大家好，今天要介绍的是关于平面、曲面相关的API。
下面是相关的API:
（1）第一个为ISurfacePlanarFeatureData，这个API的含义为允许访问平面表面特征，下面是官方的具体解释：
下面是官方使用的例子：
This example shows how to create a planar surface feature.
//----------------------------------------------------------------------------
// Preconditions:
// 1. Verify that the specified document template exists.
// 2. Open an Immediate window.
//
// Postconditions:
// 1. Creates a new model document with a boss extrusion.
// 2. Creates Surface-Radiate1 and Surface-Plane1 in the FeatureManager
// design tree.
// 3. Inspect the Immediate window.
