DipTrace PCB Layout module includes real-time 3D preview & export feature. It shows the model of manufactured printed circuit board with all components installed. You can rotate the board in three axes, zoom in and out in real time, change colors of the board, copper areas, solder mask, silkscreen, and background. 3D preview works on all stages of the design. Board can be exported to STEP or VRML 2.0 formats for mechanical CAD modelling. More than 6500 3D models of PCB packages are supplied for free. Externally designed 3D models in *.wrl, *.step, *.iges, and *.3ds formats can be uploaded and attached to patterns in Pattern Editor or PCB Layout.
