Open Cascade presents the newest version of CAD Builder – a generic tool for parametric modeling. The solution allows creating 3D models, modifying them, and reusing them in other applications. With CAD Builder users can change initial objects, entered parameters, insert intermediate operations and get the final model modified accordingly.
CAD Builder 1.3.0. is transferred to the Open CASCADE Technology version 7.5.3 with additional patches. New features and improvements were implemented in order to make the solution more performant and stable in terms of algorithms.
