lines and polylines

[451]

Hello, everyone.
I am learning to use inventor (ver 2025) and apologize if probably my question will be banal.
in the 2d sketch mode, if I select the command "line" the software creates a series of single lines, while until a few days ago created me a polylinea (sick). Now, if I move a segment, this is detached from the other segments, while before it was attacked.
I must have changed some parameters, but I can't find it.
Thank you for your help.

application options --> sketch --> constraint setting --> deduction settings --> popping up constraints and keeping constraints --> ok --> application

Thank you so much! Now it works as I wanted.
I will try to be more careful with the settings changes.
