summary |
In the field of industrial manufacturing and building design procedure, B-Rep (Boundary Representation) model is often used to design and fabricate building components or molds, but in the finite element analysis(FEA) procedure, engineers often need to use the F-Rep (Functional Representation) model files. So, converting two file formats back and forth from one to another is a very important topic in architectural design and manufacturing process. However, there are still some limitations to carry out the conversation process efficiently on discontinuous B-rep geometries with existing software and plug-ins. In this paper, authors introduce an efficient retopology method with kangaroo physics plug-in based on Rhino platform to convert a B-Rep file into a F-Rep file (a continuous uniform mesh infinitely approached to the original geometry with a controllable face numbers) within limited steps. Thus, designers and engineers can do creative parametric design or finite element analysis continuously without surface boundary limitation. Furthermore, the mesh converted by the method introduced in the paper has a better regularity on each single face and better homogeneity of all faces than the built-in "QuadRemesh" function in Rhino-7. |
