PresentationPresentationDATAKIT : presentation

Editor of technical data exchange software

Company founded in 1994 by Francis Cadin, previously at GOSET

Core business : conversion of native or standard 2D/3D CAD data

Competence and long time experience in CAD interoperability

Long time involvement in forums and works focused on STEP :Participation in Cax-IF from start , participation in PDM-IF

Participation in LOTAR Group , in Step Manufacturing Group

Active participation in work groups dedicated to STEP AP242

Participation in AFNOR CP/IDMI committee

Participation via MICADO in works of SASIG (technical data quality)

Research projects : ANGEL on STEP-NC, SIP on test platforms

PresentationPresentationCrossCADWare : a quick presentation

Solution for Exchange and Interoperability of CAD data

Wide coverage of CAD data, 2D & 3D

Autonomous solution (no dependence on third part components, making easier its installation and use)

Homogeneous access to data defined in various CAD formats

Organization of CrossCADWare software :Common structures for data exchanges

Integration in user applications : Software development kit : (libraries / API : CrossCAD/Ware)

Conversion from file to file (CrossManager)

Plugins (for Rhino, SolidWorks, Think, OpenCascade ..)

Used for : CAD, CAM, Metrology, Simulation, Visualization, Documentation ..

PresentationPresentation

CrossCAD : a quick presentation


STEP in the CrossCADWare exchange solution

Protocols : AP203/AP214/AP242 and interoperating protocols

Format : Part 21, AP242 BOXML, compressed or not

For an application : the API presents data in a way homogeneous with other CAD formats

Read mode : normal (complete computations for ready to use result), fast (computations are deferred to the caller application)

Functional coverage of CAD and PDM : following slides

CrossCADWare & STEP, March 2016 : version V2016.2

Current works and Evolution

AP242 Edition 1 supported from 2014

Current work mostly concern PMI semantics

Works on AP242 BO (Business Objects) in progress, firstly on assemblies, for availability on 2016

Works on AP242 Edition 2 and Part 21 Edition 3 for availablity as soon as published IS (International Standard)

Other developments on : parametric geometries, features (especially machining features), kinematics



Semantic PMI in STEP AP242

(test case from NIST)



(test case from NIST : a dimension)



Composite Tolerances


Semantic PMI

Current works on dimensions

(case of a multiple dimension)


PMI in Assembly : current works


STEP-NC (AP238) and AP242Machining Features – use in CAM

In relation with works on AP242E2, AP238, ..

Association between working steps of the machining process and the geometrical items of the CAD model : « Machining Features »

Machining Features : « final » (attached to the design model) or « in-process » (attached to the machining process)

Works in progress on Additive Manufacturing
