Thanks for your reply.

I must have been confused between "Grid" and "Object Snap".

Now I can align my line with my model. (overlap)

Thanks again for your answer. It was ice water to my thirst!

Hello,

I tried to put a line on a model that I want to present, but it seems that the grid is not sensitive enough that the line doesn't match the model. I tried with the GRID box, but can't manage it. Anybody have any idea?

Thank you in advance.
