SUMMARY
Most researches on lattice structures focus on the boundary representation (B-rep) models, which require to be transformed into a triangular or quadrangular mesh before simulation. In this paper, a volume parametric modeling method of three-dimensional (3D) lattice structures is proposed based on the skeleton. In the entire modeling process, the construction of the volume parametric nodes is the key step. A volume parametric modeling method of complex nodes is achieved. Different types of volume parametric unit-cells and lattice structures are created. Researchers have proposed numerous modeling methods to construct lattice structures . . .
