# Calculation of the stairs with a 180-degree swivel and rotary stages

drawing scale 1:

Specify dimensions in millimetres

The height of the opening Y
The length of the opening X
Width of stairs E
Total number of Steps C
Number of steps on the turn CP
Number of steps before turning P
The thickness of the treads Z

## Calculation of stairs with sweeps 180° and Rotary stages

Enter the required dimensions in millimeters

X - Aperture length stairs
Y - The height of the opening
Z - The thickness of the treads
C - Number of steps
CP - Number of steps on the turn
P - number of treads on the bottom closed

C - The total number of steps

CP - Number of steps on the turn

P - number of treads on the bottom closed
SP - Determine the position of the first degree relative to the level of the floor of the second floor.
In the first situation of upper stage located at the level of the floor of the second floor.
In the second case, the floor of the second floor is the last step. The height of the stairs will be proportionally reduced

The program automatically calculates the height and width of the steps, the angle and the size of the top and bottom of the Stringer.
On a separate drawing shows the dimensions for Rotary.
For optimal convenience stairs change number of steps.
You can generate a black and white or colored drawing.

Stair width is the width of the stairs swinging site.
