- In this FreeCAD tutorial, we explain what are degrees of freedom and how to correctly constrain them.
Motivation: For complete beginners, one of the most confusing parts of learning FreeCAD is what are degrees of freedom in a 2D sketch. Furthermore, complete beginners often struggle with properly constraining all the degrees of freedom.

WARNING: If you do not properly constrain all the degrees of freedom, then your 2D dimensions might change during some operations! Always completely constrain the 2D sketch!
