STEP AP242 "Managed Model Based 3D Engineering"

With the new version 4.5 IDA-STEP is now supporting the new STEP Application Protocol AP242 Managed Model Based 3D Engineering. AP242 is an upward compatible merger of AP203 and AP214. Once AP242 is finally approved the intention is to withdraw its ancestors AP203 and AP214. Currently AP242 is in the Committee Draft (CD) stage. Testing of data exchange between various CAD-Systems has already started within the CAX-IF.

A major feature of AP242 are support of the new enhanced capabilities in the area of Geometric Dimensioning and Tolerancing (GD&T) as defined in ASME Y14.5-2009, ISO 5459:2011 and ISO 1101:2011 (to be published). IDA-STEP version 4.5 takes advantage of these new capabilities.
