Showing intersect path correctly in 3D Graphics

I created an applet which helps students learn the shape of the cross section by a plane and cylinder several days ago. However, I find a problem that doesn't match reality. Here is the capture image showing the problem225dc5a9a71718c82e2cf966dbbda9f2


The orange region is the cross section showing by geogebra. I know that if the plane can be extend infinitely, indeed the orange region fits the result showing by geogebra. But I just want to show the region with ticks without region marked red pen, how can I do that? (The reason why I want to do this is that the plane is restricted in blue square).

Oh, that is fine. But it marks the inferior arc. How can I show the major arc?

Je ne comprends pas, c'est "OK" pour moi (la couleur n'est pas trop belle)
