In this paper is detailed a CAPP activity modeling taking into account the acquisition of technological documentation. It is achieved in the AutoCAD system by generating a number of SCRIPT files, which perform calculation and provide the necessary information to fulfill the operation plan sheet. The operation plan is also recorded on the disk, in the AutoCAD library, in a block format with attributes. The block attributes are the information required from the Computer Aided Design of Technology System (CAD), for the completion of the operation plan. The operation drawings are recorded also in block format with attributes. All these blocks are AutoCAD files with the extension *.dwg.
