After creating a new document with the correct dimentions, i can start with creating the outline of the cabinet
First create circles with the right diameter..

Then color them to see better what i am doing 

Okay, looks like it is one nice path after some seriouse stitching, cropping, splitting and merging 

exchange the fill with transparent, and make the stroke black..

i copied the outline and flipped it so now i got the left and right side as a template

It looks like i need to bend and shape the ck picture a bit more... 
anyway, not today 
if anybody has a better shot of the sideart, i am very interested !
Etienne, in the future we can team-up on projects like that.
You would save tons of time if you give me the dimensions of the sidepanel and I make an outline in SWX (CAD-Programm) that is 100 percent accurate and perfect in all parameters
perfect straight lines
perfect angles (what ever degree)
perfect parallelity
perfect curves and roundings
and so on.
I just checked it and found out that I can save in many formats like .jpg, .tif and so on (I can give you a list if desired) and I can set the print dimenions in mm.....
Also the dpi can be adjustet.
So, if you give me exact measurements I can make a perfect outline.
There are not many roundings in my sketches I postet along with this text as I extrude the outline to a volume-body and use another tool to break the corners but I also can make the roundings in the sketch.
This would be a much much cleaner way and would´nt cost much time for me.
We also could save the file as it can be feed in every cnc-machine that works out a perfect side-panel for people with waterdamages and of course I can render a sidepanel with or with out the artwork on it.
