We will work with the default sector.
First off, staying in top view, cleave the sector in half, from the top of the screen to the bottom.
Then, switch to the side view by pressing [shift+2]. Now, select the right hand sector, and cleave it diagonally from the bottom left hand corner, up 2 grid dots on the right side. Please refer to the picture if you have questions.
Now, change your grid "snap" to 0.4. This will allow you to make stairs small enough that the player can actually walk up. It is also a good idea to change your grid dots to be at 0.1. On to the cleaving!
With the triangle sector selected, cleave the top off as shown below. You will cleave as close as possible to the top corner, without actually being ON the top corner.
Now, switch to vertex mode, and select the bottom left vertex of the newly formed small triangle. The correct vertex is shown below.
Now, with that vertex selected, press [shift+s] to align the grid to it. Then, select the sector underneath the triangle as shown below.
Now, cleave the sector straight down from the vertex that had been selected. Refer to the picture below.
With the sector above selected, delete it.
Now, cleave the bottom sector again to create another step.
Move back to vertex mode, select the bottom left hand corner vertex, and again snap the grid to it by pressing [shift+s].
Once again, cleave the sector strait down from that vertex, and delete it.
You should be noticing a pattern here. You select the sector, cleave the step, snap to the lower left hand vertex, align the grid, cleave strait down, then delete the remaining sector. If you do this till you reach the bottom of your staircase, you should have something that looks like this:
Now, if you texture it up, you have a nice looking stairway going up one side of your original box.
Remember to make sure you have all the surfaces that make the steps flagged to be floor, as described in the Basic Editing Techniques page.
