I'm trying to follow along with Quanon's tutorial on how to begin modeling. I get down to a part where it says something about connecting edges with a feature that I'm guessing is only available in 3DMax, so I have no clue what to do. Would someone please help?

If you name that feature then someone will be able to point you in the right direction.

If you name that feature then someone will be able to point you in the right direction.

It's the small button next to connect under Edit Edges tab in Max.

OK, nvm. Looks like that question has been answered.

But now I have a question about the answer:

Then you'll need to go into select Vert. You'll have to adjust each Vert, which you just created, cause of the Cutting. Fill in the box of the Z-value (most of the times). Use the Move Tool, to drag the Vert to the right height (what you like of course), look at the Z-Value, copy that over to all the other verts. And should get straight new edges.

Which vertices am I supposed to edit, and how exactly?
