Inspection of geometric details and GD&T annotations
3D Model with GD&T annotations

With the release of version 4.3 IDA-STEP is entering the area of Geometric dimensioning and tolerancing (GD&T) on the basis of ASME Y14.41 & ISO 16792 "Technical product documentation - Digital product definition data practices". Several vendors of mechanical CAD are currently testing GD&T data exchange within the CAX-IF using STEP, ISO 10303. Release of first converters is expected soon. This activity is supported by the LOTAR project (LOng Term ARchiving) driven by the European and US aerospace industry. With IDA-STEP you can visualize and inspect all this information and in addition define your own styling models.
