B4 Benchmark Model

Round17J Benchmark Model Results
The Assembly got shifted during some exchanges
issues are being investigated
Torque Converter Assembly
63 exchanges
7
Round17J B4 Basic Validation
As should be the case, the shifting is captured
by the Centroid Validation Property
Torque Converter Assembly
17 exchanges
8
Round17J B4 Assembly Validation
The shifting issue is not reflected here because
the respective system does not support Assembly

Round17J B4 Comments Conclusions

• Looking at the raw numbers, results are better
  than in Round16J
• A CATIA V4 model was also tested, but the native
  model showed significant issues, so it was
  dropped from the evaluation
• Resources at PROSTEP are allocated to rework the
  model
• This test case was tested with Extended
  Validation Properties
• Not all vendors supporting this participated in
  this round
• Minor syntax and structure issues have been
  identified
• Will be re-tested in Round18J with Extended
  Validation Properties

K1 Surface Validation Properties
11
Round17J Surface Model Results
This problem wasnt captured by the ValProps
because the vendor causing it does not support
ValProps.
13 exchanges
12
Round17J K1 Comments Conclusions

• Only minor geometric issues
• Exchange of Surface Validation Properties now
  stable
• Since the issues that were the motivation for the
  recent tests have been resolved, this will not be
  tested again in Round18J.

GD3 Geometric Dimensional Tolerances
14
Round17J GD3 General Results

• 3 STEP files submitted (I-DEAS, T-Systems, and
  Theorem UG)
• Results submitted by Theorem and OpenCascade
• I-DEAS and T-Systems do not support GDT import
  due to API restrictions
• Tolerance information could be processed
• Close cooperation of the participating vendors
  with the GDT module team to resolve issues
• Re-test in Round18J with additional functionality

S1 3D Annotation
16
Round17J S1 General Results

• Main motivation for testing 3D Annotation is the
  preparation for GDT presentation
• Participation by I-DEAS and CoCreate, additional
  import by Theorem
• Some structural issues have been identified and
  need to be resolved
• Some existing implementations have not been
  updated since the last tests in 2001
• Some vendors supporting this did not participate
  in this round
• Re-test in Round18J using simple geometrybut
  more annotations with different styles
• Also formally test colors to give Kubotekthe
  chance to verify their implementation

Round17J PM15 CATIA V5
A component with voids in it caused a lot of
trouble because the STEP processors handled it
differently

Round17J PM15 Comments Conclusions

• Nose Landing Gear
• Most problems were caused by the Voids in the
  model
• Some STEP files had a wrong orientation for the
  shell, so the volume was added instead of
  subtracted
• Or it was just represented as a duplicate solid
• Even if it is questionable if a brep_with_voids
  is a real world test case (manufacturability),
  its out there and should be handled correctly
• Transmission Casing
• No big issues
• New Production Models needed!
• From next round on, Production Models will always
  be tested with (Extended) Validation Properties
• Minimal extra effort
• Might render useful information for transfer
  validation

Round18J Schedule
CAx-IF and Review meeting in conjunction with
PROSTEP Workshop STEP Data Exchange
22
Round18J Scope (1)

• Colors 3D Annotation
• Simple Model (Cube) with various annotations
• Validation with target stats plus screenshots
• Also includes formal testing of colors to give
  Kubotek a chance to verify their implementation
• GD T
• Continued testing with extended scope
• Steve Yates / Ed Paff will provide input on new
  test case
• BREP with Voids
• BV1 model (block with two rectangular voids in
  it)
• Old roundtable agreements will be checked
• Has not been tested with a number of current
  systems

23
Proposed Round18J Scope (2)

• Benchmark Assembly
• Continued testing with as much Validation
  Properties as supported by the systems
• Improved CATIA V4 model
• COPS GVP
• Test according to updatedRecommended Practices
• Use simple model in first testto get syntax
  right
• Production Models
• Models needed!!
• Put in as much ValidationProperties as supported
  bythe systems
