Round 41J Schedule

Planned Scope

Semantic PMI Representation

  • Testing based on AP242 IS and PMI Rec. Pracs. ≥ V4.0.4
  • Based on subset of updated (2017) NIST MBE PMI Validation Project native CAD Models
  • Graphic Presentation, associated to Representation
  • Semantic PMI Validation Properties
  • Editable PMI text strings

PMI Tessellated Presentation

  • Keep parallel test cases for Graphic Presentation
  • Tessellated Part Geometry
  • Focus on Saved Views, element visibility and cross-highlighting

Alternative Part Shapes

  • Sheet Metal Use Case (folded / unfolded part)
  • Using NIST CTC-03 with PMI on folded shape
  • Include Validation Properties for both shapes
  • Include PMI on both shapes (new)

AP242 BO Model XML Kinematics (New!)

  • Rec. Practices and Schema available
  • Test models in work; will be finished by December
  • CAx-IF will work on "Kinematic Motion" first, and move on to "Kinematic Mechanism" later
  • JT-IF will work in parallel on "Kinematic Mechanism"

STEP AP242 BO Model XML Assembly Structure

  • Looking for more interesting test models than AS1 / Spaceship
  • Using Recommended Practices for AP242 BO Model XML Assembly Structure
  • Target use of AP242 TC and Rec. Practices v2.0 (~December 2017)
  • Include User Defined Attributes and Assembly Validation Properties


  • New Test Model and Recommended Practices available
  • Technical discussions will be handled by LOTAR Composites team
