Hi, I'm new to metasequoia and modeling in general and it's been kinda tough with a lack of tutorials out there.

Is there a way to lock a point to a line? Like in this picture, I wanted to cut half the model and mirror it so I tried to create lines in the middle where it wouldn't cut directly in the middle but the point doesn't lock onto the line that I want it to go on. I'm a newbie so there's some tips and tricks I have no clue about...

EDIT: Nvm, I just redid the top part, making square faces then did a continuous cut
