and re-build 3D model at destination CAD with the mapped feature tree.
Full Automatic Translation
2. Recover un-supported features as B-Rep translation.
1. Translate representation of fabricated material as geometry and definition of machining feature as feature tree.
Hybrid Translation of Feature and Geometry
B-Rep.
Feature
Support sketch and assembly constraints.
Support feature mapping capability to recover un-supported features of destination CAD.
Validation of MBD Data• Quickly identify differences between 2 files
Reports available via XML, DiffViewer, HTML, and 3DPDF
• Validate:–Translated derivative–Engineering changes–CAD Version upgrades
• Customize reports:–Pass/fail criteria–Downstream usability–Multiple use cases
