C# Solidworks二次开发:获取模型、组件、主体的表面积相关API详解

大家好,今天要介绍模型、组件、主体的表面积相关API。

下面是今天要介绍的API:

(1)第一个为SurfaceArea Property (IMassProperty),这个API的含义为获取此模型的表面积,下面是官方的具体解释:

其没有输入参数值,返回值为表面积。

下面是官方使用的例子:

This example shows how to get and override some mass properties of a part.

// -----------------------------------------------------------------------

// Preconditions:

// 1. Ensure the specified document exists.

// 2. Open the Immediate window.

//

// Postconditions: Inspect the Immediate window.

}

(2)第二个为SurfaceArea Property (IMassProperty2),这个API的含义为获取所选组件或主体的表面积,下面是官方的具体解释:

其没有输入参数值,返回值为表面积。

(3)第三个为SurfaceArea Property (ISustainabilityManufacturing),这个API的含义为获取用于制造当前部件的表面积,下面是官方的具体解释:
