Mirroring features

- [Narrator] To start Link 4.…I will create a new sketch on the front plane.…And I'm a just sketch out the general shape here…and then add some final dimensions and relations.…So I'll sketch out a shape like this.…Add an arc.…And finish off.…Something like this here.…Once I'm happy with the general shape of this sketch…I'll finish it off with a few dimensions and relations here.…

So the angle of 170 degrees.…And same on the top here.…I'll say the total height here maybe 70 mm.…And radius of 30.…Total length here to this center point of the arc.…Maybe 120.…

Also I want these two angled portions to be equal.…That should give me a fully defined sketch there.…I can extrude this now.…I go to Features and Extrude this out.…I'm going to extrude it 80 mm.…I'm going to, not do a blind extrusion, but do a mid-plane.…This just might come in handy later on…if I have to use a mirror plane and so on.…As we'll see in a minute.…

I'll say OK to this.…There's the general shape of my Link 4.…Now maybe I just want to do a cutout.…I'll go on the top plane.…
