Translations:Sketcher Micro Tutorial - Constraint Practices/6/en

Optimum Scheme
Now, in this last screenshot, there is only 1 dimensional, (distance), constraint, with the remaining constraints being geometrical. This is the best way to constrain this sketch. While with a simple sketch like this, one way or the other is no big deal, on larger and more complex sketches, sticking to the minimum dimensions rule will prove out to be beneficial to you and your endeavors constructing geometry with sketches. The geometrical constraints used in this sketch are horizontal, vertical, equal, and symmetry.
