What is the best way to draw this shape

Hi.

My level is beginner.
I have CorelDraw X5 installed and I have to draw this shape:

Here is the specification:

I used the Freehand tool but I can't understand how to assign distance between nodes or position of nodes.
So what is the best way to draw this shape ?

Regards.
