MWF-Bore is a comfortable database-driven bore generator for CATIA V5 which is optimised for use in mold construction and tool design. It is fully integrated in the Part Design workbench with an CATIA-like user interface.MWF-Bore allows users to define complex multi-step holes including all manufacturing information (threads, tolerances, chamfers, grooves). This information is saved in the CATPart and can be transferred to the CAx process chain (e. g. CAM systems).The copy function is an important functionality of MWF-Bore: Standard parts are prepared one time with the necessary holes (cutout geometry). Every time the standard part is used in a design the holes can easily be copied (including all manufacturing information) from the standard part to the design.
