In this tutorial I’m going to show you how to create structure of stair in AutoCAD Architecture.

At the bottom of this tutorial you can find a video screencast showing you how to create the structure of stair.

How to create Structure of Stair

  1. Open the Content Browser (Ctrl+4), within it open the Design Tool Catalog – Metric [Imperial], from the left list choose the Stairs and Railings group, and finally the Stairs category.
    Search the Concrete named stair style.

  2. Take the cursor above the AutoCAD Architecture - Blue Iconicon, until the cursor becomes pipette. Keep the left button pressed and soak it up with the displaying pipette.

  3. When the pipette is soaked itself up, keep the left mouse button pressed and drag the pipette into the AutoCAD drawing area, and then let the mouse button go about pouring there the content of the pipette.
  4. Before specifying the start point of the stair, set the base parameters of being created stair on the Properties palette.
    The Shape option is set to Multi-landing,
    The Turn type option to 1/4 turn,
    Leave the Winder Style option on Balanced,
    The Vertical orientation value is Up,
    The Width is 1000 mm [3’-6”],
    The Height is 3000 mm [10’-0”],
    The Justify option is Right.
    The Riser count, the Riser and the Tread parameters are not important now, they will be set later.

  5. The Stair is not inserted to its place at once, you can just put on a place where it is easier to edit and later it will be moved to its place.
    After setting the parameters, snap the ENDpoint shown in the figure as the start point of the stair flight.
    The program marks the justifying of the stair with blue color (right). But if the crosshair is on this line too, it appears yellow.

  6. Start to drag the stair flight to the right, and type 1300 mm [4’-7”] to the first stair flight length.

  7. Then continue up the stair flight, and because you do not want any more winder, drag the cursor until the whole stair flight displays, then Left-Click.

  8. The Stair has been inserted. Press ENTER to mark that no more stairs will be inserted.

  9. For setting of the Riser count and the Riser values, first select the stair, then on the Properties palette click on the cell next to the Calculation rules (on which the Tread and a small panel sign is seen now).

  10. Click in the cell to display the Calculation Rules panel in the following status.
    It is seen that only the D – Tread value can be changed.
    Click on theAutoCAD Architecture - Iconicon in the B-Riser Count line to unlock its editable mode.

  11. Pay attention that the B-Riser Count field value is set to be 18, the D-Tread value to 280 mm [11”], and then press OK to exit the panel.
    AutoCAD Architecture - B - Riser Count - 18
    During the operation the program can indicate that the values do not satisfy the calculation rules, but if the values are changed, it will be right.

  12. The Stair will be changed like in the figure. The next step is to move the stair to its place.AutoCAD Architecture - Move The Stair To Its Place
  13. With the AutoCAD MoveAutoCAD Architecture - Move Commandcommand move the stair from the ENDpoint to the ENDpoint, so the right bottom corner of the stair fall in the suitable wall corner.

    The next step is to turn on visibility of steps above the Cut Plane.
  14. Select the stair and open the Stair Style panel with the Edit Style command from the Ribbon contextual Stair tab. Go to the Components tab and turn off the Sloping Riser, and turn on the Tread and the Riser.
    AutoCAD Architecture - Go To The Components
  15. Then go to the Display Properties tab, and then in the Plan High Detail line turn on the Style Override option. On the displayed Display Properties panel the next is to turn on the visibility of the Riser above cut plane on the Layer/Color/Linetype tab, and the visibility of the Path above cut plane. As the Riser Component has been switched on just now, it is not seen in the list of the Display Component. In this case you have to close the panel with OK, and then you can go again to the Stair Style panel and you can turn on visibility of Riser above cut plane and Path above cut plane, because now they are seen in the list. Finally please close the panel with OK.
