More the constraint icons in the sketch palette you’ll see that the sketch constraints use geometric expressions, with the exception of fix/unfix. If you look at Re-arranges screen to look at selected object. What are Sketch Constraints?Ĭonstraints allow you to relate one sketch entity to another sketch entity.

In this article, I’ll explain what constraints are and then I’ll explain what each constraint actually does. In order to master Fusion 360, it’s important that you have a solid understanding of sketch constraints.
