Exercise 1.4.1: Creating a Stair and Ramp

In this exercise, students will learn how to:

  • Create stairs by sketching run lines.
  • Flip a stair direction and move a stair into place.
  • Create stairs with multiple runs and complex layouts (for example, L-shaped,
    U-shaped, and curved stairs).
  • Create and modify ramps.

  • Create a new stair from the first floor of the studio to the second floor meeting space using Figure 1.4.3 and the view called Studio – Stair 3D as guides.

  • Create an L-shaped ramp with two runs and no railings connecting the deck at the first floor level to the parking area, which is 1'–9"(0.53 meters) below ground level, using Figure 1.4.4 and the default 3D view as a guide.

Exercise 1.4.2: Modeling Custom Stairs

In this exercise, students will learn how to:

  • Edit the sketch to change the stair boundary and shape of the risers.
  • Change stair and rail types.
  • Modify the steepness of a stair by adjusting the settings in the Properties palette.
  • Create and edit a spiral stair.

  • Replace the stair created in the previous exercise with a new steeper stair with only 16 risers:
    • Open the Stairs tool, edit the type properties, choose the Residential – Open Riser type, duplicate it, and rename the new type Residential – Open Riser – Steep.
    • Set the properties for this new type to allow a maximum riser height of 9" (0.23 meters) and a minimum tread depth of 9" (0.23 meters) then create a new stair using this type to replace the old one.
    • Change the railing on the stair to Handrail – Pipe.
  • Create a spiral stair with 15 risers and run radius of 2'-0" (0.6 meters) to connect the first and second floor of the residence:
    • Open the Stairs tool and duplicate the Residential – Open Riser type again, renaming the new type to Residential – Open Riser – Spiral.
    • Set the maximum riser height to 10" (0.25 meters) and the minimum tread depth to 11" (0.28 meters).
    • Using the curved run line option, try sketching a spiral stair using this type. The sketch cannot be completed, because the rotation required exceeds 360°.
    • Change the instance properties for this stair to set the Actual Tread Depth property to 10" (0.25 meters). This value will override the minimum value specified in the type properties.
    • Resketch the spiral stair using these new properties and move it to the location shown in Figure 1.4.6.

  • Change the spiral stair’s railing to Handrail – Pipe and add a center pole as shown in Figure 1.4.7 using the views First Floor – Spiral Stair and Second Floor – Spiral Stair as guides.

Exercise 1.4.3: Creating a Floor Opening

In this exercise, students will learn how to:

  • Cut an opening to allow stairs to pass through floors.
  • Calculate the head height of stairways.
  • Modify floor openings.
  • Create railings.
  • Modify the physical properties of railings.

  • Create an opening in the second floor of the residence at the top of the spiral as shown in Figure 1.4.9 and add railings of the type Guardrail – Pipe as shown in Figure 1.4.10.

Exercise 1.4.4: Creating an Elevator

In this exercise, students will learn how to:

  • Place an elevator component.
  • Add walls to enclose the elevator.
  • Cut an elevator shaft that spans all levels.
  • Provide openings in the shaft walls to access the elevator at each floor.

  • Place the Electric_Lift elevator component in the studio near the stair placed in an earlier exercise.
  • Add 6" (0.15 meters) generic walls to the first and second floors as needed to enclose the elevator with shaft walls.
  • Use the Shaft Opening tool to cut an opening from the first floor to the roof within the shaft walls and place wall openings on the south shaft wall to provide access to the elevator.
  • Add a guardrail at the edge of the second floor slab between the west exterior wall and the new elevator shaft walls. Use the view Second Floor – Elevator to see the progression of the elevator.
