(continued...) Features are even colour coded by default with Parasolids in beige and grey for ACIS.
These combined modelling capabilities provide extensive support for the import of foreign data extensive, even including CATIA .model files.
The direct face editing tools allow imported data to be edited in just the same way as if it had been created in IronCAD.
In addition to solids, surfaces can be imported and used to trim parts or thicken into solids.
This 'hyper-operability' is another core element of IronCAD's flexibility.
Performance has been addressed in Version 4 with the ability to load boundary representations of parts rather than regenerating the entire model.
For Parasolid models the level of detail in view can automatically reduce from photo-realistic to wireframe to balance realism and interactive performance when zooming or rotating complex models.
Bitmaps can be applied to represent threads and grilles to aid design visualisation without adding to model complexity.
Graphic previews of modelling operations avoid the risk of launching time consuming rebuilds that generate undesired results.
Visual feedback is also used to indicate linked features and constraint dependencies.
