Sets a benchmark height for calculating riser actual height. The value sets the limits for the riser, and along with Tread depth these values determine the gate or stride of the stair.

Displays the actual height of a riser arrived from the stair calculation. It is highly dependent on the riser target height and kept near to the target height.

Displays the total number of risers calculated in the stair assembly. You can alter the number to accommodate few risers to make a stair symmetrical or to lowering the step for comfort. The change in the riser numbers recalculates riser actual height within the margin of constraints and recommends riser number.

This field also is also displayed in the placement tab.

Displays the ideal numbers of risers the stair can have. This is a calculated value of stair height by riser height.

This field is also displayed in the placement tab.

Enabled when Riser Type had set to Parametric Profile. Sets the riser profile (.PAZ) selected from the pull down menu.

• Metal_Pan_Riser.paz – Sets the default riser profile.

Sets the type of risers to use in the stair construction.

• None – Sets no physical riser leaving space and view between the treads.
• Straight Panel – Sets a perpendicular panel filling in the space between two treads for Slab type treads.
• Slanted Panel – Sets a sloped panel filling in the space between two treads for Slab type treads and the tread nosing edge side is top justified. The nosing distance determines the slope. It is the angle from the tread nose to the rear edge of the lower tread extended by the nosing distance. The panel extends underside of the tread slab.
• Parametric Profile – Enables the Riser Profile property allowing setting one of the PAZ cell files for riser profile. Sets the cross section profile of the riser. The profile origin is defined at the tread nose and gets extruded along the nosing line till the stair edges.

Riser Profile

The Parametric profile defines the cross section of the tread, normally used for pan and sanitary pan steel stairs.

Sets the thickness of the slanted and straight panel type risers, in working unit.

Riser Thickness

Remains disabled for Parametric Profile Riser type.

Sets the position of the riser with tread.

Riser above/behind Tread

• Riser Above Tread – the riser stays on the tread panel.
• Riser Behind Tread – the riser stands behind of tread.

Remains disabled for Parametric Profile Riser type.

Sets the riser family and part pair through the popped up pull down menus.

Risers family & parts - example, Part assigns matl_Stair_Riser

Family and part assignment could be done for straight/slanted panels as well as for plane and parametric profile risers. The value set through Part option overrides the native definitions of family part, if any in the profile.
