C# Solidworks二次开发：访问平面、曲面相关API详解

一个会的不多的人2024-04-28 23:39

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.
