CATIA VBA: how to get a section view by using projection plane

Hi,dear all;

Here is my question:

I want to create section view in 2D drawing not by using "DefineSectionView";

In other words, when i create a front view, how can i create a section view by operating 

the front view based on itself, just like by using the projection plane to cut the front view;

if there are better ways to solve the requirement, please give a help;

Thanks a lot;
