projection of remarkable points

[serdax23]

Good evening, my name is davide and I am an intern at a technical office where I will take care of design for the next 3 months. I used both solidworks and inventor in the past and, with those programs, I know how to solve the problem. I practically do not understand how to enable the option that allows the projection of remarkable points (e.g. an average point) so as to create a sketch starting from it.
In plain words, I have to create a section plan on the technical table but I can only get it started from the middle point of a segment, not for example just above.
the bosses of the technical office cannot solve the problem, ergo I appeal to you:d

you have to activate the alignment indicator. I still prefer to put the primitives initially "near" to where I need them, and then use the geometric constraints to fix them where they really have to be.

Bye.

Thank you for the answer! Would you tell me in the version of st4 where to find the command?
