Along with the development of computer hardware technique, cad technique has obtained fast development.It has experienced from two dimensional model, three-dimensional wireframe model, surface model, solid model, product model, characteristic model until up-to-date living model, and the development trend of cad technique must be the evolution from Static Design to the dynamic design that is shaped to the basis with parameter characteristic.It is thus clear that, based on the development and Design system of AutoCAD application software, progressively can not satisfy the requirement of modernization design at present, modernization design trend just is transformed into the design of Three-Dimensional Dynamic solid model from the two-dimensional static Graphics Design.
In today that cad technique is popularized day by day, traditional two-dimensional CAD software is substituted by three-dimensional CAD software just gradually.In numerous softwares, the Solidworks of Solidworks company, PTC S. A.: Pro/Engineer is one of representative outstanding software.It is highly commended by customers based on the advantages such as database that the single complete shut-down of characteristic joins with Dimension Drive deeply since emerging, during the secondary development on these two basis of software is also constantly developing.Yet; Secondary development tool bag ToolKIT based on Pro/Engineer; Because the price of software itself is higher, the software learning difficulty is big, and characteristics such as the software secondary development code is underground; In the secondary development work of carrying out based on Pro/Engineer, just have certain degree of difficulty, this big limitations the process of this software secondary development.
Summary of the invention
