How to create a 3D object with even bevel from an arbitrary 2D shape

[peppertower14]

Hello

I would like to create a 3D object from a 2D curve/vector shape. The 3D object should have a variable height and be beveled evenly across the entire shape, similar to how it looks like in photoshop.

Here is a reference picture what I would like to create in Rhino/Grasshopper:

How can I achieve this effect?
Any help would be greatly appreciated.
