Situation |
Description |
---|---|
|
Stairs with wooden steps. Vertical bottom landing type. |
|
Stairs with C-shaped stringers. Horizontal bottom landing type. Wooden steps are bolted to steel brackets. |
|
Stairs with stringers notched to the supporting beam. |
Before you start
If the stringers are notched to bear on the supporting beams, 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.
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.

Top landing type
Option | Description |
---|---|
Default |
|
Horizontal landing |
|
Notched The stringer top is on the supporting part. Vertical and horizontal plates are welded at the end of the stringer. |
Bottom landing type
Option | Description |
---|---|
Default |
|
Vertical Creates a vertical landing where the lower picked point is on the top plane of the last step. |
|
Horizontal Creates a horizontal landing where the lower picked point is on the top plane of the last step. |
|
Vertical lowered point The picked point is at the top of steel or finish floor. |
|
Horizontal lowered point The picked point is at the top of steel or finish floor. |
|
Notched Creates a notch to the bottom of the stringer to bear on the supporting part. A vertical plate is welded at the end of the stringer. |
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 upper 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 |
Define this dimension based on the selected bottom landing type:
|
150 mm |
5 |
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 |
6 |
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 |
7 10 |
Define this dimension based on the selected bottom landing type:
|
600 mm |
8 |
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 |
9 |
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 |
11 |
Define the width of the steps. |
0 mm |
12 |
Define the dimension to shorten the steps equally on both sides. |
1000 mm |
13 |
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 |
14 |
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 |
15 |
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 |
16 |
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 |
17 |
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, Wooden steps pan (S72) creates the number of steps you have defined. |
Calculated from the vertical distance between the 2 picked points and the spacing between steps (3) |
Stair setup 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.
