【Daily project update】3D data for checking clearance of assembly

3D data is a good feature for checking dimension of PC-Board in term of mechanical.
After make position of PCB such as assembly part to board. Some parts need area for those bodies.
Many parts are OK to plate on board if dimensions of parts are correctly.
