Create Floor Grating Component

Referring to the hierarchy, a grating component element must reside below an existing grating element.

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

On the Building tab, in the Create group, by default Component is displayed in the Create Element drop-down list.

Click Create Element to display the Create Grating window.

By default in the Naming pane of the Create Grating 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.

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.

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.

The Grating Thickness can be populated in several ways:

• Enter the absolute finished level (wrt World) in the Top Level field.

• 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.

• Enter the finished thickness in the Thickness field. If the thickness is locked, click Padlock to unlock it.

• Click Measure Height the user is prompted to Height:Pick Start (Snap) Snap:, Height:Pick Start (Snap) Snap: and select two graphical picks.

• Enter the absolute bottom level (wrt World) in the Bottom Level field.

• 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 user does not want the thickness to adapt to level changes, click Padlock to lock the thickness.

• The default finished level is zero with respect to the level. The default grating thickness is 0.100 meter.

Click Catalogue to copy the default specification values from the Plates tab. Refer to Default Panel Specification for further information.

Click Pick profile to copy copies the properties of an existing grating.

The Position section of the window is used to establish the centre position of the grating. It can be populated several ways:

• Enter the values in the fields for East, North and Up in the Position frame. The reference can be changed by entering the name of an existing element in the Wrt field. If the field is greyed out, click Coordinates locked to unlock it.

• Select the position in the graphical view using Select Structural Element in the Position frame. To avoid changing a desired value in a field, click Coordinates unlocked to lock it.

The default position is at the origin of the level. By default, the position is the origin of the grating. For rectangular and circular shapes, the origin is at the center. To select a reference point to position the grating click the Reference drop-down list.

The Orientation section of the window is used to establish the Direction and Rotation angle of the grating.

The Direction textbox displays the direction of the grating (defined from the start to the end positions).

The direction may be changed using a number of methods. The direction can be re‑established by typing a new direction (for example: U, N, N45E, S30W15D) then click Enter.

Clicking Pick surface or edge to define direction allows the user to select an existing edge or surface in the model. Where a surface is selected then direction is set perpendicular to it. Where an edge is selected the direction is aligned with the edge.

Clicking Rotate angle using two picks allows the user to graphically pick the rotation angle by using the Positioning Control window. The user is prompted to Pick first point to define rotation (Snap) Snap:, Pick second point to define rotation (Snap) Snap: to pick two points in the graphical view. A graphical aid line displays the angle of rotation created by the picks. Alternatively the user can type in an angle using a format of degrees, minutes, and seconds.

The Shape of the grating element is also required. The option list in the Shape section of the window has three configurations; Rectangular, Circular, and Complex.

Dimensional information can be entered directly or using graphical picks. The content of the Shape section of the window, particularly the functionality of the graphical pick and dimensional textboxes, changes to suit the configuration selected.

Where complicated geometry is required the user can select the Complex configuration. The 2D Contour Editor window is displayed.

Click Apply to create the grating. The Modify Grating window replaces the Create Grating window.

To cancel the creation of the grating, click Dismiss. If the user navigates to another element, the Modify Grating window closes automatically.

Note:

It is also possible to create a grating with AVEVA E3D Design using the Plates application. On the Plates tab, in the Create group, click Panels.
