Hi 
I am a beginner to a grasshopper.
I am trying to make a chamfer (parametric) on top like in the picture shown through gh.
Could someone help me create this one? I tried to use fillet edge and left the script uncompleted
Thanks in advance!

P.S. Oh wait, I just noticed that your horizontal and vertical offsets are not the sameâŚ
Yes, there is a RhinoCommon method Iâm sure someone will be glad to implement.

I may suggest using Edges From Points to retrieve the edges index (using the edge middle as a reference).
As a workaround for the 2-dimensional chamfer, here are two methods, one building sweeps and subtracting the solids, the other one building the box with the chamfer with Loft.

Youâll have to fix the units yourself, looks like you mixed up inches for the box and millimeters for the chamfer offsets (blue group).
Thank you much @Joseph_Oster and @magicteddy for all these solutions 
I am going through those solutions and will let you know if i did not understand anything in there. 
@magicteddy wondering why shift paths was done to get the data from back? why not simply connecting offset curve to merge component does not work? 
could you explain me in a very basic way?
This is a problem with the Merge component and the fact that single items ot lists still have a branch number associated with them, that cannot be simplified.
Due to internal reasons, the Offset Curve component adds a tree level so the curve ends up in the {0;0} branch, whereas the other ones are in the {0} branch. If you merge them directly, you end up with a tree with two branches, and not a list of three elements, which is what we want for the Loft to work.
Other options are : flatten all inputs of the Merge component (quite barbarian in my opinion)
Use Suirify component
Use my Smart Merge component (from this thread Multiple node connecting - #6 by magicteddy) - but be careful that if you send the definition to someone that doesnât have the plugin installed, it wonât work.
You could flatten the âCurvesâ input to Loft, as I did.
If curve sequence is important, you can use Entwine instead of Merge first, then flatten its output instead of the âCurvesâ input to Loft.
Wow excellent
With these solutions I could know many other components and how it works. Itâs exactly what i was looking for.
The reply you marked as âSolutionâ, important as it may be, doesnât address the topic of this thread.
Actually, it solved my problem which is why I marked as solution.
I am kind of new here âŚSo are you saying Its not recommended to do that?
Yes, I am saying itâs not recommended to do that.
Flattening a data tree is a separate issue from âFillet Edgeâ, which is what this thread is about.
