Best way of creating 2D mesh from curve? just wanted to know if there is a quicker way of creating a 2D mesh from a bezier curve?

Right now i just end up with some kind triangular shape that i have to delete the bottom vertices from, and then set the Z axis on the remaining vertices to 0.

Using the 2D option instead of the 3D doesn't have any effect for my purpose. 

Here is a demo of my current method:

You can switch Fill  option to Front so you don't have the lower part
 :


or you create another Curve and flat it on the Y axis and use it as a bevel  object :
