Understanding constraints

- [Voiceover] Before we begin to learn…about sketch geometry, we need to take a minute…to learn about sketch constraints.…There's two different types of constraints…in Inventor when it comes to sketching.…There's dimensional constraint and geometric constraints.…We're gonna look at the geometric constraints right now.…I've gone ahead and created a Sketch Practice.ipt file…that has a single sketch with some predefined geometry.…This will allow us to explore…sketch constraints more closely.…Let's go ahead and activate the sketch…by double-clicking on it in the browser.…

You can now see that the Sketch tab is active…and we're ready to look at sketch constraints.…A constraint by definition limits or restricts something…and in this case, it's gonna restrict the motion…that can be made by a piece of geometry.…Let me show you what I mean.…If you right-click in the Graphics window,…you have an option to Show All Degrees of Freedom,…and if you right-click a second time, you have the ability…to Show All Constraints or F8 on your keyboard.…
