Use this procedure to create a multi-landing stair. You can use multi-landing stair shapes to define both straight and angled stair runs. You can insert quarter-landings, half-landings, and turns.
This type of stair is constrained by the design rules on the stair and the floor-to-floor height.
If you are drawing the risers or flights of a stair, lines for each tread are shown. If you are drawing a flat landing, no tread lines are shown. If you are drawing a turn-type landing, angled tread lines are shown through the turn. These temporary lines do not necessarily represent the actual locations of tread lines in the final stair. In addition, the number of risers currently added to the stair is displayed (to the left of the stair), as a fraction of the total number of risers required for the stair; for example, “10/18.”
Note: To create a straight stair with user-specified landings, use the multi-landing shape with half-landings. Select all the points in a straight line to define the flight start points and flight endpoints.
Creating a multi-landing stair with 1/4 landings
Tip: To ensure that the Properties palette is displayed before you select a tool, click 
Properties.
Properties. - Open the tool palette that you want to use, and select a stair tool.
If necessary, scroll to display the tool that you want to use.
Note: Alternatively, click. 
- On the Properties palette, click the Design tab, expand Basic, and expand General.
- Select a style.
- For Shape, select Multi-landing.
- Specify the turn type:
If you want to… Then… create a flat landing with a user-defined length where the stair run turns select 1/2 landing for Turn type. create stairs with a user-defined length where the stair run turns with treads through the turn select 1/2 turn for Turn type. Note: These stairs must have at least three segments and each corner must turn in the same direction.create a flat landing where the stair turns, with the length of the landing equal to the width of the stair select 1/4 landing for Turn type. Note: These stairs typically have two or more flights joined by square landings.create stairs having treads along the entire length, with one or more turns in any direction select 1/4 turn for Turn type. Note: These stairs may have two or more segments, and corners may turn in either direction. - Specify the vertical orientation of the stair:
If you want to… Then… draw the stair from this floor to the floor above select Up for Vertical Orientation. draw the stair from this floor to the floor below select Down for Vertical Orientation. - Expand Dimensions.
- Specify stair width, height, and justification:
If you want to… Then… specify the width of the stair enter a value for Width. specify the height of the stair enter a value for Height. specify the justification of the stair enter a value for Justify. The Justify value controls the insertion point when you place the stair (left, center, or right) at the beginning of the stair run. - Specify the stair termination:
if you want to… then… end the stair run with a riser select Riser for Terminate with. 
Note: Stairs that end with a riser will have an overall height that is one tread thickness less than the floor-to-floor height specified.end the stair run with a tread select Tread for Terminate with. 
end the stair run with a landing select Landing for Terminate with. 
- Click
next to Calculation rules, and
if you want to… then… specify the overall linear length of the stair enter values for Straight Length and Riser Count, then click OK. - When Straight Length is set to
(automatic), the value is calculated based on the tread size and riser count. - When Straight Length is set to
(user-defined), the stair length is equal to the dimension entered, and the other three values are adjusted within the code limits. - When Riser Count is set to (user-defined), the tread depth is increased or decreased to accommodate the stair.
specify the total number of stair risers enter a value for Riser Count, then click OK. - When Riser Count is set to (automatic), the number of risers is based on the overall length and overall height of the stair and the code limits specified on the Design Rules tab. The Straight Length value of the stair is adjusted automatically.
- When Riser Count is set to (user-defined), you can specify a value that is used to calculate the tread depth and riser height. If these values fall outside the stair limits, an error message is displayed.
specify the height of each riser in the stair flight set all fields to (automatic), click the icon for Riser to change it to (user-defined), and enter a value for Riser. Click OK. specify the tread depth for each tread in the stair flight set all fields to (automatic), click the icon next to Tread to change it to (user-defined), and enter a value for Tread. You can also specify the Riser count when you set the tread depth. Click OK. Note: If a value is set to user-defined on the Calculation rules worksheet, it can be modified directly in the Properties palette.Note: If
is displayed next to a field in the Calculation Rules dialog box, that field can’t be changed until another field is changed from (user-defined) to (automatic). - When Straight Length is set to
- Expand Advanced.
- Specify the Floor Settings:
If you want to… Then… change the thickness of the floor finish material at the top of the stair enter a value for Top offset. change the depth of the structure at the top of the stair enter a value for Top depth. change the thickness of the floor finish material at the bottom of the stair enter a value for Bottom offset. change the depth of the structure at the bottom of the stair enter a value for Bottom depth. - Set the minimum height or number of risers in a stair flight, or specify *NONE*.
- Set the maximum height or number of risers in a stair flight, or specify *NONE*.
- In the drawing area, specify the insertion point of the stair.
You can move or hide the Properties palette to expose more of the drawing area.
- Specify the point of the first turn or landing for the stair.
- Continue specifying points for the stair. Note: If you specified Landing for Terminate with, the last point for the stair beyond the final riser defines the end of the landing.
