Create Sloping Floor

Referring to the hierarchy, a sloping floor element must reside below an existing floor slab element.

From the Select Structural Element pane of the Building Applications window, make sure that the Floor Slab element is the CE.

On the Building tab, in the Create group, select Sloping Floor in the Create Element drop-down list.

Click Create Element to display the Create Floor Slab window.

By default in the Naming pane of the Create Floor Slab window, the application automatically populates the Name field with a name based on the project or company autonaming rules. for further information on the autonaming rules, refer to Naming for further information.

Use gaps in naming sequence

The Use gaps in naming sequence checkbox is also selected by default, the user can select which auto name is to be used. To select the:

• first available name, click first available name.

• previous available name, click previous available name.

• next available name, click next available name.

• last available name, click last available name.

The user can change the name which does not conform to the autonaming rules, to do this, type a new name into the Name field. If this name already exists, an Error window is displayed. If the name does not conform with the autonaming rules, Apply remains greyed out as long as the name is not properly entered.

Material

The Material drop-down list by default is set to Pyrocrete, the material can be changed to another suitable material. From the Material drop-down list, the user can select from a list of suitable materials.

The material is used to calculate the weight. The density of the material selected is shown in a tooltip.

Floor Thickness

The Floor Thickness can be populated in several ways:

• Enter the absolute top level (wrt World) in the Top Level field. If the thickness is locked or the value is less than the bottom level, the bottom level adapts. If the thickness is not locked, the thickness adapts.

• To select the top level click Pick Top Level. The Positioning Control window is displayed. Follow the prompt Pick Top Level (Snap) Snap: and select the top level in the graphical view. If the thickness is locked or the value is less than the bottom level, the bottom level adapts. If the thickness is not locked, the thickness adapts. If a suitable element is selected the background colour of Top Level is changed to green and the tooltip indicates the connected element.

• Enter the thickness in the Thickness field. If the thickness is locked, click Other level changes to suit thickness to unlock it.

• Click Measure Height. The Positioning Control window is displayed. The user is prompted to Height:Pick Start (Snap) Snap:, Height:Pick End (Snap) Snap: and select two graphical picks.

• Enter the absolute bottom level (wrt World) in the Bottom Level field. If the thickness is locked or if the value is greater than the top level, the top level adapts. If the thickness is not locked, the thickness adapts.

• To select the bottom level click Pick Bottom Level. The Positioning Control window is displayed. Follow the prompt Pick Bottom Level (Snap) Snap: and select the bottom level in the graphical view. If the thickness is locked or the value is less than the top level, the top level adapts. If the thickness is not locked, the thickness adapts. If a suitable element is selected the background colour of Bottom Level is changed to green and the tooltip indicates the connected element.

If the user does not want the thickness to adapt to level changes, click Thickness changes to suit levels to lock the thickness.

The default finished level is zero with respect to the level. The default screed thickness is zero. The default slab thickness is 300.

Section Specification

To copy the section of another sloping floor, click Pick profile to copy and select the other floor. To define the section, click Catalogue.

There are six steps to using this window:

• 1. Select the specification using the Specification drop-down list.

  Select the section using the Generic Type drop-down list.

  Select the size in the list of components. If the shape can be configured, there is only one component.

  Choose the alignment of the wall using the Justification, Member Line, and Joint Line drop-down lists.

For the justification of the section around the path of the wall (Justification), use one of three p-lines at bottom (BOW, CBOW or OBOW).

For the line drawn in the Draft module (Member Line), use NA.

For the connection line (Joint Line), use NA.

Enter the properties of the section using the Modify Properties window that is displayed when the user clicks on Properties. Ignore the Thickness and Rotation angle properties because these have already been entered in the main window.

Click Apply to confirm the section, then Dismiss to close the window.

Note:

The section is modified by default. If the section is the same, it is unnecessary to display this window when creating a second sloping floor.

The properties of the floor can be modified using Properties.

The user can also change the justification of the floor using the Mirror Profile.

Start / End Position

There are a number of methods available to select the start and end positions of the floor:

• Enter the values in the fields for east, north and the up in the Start Position frame. The user can also change the reference by entering the name of an existing element in the Wrt field. If the field is greyed out, click Coordinates locked to unlock it. If the direction is locked, the end position is adjusted to suit the direction. Otherwise the direction is calculated between both positions. The length is always calculated between both positions.

• Click Pick in the Start Position frame to invoke the Positioning Control window. Follow the prompt Pick Start (Snap) Snap: and select the start position in the graphical view. To avoid modifying a desired value in a field, click Coordinates unlocked to lock it. If the direction is locked, the end position is adjusted to suit the direction. Otherwise the direction is calculated between both positions. Its length is always calculated between both positions.

• Enter the values in the field for east, north and the up in the End Position frame. The user can also change the reference by entering the name of an existing element in the Wrt field. If the field is greyed out, click Coordinates locked to unlock it. If the direction is locked, the start position is adjusted to suit the direction. Otherwise the direction is calculated between both positions. The length is always calculated between both positions.

• Click Pick in the End Position frame to invoke the Positioning Control window. Follow the prompt Pick End (Snap) Snap: and select the end position in the graphical view. To avoid modifying a desired value in a field, click Coordinates unlocked to lock it. If the direction is locked, the start position is adjusted to suit the direction. Otherwise the direction is calculated between both positions. Its length is always calculated between both positions.

• Enter the value of the length in the Length field to invoke the Positioning Control window. The end position is adjusted to suit the new length. The user is prompted to Measure Length:Pick Start (Snap) Snap:, Measure Length:Pick End (Snap) Snap: and select two positions in the graphical view. The end position is adjusted to suit the new length.

• Enter the values in the Direction fields. The direction is in the following form:

  <Cardinal point> [<Angle> <Cardinal point>[[<Angle> <Cardinal point>]] wrt <Name> where

  <Cardinal point> est E (east), W(west), N(north), S(south), U(up) or D(down)

  <Angle> is a real value between 0 and 90.

  <Name> is the name of an existing element (/* or /-HR for example)

  [] indicates an optional part. The same axis may not be used several times.

  The direction is always shown with respect to the level. If the direction is locked, it. click Coordinates locked to unlock it. The end position is adjusted to suit the new direction and the existing length. To avoid changing the desired direction, click Coordinates unlocked to lock it.

• Click Pick surface or edge to define direction and follow the prompt Pick Face or Edge to select the direction in the graphical view. Select an object in the graphical view and slide the cursor to the desired face. The direction is perpendicular to the selected face. The end position is adjusted to suit the new direction and the existing length. To reverse the direction, click Reverse Direction. To avoid changing the desired direction, click Coordinates unlocked to lock it.

• Select the start position, then the end position using the Graphical Pick Start/End option in the drop-down list above the Position frames. The user is prompted to Pick Start (Snap) WP Snap:, Pick End (Snap) WP Snap: to select two positions in the graphical view. If the direction is locked, the end position is adjusted to suit the direction. Otherwise the direction is calculated between both positions. The length is always calculated between both positions.

• Select the start position using the Move Graphically drop-down list above the Position frames. Follow the prompt Pick Position:Pick Start (Snap) WP Snap:, and select a position in the graphical view. The end position is adjusted to suit the direction and current length.

• Click Flip start and end position to flip the start and end position. The start position takes the end position values. The end position takes the start position values. The length keeps the same value but the direction is reversed.

• Click Use end position for start to continue the floor from the previous values. The start position takes the end position values. The distance and direction keep the same values. The end position is calculated from the start position, length and direction values.

The default position is at the origin of the level with an eastward direction with respect to the level and a length of 5000 mm.

In the graphical view, the positions proposed are shown by an arrow between the start and end.

Note:

The positions can be modified if the connectivity is activated.

Section Rotation

Enter an angle in the Section Rotation field.

The angle can have the following forms:

By default the rotation of the section is zero.

Note:

Use the rotation to define a cross-fall. The faces around the floor stays vertical if the catalogue element is defined correctly.

miter

Three methods are available to select each miter:

• Enter a direction in the field. The direction is always shown with respect to the level. If the direction is locked, click End direction always perpendicular to unlock it.

• Click Pick surface or edge to define direction and follow the prompt Pick Face or Edge to select the direction in the graphical view. The direction is perpendicular to the face selected.

• Click End direction free to choose the perpendicular to the direction of floor. The miter is calculated automatically when the direction of the floor is modified.

By default, the miters are perpendicular to the direction of the floor.

Connectivity

Note:

Do not use connectivity for a sloping floor.

Apply

Click Apply to create the sloping floor. The Modify Floor Slab window replaces the Create Floor Slab window. Enter a valid name in the Name field to activate it.

To cancel the creation of the sloping floor, click Dismiss. If the user navigate to another element, the window closes automatically.
