So yes, I was playing a bit around yesterday with that to see if I could quickly come up with some more interesting results but I guess things cannot always go as fast as one would like to
So as per the above links, Dynamo has this "Zero Touch Plugin Development" where you are able to import custom nodes. It will actually load any
.NET .dll file and expose its classes as nodes, so I searched for .NET OpenCascade and found this http://www.sofa.de/OCasDotNet/Index.html
(yes it is old) and have simply load it in to Dynamo (warning it takes quite some time to load). The nodes are there and can be used but I don't know and did not really had the time to find out how to make it work in an useful way...
So yes, anyone that is interested to play with it can just download Dynamo and this .NET Wrapper for OpenCascade, open Dynamo, start new, go to File > Import Library... and load OpenCascade6.2.dll.
It was anyway just a quick test and is probably not really the right way to go for it, but I guess some of the developers (those that already have knowledge of OpenCascade) might have a better understanding of what can actually be do with it. However it would probably make more sense to write some custom wrapper, maybe also the better way would be a wrapper for FreeCAD or FreeCAD command line? I don't know, but I do believe it would be possible to do it, probably even not very hard for someone that knows to code in C#.
The problem with this is of course that it would be Windows only, since as far as I understand Dynamo is Windows only... Well, Microsoft has open sourced .NET recently, so I don't know... ?
