With NEXTRA flex-rigid it is possible to bend or fold flexible zones with caracteristics of PCB foil. The subsequent position of the rigid zone shifts true to life with its 3D coordinates. In mechanical complexe installation situations it is not easy to define the length and bending radius of flexible PCB's in a 2D processing. Therefore the laying is possible in a mechanical 3D context. Afterwards the 3D data get transferred as project process to the PCB layout systems. In Nextra both views can be showed in parallel, allowing to see immediately the modifications in the respective other dimension.
