With this release IDA-STEP is making another big step towards ASME Y14.41 & ISO 16792 on "Technical product documentation - Digital product definition data practices". First converters for major mechanical CAD-systems are becoming available to generate the Geometric dimensioning and tolerancing (GD&T) data. IDA-STEP is supporting all available STEP data on both, the presentation (annotation, callouts) and feature level together with Cross-Highlighting in Viewer Pro 3D. For viewing and editing of big STEP files a 64 bit Windows installation is now available in addition to the 64 bit Linux installation.
