Delta Design now includes C3D Toolkit from C3D Labs.
C3D Toolkit is a set of components for creating CAD, CAE, and CAM systems to generate control programs for CNC machines and other engineering software. Reportedly can design 3D bodies of virtually any shape and complexity. Can be integrated into a single workflow, where all product components are included in a common model. Makes it possible to design flex-rigid PCBs, adjust PCBs to adapt to size of cases, prepare assembly drawings, and analyze 3D models for thermal and electromagnetic characteristics.
