This is where you enter the dimensions in the unit currently set. The preview provides additional support.

Flip flight direction

You can flip the direction in which the line of travel is created (you can still correct this setting when it comes to placing the stair in the workspace).

Height, rise and number of steps

You can define the Height, Rise and Number of steps as follows:

• Number of steps based on tread-to-riser ratio
  You can enter the height at the top and bottom of the stair.
• Based on the difference in height (you can enter the rise number and the height at the top and bottom of the stair)
• Based on the rise (you can enter the rise and the rise number; the system calculates the height at the top of the stair)
• Select the Create top step at height of slab check box to create the top step at the height specified for Height (top).
• The width of tread is calculated from the other settings.

Components

Tread, riser

If you want to apply treads and/or risers to the stair, select the relevant check boxes and enter appropriate values.

Components

You can create stairs with treads and risers only, concrete stairs (with or without treads), stairs with stringers and stairs with handrails. Select the relevant check boxes and enter appropriate values.

Visible / hidden component lines

You can define the Format properties (Pen, Line and Color) that are used to display visible and hidden component lines. The layer currently set on the Format toolbar is used for the entire stair, and the line of travel is created with the settings that are currently set on this toolbar.

Match all components from an existing stair

Select this option and click to match all the components from a stair you have already placed.

Note: When this option is selected, you cannot make any settings in the Stair components area (in the right hand part of the dialog box); the settings available in the Stair shape, plan dimensions and Height, rise and number of steps areas can, however, be modified.

Restore section in plan (for modifications only)

This option is only available when you have created a section of the stair to be modified. Select this option if you want to retain the section.
