To change type properties, select the stairs and click Modify tab
Properties panel
(Type Properties). Changes to type properties apply to all instances in the project.
| Name | Description |
|---|---|
| Construction | |
| Calculation Rules | Click Edit to set the stair calculation rules. See Using the Stair Calculator. |
| Extend Below Base | Extends stringers below the base level of the stair. This is useful for cases where the stringer attaches to the face of a floor opening rather than resting on the surface of a floor. To extend the stringer below the floor, enter a negative number. |
| Monolithic Stairs | Specifies that the stairs are to be made of one material. |
| Landing Overlap | Enabled when stairs are set to monolithic. When a monolithic stair has a winder, the bottom of the stair can be a smooth shape or stepped. If it is stepped, this parameter controls the distance between the riser face and the vertical face of the corresponding step on the underside. |
| Underside of Winder | Enabled when stairs are set to monolithic. If a monolithic stair has a winder, the bottom of the stair can be a smooth shape or stepped. |
| Function | Indicates whether the stairs are interior (default value) or exterior. Function is used in scheduling and to create filters to simplify a model when exporting. |
| Graphics | |
| Break Symbol in Plan | Specifies whether the cutline of the stairs in plan view has a break line. |
| Text Size | Changes the size of the UP-DN symbol in a plan view. |
| Text Font | Sets the font of the UP-DN symbol. |
| Materials and Finishes | |
| Tread Material | Click the button to open the Material Browser. See Materials for more information on creating a material. |
| Riser Material | See Tread Material description. |
| Stringer Material | See Tread Material description. |
| Monolithic Material | See Tread Material description. |
| Treads | |
| Minimum Tread Depth | Sets the initial value for the Actual Tread Depth instance parameter. If the Actual Tread Depth value exceeds this value, Revit issues a warning. |
| Tread Thickness | Sets the thickness of the tread. |
| Nosing Length | Specifies the amount of the tread depth that overhangs the next tread. |
| Nosing Profile | The profile for a sweep added to the front of the tread. See Creating a Profile Family. Also see Creating a Sweep. Revit has predefined profiles to use for the sweep. |
| Apply Nosing Profile | Specifies 1-sided, 2-sided, or 3-sided tread nosing. |
| Risers | |
| Maximum Riser Height | Sets the maximum height of each riser on the staircase. |
| Begin with Riser | If selected, Revit adds a riser to the beginning of the stairs. If you clear the check box, Revit removes the beginning riser. Note that you may receive a warning about the actual number of risers exceeding the desired number of risers if you clear this check box. To resolve this, either select End with Riser, or change the desired number of risers. |
| End with Riser | If selected, Revit adds a riser to the end of the stairs. If you clear the check box, Revit removes the end riser. |
| Riser Type | Creates straight or slanted risers, or no riser. |
| Riser Thickness | Sets the thickness of the riser. |
| Riser to Tread Connection | Switches the connection of the riser and tread in relation to each other. The riser can extend behind the tread, or the tread can extend under the riser. |
| Stringers | |
| Trim Stringers at Top | Trim Stringers at Top affects the top end of stringers on a stair run. If you select Do Not Trim, the stringer is cut with a single vertical cut resulting in a point at the top. If you select Match Level, the stringer is cut horizontally, making the top of the stringer flush with the top level. If you select Match Landing Stringer, a horizontal cut is made at the same height as the stringer top on landings. To see the effects of this parameter clearly, you may want to clear the check box for End with Riser. |
| Right Stringer | Sets the type of stringer for the right side of the stairs. None means there is no stringer. A closed stringer encases the treads and risers. An open stringer exposes the treads and risers. |
| Left Stringer | See description for Right Stringer. |
| Middle Stringers | Sets the number of stringers that appear underneath the stairs between the left and right of the stairs. |
| Stringer Thickness | Sets the thickness of the stringers. |
| Stringer Height | Sets the height of the stringers. |
| Open Stringer Offset | Enabled when the stairs have an open stringer. Moves an open stringer from side to side. For example, if you offset an open right stringer, it moves toward the left stringer. |
| Stringer Carriage Height | Controls the relationship between the side stringers and treads. If you increase the number, the stringer moves down from the treads. Treads do not move. Railings do not change height relative to treads, but the balusters extend down to meet the stringer top. This height is measured from the tread end (lower corner) to the bottom side of the stringer, perpendicular to the stringer. |
| Landing Carriage Height | Allows stringers to have a different height relationship to landings than they do to sloped runs. For example, it lowers a horizontal stringer toward a landing on u-shaped stairs. |
| Identity Data | |
| Type Mark | A value to designate the particular stairs. Useful if you need to identify more than one set of staircases. This value must be unique for each stairway in a project. Revit warns you if the number is already used but allows you to continue using it. (You can see the warning using the Review Warnings tool. See Reviewing Warning Messages.) |
| Keynote | Adds or edits the stairs keynote. Click in the value box to open the Keynotes dialog. See Keynotes. |
| Model | The model type for the stairs. May not be applicable. |
| Manufacturer | Manufacturer for the stair materials. May not be applicable. |
| Type Comments | Specific comments on the stair type. |
| URL | A link to a web page for the manufacturer or other appropriate link. |
| Description | A description for the stairs, such as circular. |
| Assembly Description | Description of the assembly based on the assembly code selection. |
| Assembly Code | Uniformat assembly code selected from hierarchical list. |
| Cost | Material cost. |
