The overview develops at full speed in computer technology today, treatment of evaluation of the design that three-dimensional geometrical modelling technology already was used extensively at product and industry pattern by manufacturing industry, program, automation is made reach management to safeguard each respects. The technical data that we receive from upriver manufacturer may be the three-dimensional model of all sorts of data types, but, as a result of all sorts of reasons, the possibility that we face is not the model of CAD, however real objective kind, sometimes, the blueprint that can consult even a piece possibly even is nonexistent also, this is us to use advanced design method and advanced production in follow-up work the technology brought very big obstacle, we must pass all sorts of measurement method and three-dimensional geometry establish modular method, will original objective (product prototype or greasy filth model) the three-dimensional number model on translate into computer, in CAID and CAD domain, this is so called converse project (Reverse Engineering) . A few should note problems in converse job do the work of a converse project, the likelihood challenges a gender than doing to be being had more to the design, if want,make an ideal product because of you, must understand the design ideology of original model as far as possible above all, want repair possibly still on this foundation or overcome the limitation that exists on original model. Look from some kind of meaning, converse also be a redesigned process. Before beginning to have a converse project, we should consider carefully a few more the following point: The type of the model: Free curved surface, of car, autocycle outside enclothe, other stamping workpiece, the module that when the type of the spare parts model of the composition such as the plane of ─ of ─ of elementary and analytic curved surface such as the toy, columnar face, taper seat matters to us to build a model directly, chooses or software, to free curved surface the module that must collect appliance in the right way to adjust curve and curved surface, and to elementary and analytic curved surface, we are done not have necessary the curved surface that because have,measure data and draft syncretic Zhang Xianran with free curved surface is plane or columnar face. The character that the model asks: Class A curved surface, be like car, autocycle outside cover a B class curved surface, the interior trim that is like a car, major plastic the character that the curved surface model with an other lower demand asks also matters to pair of module choose, for instance to class A curved surface, choose software to must be had with respect to the requirement go to the lavatory to adjust a method with direct curved surface, powerful curved surface detects function, and detecting must be trends as a result, while curved surface is adjusted, detect namely result trends is newer. Of course, there is 100 percent thing on the project, it is with the class A curved surface of the surface outside the car exemple, to 2 faces piece the connection error between, main bedding face: Tangent error should is 0, and curvature error allows to be in 0.

1 less than; Tangent to other curved surface error allows to be in 10 minutes less than. Measure a method: The handiwork of simple tool measures machine 3 coordinate are measured machine laser of metrical orderly dot data, number measures data into the 3 coordinate that resemble, already if the large quantities of quantities, data nodding the cloud that does not have foreword needs to compare accurate expression primitive objective, use laser, number to become more convenient like measurement technique, if need to measure main molded lines only, measure with machinery opportunity is equaler. The character of original objective, measure the precision of data, whether to have noise place, when be being measured for many times fiducial how to consider, the error has how old. If the quality of original objective is higher, measure data precision taller also, the curved surface that builds and measure data to should adjust less numerical value, for example model of good to comparing car greasy filth, the error after adjusting should small with 1.

5 - 2 millimeter. What build the downstream application domain of the model, it is for the design merely, still be for mould, treatment or analysis. Do a design only for instance, can take no account of details of a few technology, wait like rake of drawing of patterns. But if want to undertake machine and be analyticed, criterion model must complete. If have mould design and treatment, certain roundlet horn can omit, by cutting tool when treatment automatic belt goes out. The converse tool that PTC company can provide is current, in the product of PTC company, can use at processing measurement point data, undertake the module of design of converse curved surface have: ICEM Surf, Pro/DESIGNER (CDRS) , Pro/SCANTOOLS, each provide a characteristic, apply to different applied domain. ICEM Surf is the tectonic tool of curved surface of freedom of a class A, its the mainest characteristic is direct and tectonic curved surface (need not construct first curve) evaluate with the trends of curved surface quality (curved surface adjusts medium curved surface to diagnose result trends to update) , enclothe outside car, autocycle, interior trim waiting for free curved surface to construct with it is do a job with skill and ease. But had better have more complete measurement data, of course the design that ICEM Surf also can use at tectonic curved surface. ICEM Surf still can change the data that nod the cloud automatically triangularly a model, can try aleatoric and sectional line, attrib border line and diagnostic line with it, also can be done with it shape quickly or NC machines process designing. But this face is not the curved surface model on a traditional sense. Pro/DESIGNER (CDRS) is the modelling module that an industry designs, basically use at notional design, its characteristic is OK special and convenient adjustment each molded lines, get stylist wants gotten result thereby. With Yu Ni to when, can use in measure data less, the circumstance of only and main molded lines and boundary boundary line, this is a part actually is converse, handlers is converse basically is the modelling thought of the product. Pro/SCANTOOLS is one is finished complete works builds the compose of converse curved surface in the model to propose a package at Pro/ENGINEER substance, the function in 2000i new edition has very big rise. Can accept orderly point (slotted line) , also can accept the data that nod the cloud, can use compose to build the free curved surface that is not class A, if general industrial product is electric equipment product, general plastic, car interior trim wait to all can apply this module to get satisfactory settlement. To the part that makes by elementary and analytical side, the substance that can use Pro/ENGINEER directly and plan of curved surface unifinication are solved. OK of course and direct measure data to regard formative as the basis, but what should emphasize is us the fine structure with the functional particular and rather than that the purpose of converse product is a product. Had begun in new century today, information and technology develop at full speed, what we choose is a good tool not just, more important is a complete solution, still should choose good support, good service, choose a partner that has good progress perspective.
