Setting the Permissible Ranges for Stair Parameters

Set the parameter ranges for stair creation.

\astrs

Set the permissible ranges for the stair parameters so that the system calculates, generates and creates the new staircase within the specified ranges.

Description

Default ranges exist for each parameter. The values of the ranges are saved by the system in a file called stairs.arc in your current directory, and is used for all further stairs in this project until modified. You may maintain different sets of values for different projects by saving them in separate directories.

The following ranges are set by this command:

Prameter	Default	Range
Formula 2H+B	0.61 to 0.65
Rise	0.14 to 0.22
Tread	0.22 to 0.32
Min/Max number of stairs in flight	3 to 17
Layer number for stairs	1	1-255
Color of staircase	1	1-16
Thickness of handrail	0.07	-
Height of handrail above stairs	1	-
Distance of handrail from edge of step	0.035
Color of handrail	1	1-255
No. of steps in winding section	3	3, 5 or 7
spiral stairs
Headroom	2.1
Angle for measuring headroom	320
Minimum width of narrow side of step	0.1

Operation

Use the pull-down menu to display the staircase dialog box. If you enter the command via the keyboard you set the parameters via a series of prompts on the input line.

The parameters and the current values are displayed. Enter a new value or press Enter to accept the current one. When you have set all the parameters they are saved by the system.

If you wish to change only certain parameters, you can type 0 and press Enter to exit without changing the remaining values (except in the distance of handrail prompt where 0 is a legal input).
