Steel Stairs
This command is used to place in the scene a steel staircase assembly consisting of steps, side elements and landing platform.
Drag the command into the scene and set the options, to dimension the scale you can drag the handles of the preview or enter the values in the dialog.

The dialog is divided into four sections:
Stair Geometry
In the first section, you can set the overall dimensions of the stair (or you can drag the handles in the preview).
Lateral Elements
In the second section, it is possible to select the type of the lateral elements of the staircase, the size, the placement (both, only right, only left), and the position (inside or outside of the size); with the first icon you change the Steel Type, while with the second icon you can use a custom steel (how to create custom steel)
when you choose to use custom steel profiles, the drop-down button for choosing the profile appears, a button also appears to set the size.
Step
In the third section, it is possible to select the type of stairs steps, the size, the offset with respect to the side elements and the minimum climb between the steps (or - slightly above - force the number of steps);
with the info icon you can display a diagram for the correct sizing of the staircase.
Landing
The fourth section is for the setting of the landing plate, it is possible to select the type (Straight, Right, Left or Centered) and set its size.
Library Folders
The first icon at the top left of the dialog opens the dialog for setting the folders of the Steel Stairs library: in these folders it is possible to save the custom elements such as laterals, steps, landings and railings.
Custom elements
In order to adapt elements to the chosen dimensions, all the models that make up the staircase must be parametric, and be saved in the respective folders of the library.
Here are two examples of Lateral Elements:
Lateral1 is a part with a front parametric section:
in order to adapt to the size of the staircase, the lateral elements must contain these parameters:
- StairLength - corresponds to L of the stair geometry, is the length of the stair
- StairHeight - corresponds to H of the stair geometry, is the height of the stair
- Width - corresponds to W of the profile, it is the width of the Lateral Elem
- Height - corresponds to H of the profile, is the height of the Lateral Elem
- Thickness - corresponds to Th, is the thickness of the Lateral Elem
- FrontalModel - equal to 1, indicates that the parametric section is in front (and therefore it is not the section of the custom steel)
Lateral2 is a part with lateral parametric section (section of the custom steel):
in this case the parameter Length (of the profile) does not correspond to the length of the stair, but is used to calculate the hypotenuse between the Length(L) and Height(H) of the stair.
- Width - corresponds to W of the profile, it is the width of the Lateral Elem
- Height - corresponds to H of the profile, is the height of the Lateral Elem
- Thickness - corresponds to Th, is the thickness of the Lateral Elem
- C - corresponds to C, is the size of the flange of the Lateral Elem
Here are two examples of Steps:
Step03_SM is a SheetMetal part:
to be able to adapt to the size of the staircase, the steps must contain these parameters (at part or assembly level):
- Width - corresponds to W of the stair geometry, is the width of the stair
- Depth - corresponds to d of the step, it is the depth of the step
- Thickness - corresponds to th, is the thickness of the step
optional, only if there are screws
- ScrewOffset - distance of the screw from the edge of the step
Step06-S_Bolt is an Assembly of a Step with Grid (simplified) and bolts, nuts and washers:
