Thank you for this colletion, will bew useful when I get my algorithm stablefreecad-heini-1 wrote: ↑Wed Nov 01, 2017 11:08 am Further information concerning topological naming:
Re: topological identification of vertexes on a part
@microelly2 it seems the forum ate a (rather lenghty) reply from me. In short: I will test you code when I have time.
I hope to rewrite my post eventually.

Re: topological identification of vertexes on a part
I just read this article:
http://www.sciencedirect.com/science/ar ... 00117#bib1
What i like about it is it gives a nice and clear overview. And it doesn't just focus on the proposed solution.

Re: topological identification of vertexes on a part
I find it good to research different possibilities to solve this, however as I understand this is probably still the primary implementation of it that we have for now:

Re: topological identification of vertexes on a part
Looking at this table. It would be nice if our proposed solution could be placed in it. That is where do we stand with PID. Will it be Topology or Geometry based or hybrid. Is it heavily based on one of the existing methods (highly likely)? If yes/no what are the key points, advantages and disadvantages of the selected method we will use? I wouldn't mind if such answers could be provided at some point in the future. To remove the ambiguity involved to some extent (not only from the topology point of view).

Re: topological identification of vertexes on a part
wow, a lot to read for tomorrow
I have improved my methods today a little bit
here the result
I want to look for a good topological match. When I have 5 good points pairs identified
than I can calculate from one part to the other using the coordinate system.
but I think topology is the most important thing:
Look at the crash test of a car: the only thing which will be invariant is the topology of some subparts.
the scripts and model is all in my nurbs wb.
