Creating a bevel car decal like effect? I am trying to create a 3D bevelled version of my own logo 


And make it look something like this:

or this 


Where it is beveled in the middle.
Currently I have tried taking in a svg file into blender, tried their curve bevel options. It just bevelled in depth not in width 

I even tried to convert my curve into mesh and then extruded/scaled in the middle but due to the curve – mesh conversion the faces wouldn’t scale uniformly and it was all over the place. I was wondering if there was another way to create something like this?

Thanks

Edit: 
This what happens when I use the curve bevel

And this is what happens when I have converted to mesh and tried to scale it in.
 
Perhaps it is my design or the way the curve is converted but the points seem to go crazy.
If you set your curve to full, add some depth and leave the resolution at 0 it seems that it will just create the look you are going for. You need to set the shading to flat so you can see the sharp edge.



There is also a star curve that you can tweak with the curve settings to get the desired look of a Mercedes star. Not sure it will yield the perfect results for any shape, but you could try.
