Research on Parametric Design based on Feature Modeling and Expression Operation
Parametric design allows that the CAD system not only has the capabilities of interactive plotting, but also has the function of automatic drawing. Combined with expression operation, in the paper, the data structure of facade windows is firstly defined utilizing the basic principles of feature-based modeling, and then the characteristic database is built up which is used as the basis for the realization of dimension driven of a CAD system of doors and windows. Moreover, the details of algorithm are also proposed which has fast computing speed and can satisfy the requirements of the system.
