Up to now, plenty of CAD softwares have no function of extension for non-circular curves. Intelligent extension-technology for non-circular curves was studied in this article based on a principle of trend extrapolation. Four kinds of intelligent extension-models were built. These models include quadratic extension-model, cubic extension-model, exponential extension-model, and Gompertz extension-model. Moreover, some methods identifying and choosing for extension-models were discussed, respectively. Several applications of intelligent extension for non-circular curves were offered, which shows us that some curves can be extended for a long distance accurately while they are consistent with the type of extension-models; on the other hand, extension-models built can be available for approximate extension for a short distance while the shapes of non-circular curves are arbitrary. The theories in this paper, as core technologies and key generic problems, can be used for existing CAD softwares to upgrade or develop secondarily.
