Solidworks二次开发—07—控制草图对象
Solidworks二次开发—07—控制草图对象Get All Elements of Sketch Example (VB)
Solidwork中对草图的控制，下面的例子很详细。特征下的草图在solidwork中其实是特征的子特征，我们可以对特征进行GetFirstSubFeature、及GetNextSubFeature得到。
如果有需要大家可以从中找到对直线、弧线、圆等对象的操作。代码是solidworks的示例文件，里面充斥了debug.print，只是向用户显示程序执行的结果。
This example shows how to get all of the elements of a sketch.
