Stair Type Parameters
Select the stair type from the list in the Stair type tab
of the Stair Tool dialog box. The parameters you can select depend
on the stair type.
General
parameters
- Storey
height - The default storey height (h) is loaded from
the project parameter Default Stairs Height (STAIRS_HEIGHT).
- Width - With this parameter, you can set the width of
all flights to be the same. After this, you can separately change
the width of individual flights. The final stair
dimensions depend on the string type and string width.
- Length 1, 2 3 - Flight lengths according to the stair
type. The final stair dimensions depend on the string type and
string width.
- Straight Stairs
- L Stair
- U Stair
- Z Stair
- Landing depth - Landing depth (d). You can change the
landing dimensions in the angle settings.
- Angle - Angle of curved stair (a).
- Inner radius - Inner radius of curved stair (r).
Run line
parameters
- 1./2./3. flight step count - Number of steps in an
individual flight.
- Step
count - The program calculates the total number of steps
in all flights.
- Run (a)
- Rise (b)
- 2x rise +
run - The program calculates the dimensioning reference
value. The limiting values can be defined in the system settings
with the stair_design_limits keyword. Default is 600 - 650 mm.
Angle settings
- 1. corner step - The first step of a corner that is not
a fixed-width straight step. Enter the serial number of the step in
the text field. For example, the stair below has two corners. The
first corner step of the first corner is step number 3, and the
first corner step of the second corner is step number 9. In the
preview image, the corner steps are drawn in red.
- Last corner step - The last step of a corner that is not
a fixed-width straight step. Enter the serial number of the step in
the text field. For example, the stair below has two corners. The
last corner step of the first corner is step number 8, and the last
corner step of the second corner is step number 14. In the preview
image, the corner steps are drawn in red.
- Right side radius - The radius of curvature (r1) of the
right corner when going up the stair.
- Left side radius - The radius of curvature (r2) of the
left corner when going up the stair.
- Run line radius - The radius of curvature of the run
line in the corner.
- Landing length 1, 2 - The landing dimensions in the
corner.
- Landing right side depth - The inside dimension (3) of
the landing with the stair type UV landing stair.
Flight settings
- 1./2./3. flight width - The initial value is the same as
the value of the parameter Width. If necessary, enter the
new width in the text field.
Other parameters
- Run line location - In spiral stairs, a run line is the
line at which the step run is a value according to the Run
parameter. The flight width is multiplied by the parameter in order
to obtain the distance of the run line from the edge of the stair.
Changing the parameter influences the stair dimensions.
- Start angle - The angle (a1)
of the front edge of the first step.
- End angle - The angle (a2) of
the rear edge of the last step.
- 1./2./3. flight angle - The angle of the flight in
relation to the upright.
- 2D drawing layer - You can define the layer of the
stair's 2D geometry in two ways:
- Reflection is mirrored - This parameter has an effect
only if the cut line (A) has been selected to be visible in the
stair's 2D geometry. By default, the geometry of a reflected stair
is not mirrored (B). If you wish to mirror the geometry of a
reflected stair, select Yes from the list. In this case, the
lines below the level defined by the cut line are drawn in
reflected geometry according to the properties defined in the
settings (C).
- Cutline visibility - Show (A) or hide (B) the cutline in
the stair's 2D geometry.
- Cutline location - The cutting height which determines
the location of the cutting line in the stair's 2D geometry.
- Arrow size - The size of the arrow pointing the
direction of the stair in the stair's 2D geometry. May have the
value 0..1. With value 1, the arrow is of the width of the stair.
- Run line
length - The program calculates the total run line
length.
- Step tool program -
The application development program which adds step numbers to the
stair's 2D geometry. Several programs can be used for different
stair types. The program must be located in the ../macros/triggers
folder.
- Stair tool program - The application development program
which adds stair data, such as rise, run, number of steps and
landings, to the stair's 2D geometry. The program must be located
in the ../macros/triggers folder.
