ANALYSIS OF IMPLEMENTATION OF MBD AND STEP AP242 STANDARD INTO MODERN CAD TOOLS

摘要

THIS PAPER PRESENTS AN OVERVIEW OF RECORDING DATA ON TOLERANCES AND PRODUCT SURFACES, USING THE MODEL BASED DEFINITION (MBD) METHOD, AND THE TRANSFER BETWEEN VARIOUS MODERN CAD MODELERS, USING THE STEP AP242 STANDARD. WITH MBD IMPLEMENTED IN DESIGN PROCESS, WE PLACE 3D MODEL IN THE CENTER OF DEVELOPMENT. REFERRING TO THAT, THERE IS NO NEED FOR SEPARATE 2D DRAWING FILES AND THAT MAKES SIMPLER MANAGEMENT WITH ALL PROJECT DOCUMENTATION. USING MBD INSTEAD OF 2D DRAWINGS CAN BE TIME SAVING, WHEN WE ARE DESIGNING COMPLEX MODELS WITH A LOT OF PRODUCT MANUFACTURING INFORMATION (PMI). BY PRODUCING THE SAME MODEL IN DIFFERENT MODELERS, ADDING PMI TO MODELS AND CONVERTING MODELS INTO STEP AP242, WE REVIEWED THE RELEVANCE OF CONVERSIONS AND MODELERS. THE RESULTS HAVE SHOWN THAT MODERN MODELERS OF THE LATEST GENERATIONS ARE COMPATIBLE WITH THE ISO 10303-242: 2014 (STEP AP242) STANDARD AND ALLOW RELIABLE TRANSFER OF PMI BETWEEN DIFFERENT MODELERS USING THE MBD METHOD.
