QUESTION
I would like to adjust how my stairs display in plan view, including properties associated with breaklines, tread overhangs, railings, and newel posts?
ANSWER
You can specify how different stair components are displayed in plan view by accessing the Staircase Specification dialog.
To control the plan display and breakline properties
- Using the Select Objects
tool, select the staircase and then click the Open Object
edit button.
In the instance that the staircase has multiple stair segments, such as switchback or L shaped staircases, select the individual stair segment.

- On the Plan Display* panel of the Staircase Specification dialog, the Display On Floor Above section controls the stair display options for the floor above.
*Applies to X17 and newer versions.

- Select Automatic to display the stair on the floor above when located under an Open Below type room, such as a Stairwell.
- Select Always to always display to stair on the floor above.
- Select Never to disable the display of the stair on the floor above.
- While still on the Plan Display panel of the Staircase Specification dialog, check the Has Breakline box.
In X16 and prior versions, access the Breakline panel instead.

- Select the breakline Style using the drop-down.
- Specify the Distance From Start, which is the distance from the front of the stair segment to the breakline, measured from the staircase's center line.
- Specify the Breakline Angle. An angle of 0 produces a breakline that is perpendicular to the sides of a straight staircase.
- Specify the Gap After Break if desired. This creates a second breakline and specifies the distance between the two. A value of 0 produces no gap.
- Specify the Break Symbol Size, which is the total height of the break symbol measured from the top corner to the bottom corner.
- The Current Floor Display section controls the appearance of the portion of the staircase located after the breakline on the floor where the stairs are drawn.
- The Floor Above Display section controls the appearance of the portion of the staircase located before the breakline, as seen from the floor above where the stairs are drawn.

- Click OK to save any changes.

Handrails draw over the top of newels and balusters. When displaying the handrail together with newels and/or balusters, use the Fill Style button to set the fill style to "None".
