The new stair tools have been improved to be component based which allows us to assemble stairs using individual runs, landing and support components. We also now have the ability to use a profile for the stringers based off of structural frame profiles. The tool provides the ability for more types of stair layouts, including overlapping and winding stairs. Concrete stairs can have custom end conditions for notched or straight cuts at stair runs.
You now have the option to create a strait run, full step spiral, spiral center point, L shaped winder and U shaped winder along with sketching. Landings and runs can be created independently.

Landing
Landings: Can be created by picking runs or sketching
Stringers: Additional types can be created from the existing 2” Stringer for custom profiles, however these are a type property of the stair, so a new stair type will need to be created for each stair type with varying stringer configurations.
When drawing a strait segment you have the option to specify where you are drawing from: Right, Left or Center and you can also specify an offset and if there is an automatic landing.
When sketching the stair you will see the stair as it will look finished, not in sketch lines as we are accustomed to. Additionally once a segment is created you can directly manipulate its width, offset and justification.
Stringers can be selected independently and modified while still in sketch mode, or after the stair sketch is complete.
Drawing overlapping stairs doesn’t require any special manipulation, just sketch the runs. Winder stairs created by component can be directly manipulated to some extent using grips, or can be converted to a sketch and then modified. Spiral stairs are created by picking the location of the center of the circle and then the radius to the location line chosen.
Graphics:
Display control for various parts of the stairs has been enhanced in both object styles and visibility graphics. Terminology has changed from beyond to above.
Customization of cut marks is type based:
Stair Path arrow location and Text can be manipulated per stair
Annotation
- Annotate individual stair run, landing and supports
- Tread depth can now be tagged
- Up/down annotation can now have a transparent background
- Treads/risers can be numbered using the Stair Tread/Riser Number tag by selecting the tag tool
and a reference line on the runs.
