How to Create an L‐Shaped Stairway on AutoCAD

Creating the Stairs

1. 
   Make sure your snap cursor to 2D points tool is active with endpoints checked. This will allow you to place objects properly touching each other. You will notice endpoints when selecting and moving objects. They will be small green squares located at corners of the object that snap to other endpoints when dragged.
2. 
   Create a rectangle using the rectangle tool under the drawing section. This is located under the home tab.
3. 
   Select, then copy the existing rectangle with Ctrl+C and paste with Ctrl+V. This will ensure that our stairs are all uniform in size.
4. 
   Place this rectangle directly next to the original. The lines should endpoint snap, creating a seamless connection between the two stairs.
5. 
   Repeat this process in order to place desired number of stairs.
6. 
   Select, copy, and paste a new rectangle directly above or below existing rectangles. Re-select the rectangle with the rotate tool. Rotate this rectangle's bottom pivot point 90 degrees and select ↵ Enter to confirm its placement.
7. 
   Create a landing by using the rectangle tool and creating a square in the space between the rotated rectangle and the original flight of stairs. Make sure all corners are snapped to the rectangles' endpoints.
8. 
   Copy the previously rotated rectangle and paste another in the direction you wish to have your second set of stairs follow. Do this for however many steps you would like.
