Hi Elang,
I think this is what you were looking for? I included the 2 scripts I used to make your perspective view a flat 2d workplace. Then Flattened the model to 2 units.
There is a bit of lag on some operations because I have my viewport mesh settings very high and the model is not a simple one.
I was a bit sloppy on rotating the flattened perspective back to a regular 2d view, but you could be more precise if you need.
I can show you a regular Bas Relief emboss in some other software if you need to see that.
