Help! Using clipping plane and make 2D!

Im trying to make a 2D drawing of the model using a clipping plane… however when using the front or any flat view the result are just a few nonsense lines… but when I used a perspective view the result is perfectly fine. I really need to do some section cuts with the front view. Here is my file, can anyone help me?

no file here.

check if the clipping plane is active in those planar views from the properties panel

Indeed, I ran into this inattention mistake a few times.
Bringing an alert (or an info into the tool panel) saying that the make2D result display could be itself hidden by the clipping plane(s) could be usefull for some of us.

…but still no file from our friend.
