C# Solidworks二次开发：程序工具界面和选项相关API详解

大家好，今天要讲的是关于程序工具相关的API介绍。

下面是要介绍的API:

(1)第一个为GetAutoPartSimplification，这个API的含义为获取简化配置的指针，下面是官方具体解释：

其输入参数的类型在上一篇文章中已经介绍过了gtError_e，返回值为指向简化配置的指针。

（2）第二个为GetOptions，这个API的含义为获取solidworks实用程序选项，下面是官方的具体解释：

其输入参数的类型如上所示，返回值为指向选项数组的指针。

（3）第三个为GetToolinterface，这个API的含义为获取solidworks中实用工具的指针，下面是官方的具体解释：

其输入值有两个，第一个为输入定义工具的ID，如下所示：

第二个输入参数为报错，如上面所示。

返回值为指向SOLIDWORKS实用工具界面的指针。

下面是官方使用的例子：

This example shows how to use the SOLIDWORKS Utilities API to compare geometries in two part documents.

'---------------------------------------------------------------------------------
' Preconditions:
' 1. Add the SOLIDWORKS Utilities as an add-in
'    (in SOLIDWORKS, click Tools > Add-Ins > SOLIDWORKS Utilities).
' 2. Add the SOLIDWORKS Utilities interop assembly as a reference
'    (right-click the project in Project Explorer, click Add Reference > 
'     browse to install_dir\api\redist > Solidworks.Interop.gtswutilities.dll).
' 3. Verify that the specified files exist.
' 4. Verify that C:\test\ exists.
' 5. Open the Immediate window.
'
' Postconditions:
' 1. Creates C:\test\Report\gtReportIndex.htm.
' 2. Gets the face and volume comparison statuses.
' 3. Examine the Immediate window, graphics area, and 
'    C:\test\report\gtReportIndex.htm.
'
' NOTE: Because the parts are used elsewhere, do not save changes.
