OpenNurbs Brep

Dear Dale@dale ,could u tell me if i want to get the control point in the model ,what should i do ? i have tried to read it ,but failed .

i found there has a ON_Surface::CV(),but it maybe not use to Brep compoent ,so i am confused .

If you are using the example_read project, why don’t you put a break point on the ReadFileHelper and trace through the code?
