looking for a C++ CAD expert, for the opencascade.org project.
I need a program with source to import and display a drawing 3D in *.step format on the Windows Forms, then user can mark the edges of a 3D object, and finally the list of these edges will be written to the json file. And so for the line it will be its beginning and end (x,y,z) for a circle it will be the radius and center and so on... This project can only be done by a person who is fluent in opencascade.org and shows off his achievements.
