This article considers the building conception of zero block for CAD/CAM/CAE/PDM systems. Zero block is considered as a complex of calculating and optimizing modules, integrated into the CAD structure. The feature of this block is working in a space of sketch coordinates. On a stage of the project realisation the models from zero block are used as a base of the digital model of the end product.
Keywords: CAD/CAM/CAE/PDMsystems, zero block, design, innovation and investment decision, project management..
