Standard Stair - General Parameters tab

Used to specify the overall stair geometry as well as configuration of top and bottom stair ends.
SettingDescription
Stair Width Sets the width of the stairs.
Insert Stair On Top When checked, uses the selected insertion point as the top of the stair case.
Nosing Offset Sets the offset distance between the top of the stringer shape and the front corners of the stair nosing. This distance is measured perpendicular to the stringer.
Create Groups When checked, forms groups for objects in the stair.
Dog Legs as Main Part When checked, uses the Dog Legs as the main part of the stair group.
Stringer Shape Displays the shape size for the stair stringers selected using the (Select Shape tool).
Create WorkFrame When checked, creates a workframe for the stair treads.
WF Name Prefix Enter a text prefix to use for the stair workframe (when the Create WorkFrame option is set).
Middle Landing Thickness Sets the thickness/depth of the middle landing grating.
Front Clip Dist. Sets the distance value from the workframe edge to the front of the tread clips.
Rear Clip Dist. Sets the distance value from the workframe edge to the rear of the tread clips.

Stair Bottom

SettingDescription
Stair Run Bottom Activates one of the two options available to use at the bottom of the stair run:
  • With Bottom Landing – The stair has a landing at the bottom using the indicated landing parameters.
  • With Bottom Cut – The stringers are cut as indicated a the bottom (no landing).
Refer to the dynamic illustration for details on the selected type using the Show Preview button.
With Bottom Landing Activates the landing type and shape settings
  • Landing Type – Sets one of the predefined landing configurations from the drop-down list.
    • Type A – Activates support member's shape size and settings.
  • Support Shape – Displays the shape size for the currently selected support member.
    • (Select Shape tool) – opens Shape Selection dialog where desired shape size is selected.
  • Start Shape – When checked, use sa start support shape at the front of the bottom landing.
  • Back Shape – When checked, uses a back support shape at the start of the stair bottom (i.e., beneath the upper end of the stringers). Activated for Landing Type A only.
  • Start Miter Cut – When checked, uses a miter cut between the landing stringers and the start support shape.

    When unchecked, the start support shape is cut at the face of the landing stringers (front of the landing).

  • Leg Miter Cut – When checked, uses a miter cut between the stair stringer and the landing stringer.

    When unchecked, the landing stringers are cut at the face of the stair stringer vertical end.

    Activated for Landing Type B only
With Bottom Cut
  • Activates bottom cut settings:
    • Cut Type – Sets one of the predefined stringer cut configurations from the drop-down list. The necessary inputs for the selected type are active fields on this tab (other inputs are made inactive).
    • Riser Start – When checked, starts the stair run at the height of a riser. When unchecked, the stair run starts at the elevation of the selected insert point.
Grating
  • Side Offset – The distance the side edges (i.e., over the landing stringers) should extend over the landing stringers. Use a negative offset to create a gap between the stringers and the side edges of the grating.
  • Fr Edge Offset – The distance the back edge of the grating (i.e., over the back support) should extend over the back support (if Start Shape is set) or the end of the landing stringers.
  • Ba. Edge Offset – (for Landing Type B only) The distance the back edge of the grating (i.e., over the back support) should extend over the back support (if Back Shape is checked) or the end of the landing stringers.
  • Thickness – Sets the thickness of the grating used for the lower landing.
Input A, B, C, D Sets the user inputs to the active dimension field. These dimensions vary based on the selection of landing or cut and the type of landing or cut selected. (Refer to the dynamic illustration preview pan to relate the input dimensions).
Plate Activated for bottom cut Type C only. Sets the dimension in respective fields. The plate dimensions are used to define the base plate shape for the stair stringer.

Stair Top tab

SettingDescription
Stair Run Bottom Activates one of the two options available to use at the top of the stair run:
  • With Bottom Landing – The stair has a landing at the top using the indicated landing parameters.
  • With Bottom Cut – The stringers are cut as indicated a the top (no landing).
Refer to the dynamic illustration for details on the selected type using the Show Preview button.
With Bottom Landing Activates the landing type and shape settings
  • Landing Type – Sets one of the predefined landing configurations from the drop-down list.
    • Type A – Activates support member's shape size and settings.
    • Type B – Activates back support settings including miter cuts.
  • Support Shape – Displays the shape size for the currently selected support member.
    • (Select Shape tool) – opens Shape Selection dialog where desired shape size is selected.
  • Start Shape – When checked, use sa start support shape at the front of the top landing.
  • Back Shape – When checked, uses a back support shape at the start of the stair top (i.e., beneath the lower end of the stringers). Activated for Landing Type A only.
  • Back Miter Cut – When checked, uses a miter cut between the landing stringers and the back support shape.

    When unchecked, the back support shape is cut at the face of the landing stringers (front of the landing)

With Top Cut
  • Activates top cut settings
    • Cut Type – Sets one of the predefined stringer cut configurations from the drop-down list. The necessary inputs for the selected type are active fields on this tab (other inputs are made inactive).
    • Riser Start – When checked, starts the stair run at the height of a riser.
Grating
  • Side Offset – The distance the side edges (i.e., over the landing stringers) should extend over the landing stringers. Use a negative offset to create a gap between the stringers and the side edges of the grating .
  • Edge Offset – The distance the back edge of the grating (i.e., over the back support) should extend over the back support (if Back Shape is checked) or the end of the landing stringers.
  • Thickness – Sets the thickness of the grating used for the upper landing.
Input A, B, C, D Sets the user inputs to the active dimension field. These dimensions vary based on the selection of landing or cut and the type of landing or cut selected. (Refer to the dynamic illustration preview pan to relate the input dimensions).
