Hello everyone, I am new in here, and i am sorry if i am not posting this thread correctly.
I am desperate, i am learning to use CATIA V5(i have a student license) and my problem is that many times i get open profiles on sketches, even if i am sure 100% i gave coincidence to the points ( i often control this by giving distance between lines and it always results zero), tangency to radii etc.
I really beg you to help me, otherwise i will never be able to give a pad or a pocket to my sketch!!!

Truly thank you.
