Laying Mode by Profiles

 

 

 

This method allows you to create a staircase by selecting a treading profile and edge profiles directly in the graphic area.

 

 

 

  • The Z axis of the absolute frame must represent the vertical of the created staircase.

 

 

Creation stages / Use:

 

 

 Select the  Profiles mode to place the command in profiles mode:

 

  • Heigth to cross: distance between the floor and the landing.
    It is possible to give this     Length or to select a Point in the graphical environment to determine this height in relation to the destination frame.

 

  • Objective treading profile: This profile makes it possible to deduce the theoretical dimensions of the staircase.

    • The lines correspond to the flights, the arcs to landings.

    • Two consecutive lines allow the inclusion of a Classic landing between two flights.

    • The profile is oriented, which defines the direction of ascent.

 

 

  • The profile must be created in an XY plane, not necessarily absolute.

  • It must be G1 continuous and contain only lines and arcs.

 

 

  • Trimming profiles:

    • The theoretical staircase is then limited by the two chosen edge profiles.

 

 

  • The trimming profiles must be created in an XY plane, the same as the plane of the of the treading profile.

  • The profiles must allow the limitation of treads. If the treads cross each other, it will not be possible to create the staircase in 3D!

    The center of the spiral treads is inside the two limiting profiles. The treads cross each other, so they cannot be built in 3D.

    The center of the spiral treads is outside the two limiting profiles. The treads not cross each other, so they can be built in 3D.

 

 

 

 

 

  • Computing mode: affects the way in which the treads are dimensioned. See the Computing mode section for more information.

  • On each flight:

    • The length and width parameters of each flight are automatically calculated via the treading profile, so they are not displayed.

    • Only the distribution of the residual is to be defined in the same step mode.  

 

 

  • The landings are initialized when the staircase is created to have a calculated treading line calculated as close as possible to the selected treading profile.

  • In the standard case of alternating lines and arcs:

    • If the radii are the same, the landings are initialized as winder.

    • If the radii are different, the landings whose radius corresponds to the minimum radius are winder, the others are spiral.

  • If two lines are consecutive, the landing is initialized as a classical bearing.

  • If two circles are consecutive, the bearings are initialized as spiral.

 

 

  • The parameters of each landing can be changed after initialization.
