In application point of view, is a bridge between CAD and CAPP, furthermore, it is also a good connecter of geometry topology information of CAD and special engineering information to improve the utility of CAD, CAPP and CAM and to make new sense for parts CAD module, from combination of geometry topology information to special engineering information.

特征不仅仅是连接CAD与CAPP、CAM等领域的一个桥梁，更重要的是它可将CAD中的几何拓扑信息与具体的工程信息紧密地连接起来，提高了CAD、CAPP、CAM等的实际应用成熟度，使得产品模型由原始无工程意义的几何拓扑信息组合变为具有工程意义的特征信息组合。

Preoperatively and postoperatively computed tomographic scanning was performed in every patient. For the CAD treatment group, firstly, the 3D graph of the patient's skull was built based on the CT data using the reconstructing function of Mimics 8.11. Then the 3D file was imported to Geomagic 4.0. The injury lateral was resected and replaced by the mirror of the intact side, so an intact skull was generated at last. Consequently, a model was manufactured in a technical machine. The last step was to prebend the titanium mesh on the model.

CAD/CAM治疗组是利用术前诊断CT，将DICOM格式CT数据输入图像处理软件Mimics8.11，由软件生成颅颌面骨STL格式的三维图像文件，应用另一个图像处理软件Geomagic4.0读取该文件，并应用镜像工具以中线为轴线生成健侧半的镜像，最终得到双侧对称的颅颌面模型，将该图像信息输入快速成型系统，通过逐层树脂堆积，生成树脂头模。
