'I remember librecad had both constraints and dimensions functions in the old version.'
Are you  sure you are talking about LibreCAD? I have never read about constraints with LibreCAD. There is Tools - Modify - Properties where you can edit some values, depending on the kind of entity, but probably not to the extent you expect.

You can stretch the endpoint of a line to a different position by clicking on the line, thus highlighting it, grab it at one of the small square handles and pull it elsewhere. If you want to put it on a circle, have 'Snap on Entity' activated.
Alternatively you can use Tools - Modify - Stretch.
