Standards Review: AP242 and JT

11

• First choice has been done – to be in the ISO context

• Second choice - work in Model BasedDefinition (3D) context

• Assess the geometric definition

• And also the GD&T and PMI

Conclusions

28

• GOOD results on geometric definition on AP242 and JT

…some troubles on assembly but it sounds it is a question of mistake in using translators than wrong definition in the

standards

• More DIFFICULTIES in translating PMI on JT then AP242 …

…clarifying semantic representations and graphical presentations

Future Work

29

• More use cases, more criteria, more translators or direct translator in CAD systems!

• Method without toolkit for browsing and processing of JT binary files

• Question still open on exact geometric definition vs tessellated definitionvs large model rendering, and on associativity between PMI withgeometry (exact or tessellated)

The role of MBD and 3D Models as unquestionnalable backbone Digital Transformation of company?
