Build sills and headers

- [Instructor] Now that we've successfully extruded…the uninterrupted sections of wall,…it's time to start filling in the sills and headers.…Sills and headers are the portions of the wall…above a door or a window,…that would be a header,…and the sill would be the portion…down below here, below a window.…And we can get this information right off the sketches…which are all aligned.…So for example, over here,…we need to fill in a header.…I'll do so by drawing a rectangle…across the top of the wall,…and then I'll extrude that down…a distance equal to the height here,…specified in the elevation,…so I'll just click on the top of the door.…

I don't have to use numbers in that way.…I can just interactively click on the sketch.…And then this door and all the other doors…would be at the same height,…the headers would be the same.…So I should be able to copy this header…and just re-use it…and place it in the proper locations…around the plan where we need it.…Now, over here, we have a different-sized door,…so I'm going to have to construct a new header for that.…
