IMPORT & GEOMETRY RECOGNITION • Import of any 3D CAD model from files in STEP, IGES, STL formats • Display of the loaded model and basic visual operations like zoom, rotation, selection of model objects, delete objects, etc. • Recognition of the geometry of 3D shaft models in mechanical design according to the German DIN 743 • Recognition of the shaft elements independent of DIN 743, determination of the general geometric properties • Recognition of other part models in mechanical design while the library is developed further and is enhanced EXPORT OF 3D MODELS • Creation of various 3D models in mechanical design and building units: basic geometric objects, shaft elements, pinions, bearings, bolts, screw-nuts, beams, etc. Full list of units currently supported can be seen in the CAD Xpansion SDK Guide & Reference document • Export of created 3D models to the universal formats STL, STEP, IGES • Creation and export of complex units using operations like transformation, subtraction, unification, intersection, etc.

* Provides operations similar to the drawing operators of PostScript and PDF. Operations in cairo including: * Stroking and filling cubic Bézier splines * Transforming and compositing translucent images * Antialiased text rendering. * All drawing operations can be transformed by any affine transformation (scale, rotation, shear, etc.)
