Dear @laurent_delrieu , I am bringing this old thread. Is there a good way to offset curves that contains line and arc segments? The issue is that clipper offsets only polylines and arcs are represented as many points. The CNC I am using does not like many points, and I would like to have arcs an…

[image] emanuelthebhering: anything more Well … since all my stuff is strictly internal (CNC routing and the likes) the only thing that I can do is to provide some indicative help in case that you want to try to write a C# that does that (Liu’s paper attached above should be your quide).

You might have a better answer in the official Clipper forum: [image] Clipper Download Clipper for free. Polygon and line clipping and offsetting library (C++, C#, Delphi) The Clipper library performs clipping and offsetting for both lines and polygons. All four boolean clipping operatio…

You already helped me in another post, but it was for a different situation of offsets, many thanks. No problem with C#, I am far for been an expert, but I w…

I will check that too, thanks !!
