階段ツール

概要

Test

The Stair tool is a powerful tool that allows you to add a custom flight of stairs for your project in just two clicks. You can change the default stair settings as required. The Stair tool will automatically try to fit these requirements. It is possible to create single-flight straight, double-flight L-shaped, and double or triple-flight U-shaped stairs.

直線状の階段を作成する

  1. Select the Stair tool from the Quad (1).


  2. スラブの上にカーソルを合わせてみてください。階段のカーソル(2)が表示され、階段カーソルが乗っているスラブがハイライト表示されます。これは最初のステップの位置を示しています。カーソルの位置が無効な場合は、カーソルが赤く(3)なります。




  3. To flip the direction of the first step, choose the Flip option or type F in the command line.

    To turn the direction of the first step 90°, choose the Quarter-turn option or type Q.

    To cycle through the different stair types, use the Ctrl key when the Hotkey Assistant is active.
    Note: The cursor will automatically flip or quarter-turn when it is positioned close to a wall or the edge of a slab. This auto-quarter-turning/flipping behavior is only active when the Automatically flip/quarter-turn option is activated.
  4. Once the cursor is in position, left-click with the mouse. If the upper slab is blocking the view, the slab will become transparent.


  5. まっすぐな階段を作るには、マウスを最初のステップに垂直に置きます。
    Note: A live preview of the flight of stairs to be created (blue) will follow the mouse dynamically (6). The Stair tool will automatically snap to the configurations that correspond to the Preferred tred length setting. When the optimal configuration is satisfying, this preview will display in a darker shade of blue. The other settings are taken into account as well, but not to this specific snapping feature (where the stair preview turns darker blue).


  6. Once you have the cursor in the correct position, left-click. A flight of stairs will be created. A hole is automatically generated in the upper slab, corresponding to the Head room setting (7).


L字型階段を作成する

  1. Select the Stair tool from the Quad.
  2. スラブにカーソルを合わせます。階段カーソルが表示されます。階段カーソルが正しい位置になったら左クリックします。
  3. カーソルを垂直方向から離して、L字型の階段(8)を作ります。


    Note: A live preview of the flight of stairs to be created (blue) will follow the mouse dynamically (8). The Stair tool will automatically try to find optimal configurations of the stair that correspond with the dimensions given in the Stair dialog. It will snap to the optimal configuration and display this preview in a slightly darker color.
  4. When you are satisfied with the preview, left-click. A flight of stairs will be created and a hole will be automatically generated (9). This time, the hole can be L-shaped, depending on the length of the upper flight and the Head room stair setting. If the head room is so large it cannot be covered with only the topmost stair flight, it will span also a part of the second stair flight and thus be L-shaped.


U字型階段を作成する

  1. Select the Stair tool from the Quad.
  2. スラブにカーソルを合わせます。階段カーソルが表示されます。階段カーソルが正しい位置に来たら左クリックします。
  3. Move the cursor away. Type Q and Enter to rotate the direction of the second cursor 180° with respect to the first cursor.

Or use the Ctrl key when the Hot Key Assistant (HKA field in the Status bar) is ON.

  1. Select the Stair tool from the Quad.
  2. Hover over a slab. The Stair Cursor appears. Left-click when the stair cursor is in the correct position.
  3. カーソルを垂直の部分から遠ざけると、L字型の階段になります。
  4. Press the Ctrl key to switch between an L-shaped stair and a U-shaped stair.

    Or align the last step with the first fixed step. When entering a strip parallel to the first step, the last step will automatically quarter turn.



    Note: A live preview of the flight of stairs to be created (blue) will follow the mouse dynamically (10). The Stair tool will automatically snap to the configurations that correspond to the current settings. When the optimal configuration is satisfied, this preview will display in a darker shade of blue.
  5. U字型階段は、下記の2種類を切り替えることができます：
    • 中間部にステップ(10)がある場合。
    • 中間部が対向する2つの階段(11)の踊り場になる場合。

    It is possible to switch between these two modes by typing U and hitting Enter.

    Or press Ctrl to cycle between different stair variants.



既存の開口部に階段を作成する

Sometimes it is necessary to create a flight of stairs starting from the edge of a slab, where an opening already exists.



In the example above, different floors need to be connected with flights of stairs. However, an opening does not need to be created.

  1. Select the Stair tool from the Quad.
  2. Hover the Stair Cursor near the edge of the slab (12). The cursor automatically snaps to the outer side of the edge.


  3. 上記のように階段のフライトを作成します。


  4. You can also make a flight of stairs by starting at the lowest point. Select a starting point on the first floor (13).


  5. Hover over the edge of the slab on the second floor. The Stair Cursor automatically snaps to the edge of this slab. Left-click to create the flight of stairs.


階段の編集

You can adjust multiple parameters of a flight of stairs created with the Stair tool in the Properties panel. These parameters include:



Height_Staircase The overall height of the flight of stairs. The height is fixed at the top and is adjusted from the base.
Stair_Width The width of the flight of stairs. When a flight of stairs is selected, a green dot appears on the upper slab. This dot indicates the insertion point of the flight of stairs. When this point is in the middle of the flight of stairs, the flight of stairs will widen from the center. When it is located at the side, for example when a stair is attached to a wall, the stair will only widen the side away from the dot.
Ideal_Riser_Height The ideal riser height. When creating a flight of stairs, the real riser height will be calculated based on the ideal riser height and the height of the steps, so that the risers are equally divided as close to the ideal riser height as possible.
Step_Thickness The step thickness. The upper face of the steps is fixed so that the thickness increases downwards.
Nosing 後続のトレッド間の重なりの水平距離。
Length_StairFlight_0 The length of the first flight of stairs. Decreasing this value will shorten the length. The length of the treads and the number of treads for each flight will be updated according to the total length of all the flights of stairs.
Length_StairFlight_1 The length of an optional, second flight of stairs. Decreasing this value will shorten the length. The length of the treads and the number of treads for each flight will be updated according to the total length of all the flights of stairs. This option is only available for L-stairs and U-stairs.
Length_StairFlight_2 The length of an optional third flight of stairs. Decreasing this value will shorten the length. The length of the treads and the number of treads for each flight will be updated according to the total length of all the flights of stairs. This option is only available for U-stairs.
Landing_Extension_Up The length of the landing going down the first flight of stairs. The first flight is fixed so the second flight adjusts to the given parameter value.
Landing_Extension_Down The length of the landing going down the second flight of stairs. The first flight is fixed so the second flight adjusts to the given value.


Setting: Landing_Extension _Up.



Setting: Landing_Extension_Down.

You can re-position a flight of stairs created with the Stair tool using the MOVE command.

For complex edits to a flight of stairs created with the Stair tool, use the BEDIT command to edit the block definition. When in the BEdit-mode, navigate to the Mechanical Browser. Here you can see and edit all the constraints that apply to a flight of stairs.
