Modify stair component shape and location by dragging controls.
After you select the stair for editing, and select a stair component, modification controls are available for direct manipulation of the component.
Control | Modification Behavior |
---|---|
1 | Drag the filled dot control (at the open run end) to reposition the end of the run and to add or remove treads/risers in any direction. (You cannot add treads/risers below the base level of the stair.) |
2 | Drag the arrow control at the run end along the stair path to add or remove steps. Modifying the run end with the arrow control maintains the stair height. |
3 | Drag the arrow shape control at one of the run edges to change the width of the run. |
4 | Drag the arrow control to modify the leg length of the landing where it is connected to a run. You can also use this control on landing edges to resize the landing. |
5 | Drag the square control on a winder run leg to move the leg. Winder steps are added/removed from the winder legs in the run to maintain the original stair height. |
6 | Drag the hollow dot control at the middle of a spiral run to change the radius. |
Moving a run repositions the run by a multiple of the riser height value. Connected components, such as an automatic landing, stay joined, and the height of the stair assembly is maintained.
Select the run component, and drag it to the new location. In the following example, the run is moved to the left.
You can add or remove treads/risers from an open end of a run. If you add steps to the open end of the top run, they will be above the top elevation of the stair. Notice that the riser index number indicates + and the number of steps added.
Select the run component, and drag the filled dot control to add or remove treads/risers. In the following example, 3 steps were added to the top of the run.
Rotate a run by dragging the filled dot control at the end of a run (or by using the Rotate tool on the Modify panel).
Select the run component, and drag the filled dot control (at the open end) to rotate the run. If the run is connected to an automatic landing, the landing shape is adjusted to accommodate the new run angle.
You can balance the number of steps in a run, such as a winder run or spiral run, by manipulating one end of the run. The original stair height is maintained, but the configuration of steps changes.
Drag the arrow shape handle at one end of the run to change the configuration of the steps. In this example, the right winder leg is lengthened and the adjacent legs adjust so that the stair height is not changed.
You can reposition a leg in a winder run. Other legs in the winder run will remain in the same position, but steps will be added or deleted from the connected winder legs to maintain the original stair height.
One way to adjust a stair to meet the headroom clearance requirement is to modify the landing height. Other methods include repositioning a run and balancing the number of treads/risers between runs.
To adjust the landing height, In an elevation view, select the landing, and use the Move tool to change the landing position. (You could also modify the Height instance property for the landing). Notice that the steps adjust between the runs to accommodate the landing height change.
You can change the width of a run directly in stair assembly edit mode.
Select the run, and drag the arrow shape control at one of the run edges to change the width. Notice that the width of the connected landing component changes as well.
You can modify the shape of an automatic landing while keeping the runs connected as designed.
Select the landing, and drag the arrow shape controls at the edges to modify the landing size and shape.
