CATIA二次开发入门教程---15 通过点击屏幕创建点
通过点击屏幕，自动创建点， 这里直接建立了一个简单的对话框，通过pushbutton来添加一个回掉函数，函数里面去执行创建点的类。


void DialogTesTCmdDialog::OnPushButtonCreatePointPushBActivateNotification(CATCommand* cmd, CATNotification* evt, CATCommandClientData data)
{
  // Add your code here
! |5 I3 N8 k- e$ A      CreatePointCmd *createPoint = new CreatePointCmd();
}
: H2 q- [- {0 L3 b( j# a6 l% |) n
新建一个catia 的命令，名称为 CreatePointCmd ，接下来要做的就是在 action one 里面进行点的创建，代码如下：
- v2 U5 h$ e& V% M: U( K' d
CATBoolean CreatePointCmd::ActionOne( void *data )
{
  // TODO: Define the action associated with the transition
  // ------------------------------------------------------
CATMathPoint2D point2D =  _Indication->GetValue();
- N2 a4 T2 d- P8 `, R CATMathPlane plane = _Indication->GetMathPlane();
  @: V/ A; r* J! g CATMathPoint point3D;
plane.EvalPoint(point2D.GetX(),point2D.GetY(),point3D);
