大家好，今天要介绍的是关于几何公差IGot相关操作的API。
几何公差之前没有讲过，具体API如下面所示：
（1）第一个为GetText，这个API的含义为获取此几何公差的指定文本部分，下面是官方的具体解释：
其输入参数有一个为swGTolTextParts_e，在API定义有四种，分别为：
| swGTolTextCalloutAbove | 3 |
| swGTolTextCalloutBelow | 4 |
| swGTolTextPrefix | 1 |
| swGTolTextSuffix | 2 |
返回值为文本内容。
（2）第二个为GetTextCount，这个API的含义为获取此几何公差的文本项数，下面是官方的具体解释：
其没有输入参数，只有输出参数，参数为文本对象数量。
下面是官方使用的例子：
This example shows how to get text items, values, and symbols in a GTol frame.
//-------------------------------------------------------------
// Preconditions:
// 1. Open document with a GTol frame and select that GTol
// frame.
// 2. Open the Immediate window.
//
// Postconditions:
// 1. Gets the text items, values, and symbols in the
// selected GTol frame.
// 2. Examine the Immediate window.

swModel = (ModelDoc2)swApp.ActiveDoc;

swSelMgr = (SelectionMgr)swModel.SelectionManager;
swGtol = (Gtol)swSelMgr.GetSelectedObject6(1, -1);
Debug.Print("GetTextCount = " + swGtol.GetTextCount().ToString());
for (int idx = 0; idx < swGtol.GetTextCount(); idx++)
{
Debug.Print("GetTextAtIndex(" + idx.ToString() + ") = " + swGtol.GetTextAtIndex(idx));
}
int count = 0;
count = swGtol.GetFrameCount();
count = count - 1;
Debug.Print("GetFrameCount = " + count.ToString());
for (int idx = 1; idx <= (swGtol.GetFrameCount() - 1); idx++)
{
Object myParams;
Object mySymbols;
myParams = swGtol.GetFrameValues((short)idx);
if (myParams != null)
{
Array myParamArray = (Array)myParams;
Debug.Print("GetFrameValues(" + idx.ToString() + ") = " + myParamArray.GetValue(0) + "," + myParamArray.GetValue(1) + "," + myParamArray.GetValue(2) + "," + myParamArray.GetValue(3) + "," + myParamArray.GetValue(4));
mySymbols = swGtol.GetFrameSymbols3((short)idx);
Array mySymbolsArray = (Array)mySymbols;
Debug.Print(" GetFrameSymbols3(" + idx.ToString() + ") = " + mySymbolsArray.GetValue(0) + "," + mySymbolsArray.GetValue(1) + "," + mySymbolsArray.GetValue(2) + "," + mySymbolsArray.GetValue(3) + "," + mySymbolsArray.GetValue(4) + "," + mySymbolsArray.GetValue(5));
}
}
}

/// The SldWorks swApp variable is pre-assigned for you.

public SldWorks swApp;
}
}
（3）第三个为GetTextFont，这个API的含义为获取此几何公差的字体，下面是官方的具体解释：
其没有输入参数，返回参数值为几何公差字体的名称。
（4）第四个为GetTextPoint，这个API的含义为获取几何公差的文本参考点，该点是边界矩形左上角，下方是官方的具体解释：
上面就是本篇文章的全部内容，我们下篇文章再见。
