Situation |
Description |
---|---|
|
Stairs with horizontal top and bottom landings. |
|
U pan profile steps with brackets. Brackets are welded to the stringers and bolted to the steps. |
Stairs with stringers notched to the supporting beam. Steps are catalogue steps. You may also use your own custom components as steps. |
Before you start
If the stringers are notched, create the supporting beams before creating the stairs.
Selection order
- Pick a point to indicate the nosing point of the first step.
- Pick another point to indicate the nosing point of the last step.
Note that the order in which the points are picked has no effect.
- Click the middle mouse button to create the stairs.
If you have selected the following notched options on the Picture tab, select the supporting beams and then click the middle mouse button.

Use the Picture tab to control the landing types, and the shape and the location of the stringers in relation to the points you pick when creating the stairs.
Top landing types
Option | Description |

Default Horizontal AutoDefaults can change this option. |
|
Vertical Creates a vertical landing where the lower point is on the top plane of the last step. |
|
Horizontal Creates a horizontal landing where the lower point is on the top plane of the last step. |
|
Vertical lowered point Creates a vertical landing where the lower point is at the top of steel or on the floor level. |
|

Stair dimensions
Description | Default | |
---|---|---|
1 |
Define the distance between the upper point and the end of the left top landing. If you set the value to 0 mm, the left top landing is not created. If you set the top landing type to notched, define the cut dimension of the horizontal plate from the stringer edge. |
0 mm |
2 |
Define the vertical distance from the upper point to the top of steel of the top landing. If the top landing is not created, the stringer top of steel is used. If you set the top landing type to notched, define the vertical distance from the upper point to the stringer top horizontal cut. |
200 mm |
3 |
Define the maximum distance allowed between two consecutive steps. The spacing between the steps is calculated using the step spacing type Exact or Equal, and the number of steps. For example, if the step height should be 200 mm, the Exact setting creates steps of exactly this height (enter the number of steps as an integer). The Equal setting creates the required number of steps from the bottom to the top, with the height calculated as close to 200 mm as possible. |
(Z*220)/(Z+220) mm, where Z is the vertical distance between the 2 picked points. |
4 |
Select the direction of the nosing dimension of the steps:
Define the nosing dimension of the steps. This dimension depends on the direction you have selected. |
Vertical 0 mm |
5 |
Define this dimension based on the selected bottom landing type:
|
150 mm |
6 |
Define the vertical dimension from the lower point to the first step. You can define this dimension when the step spacing type is set to Equal and the bottom landing type is either vertical or horizontal lowered point. |
Equal with vertical spacing between steps |
7 |
Define the cut dimension of the vertical plate from the stringer edge. You can define this dimension when the bottom landing type is set to notched. |
0 mm |
8 11 |
Define this dimension based on the selected bottom landing type:
|
600 mm |
9 |
Define the vertical gap between the lower supporting part and the stringer cut. You can define this dimension when you have set the bottom landing type to notched. |
0 mm |
10 |
Define the horizontal gap between the lower supporting part and the stringer cut. You can define this dimension when you have set the bottom landing type to notched. |
0 mm |
12 |
Define the dimension to shorten the steps equally on both sides. |
0 mm |
13 |
Define the width of the steps. |
1000 mm |
14 |
Define the horizontal gap between the upper supporting part and the stringer cut. You can define this dimension when you have set the top landing type to notched. |
0 mm |
15 |
Define the vertical gap between the upper supporting part and the stringer cut. You can define this dimension when you have set the top landing type to notched. |
0 mm |
16 |
Define this dimension based on the selected top landing type:
If you set this dimension to 0 mm, the top landing is not created. |
0 mm |
17 |
Select the step spacing type:
The spacing type controls how the vertical spacing between the steps is calculated. If you select Exact and set the bottom landing type to horizontal or vertical lower point, the steps are spaced from the upper point to the lower point. In all other cases the steps are spaced from the lower point to the upper point. |
Equal |
18 |
Enter the number of steps. This option depends on step spacing type and step spacing. If you set the step spacing type to Exact, or to Equal and the spacing distance is not defined, Stairs (S71) creates the number of steps you have defined. |
Stair set up tab
Use the Stair setup tab to control the part properties, top and bottom steps, position of the stairs on the horizontal plane, and rotation of stringers and steps.
