Roof covering, parameters

Above all roof planes and dormer planes
(can be entered in a single operation; dormers with a roof overhang cannot be defined)

Fully bounded roof planes, such as dormers, are not taken into account
(dormers are cut out)

Only above fully bounded roof planes, such as dormers
(dormers must be fully bounded by roof;
dormers with a roof overhang can be defined)

Examples of entry types

(1) Above roof and dormer planes
(2) Fully bounded roof planes (dormers, for example) are ignored
(3) Above fully bounded roof planes only (e.g. dormers)

Enter the distance between the bottom of the roof covering and the reference plane (positive value = above; negative value = below).
Select the Relative height button to open a dialog box, where you can link the roof covering to a plane in the current plane model or current drawing file. By clicking

Match parameters (in the lower border of the Relative height dialog box), you can also use the height definition of another component for the roof covering. You can use the Offset box to enter the distance between the bottom of the roof covering and the reference plane (positive value = above; negative value = below). This is the offset that appears in the Roof Covering dialog box.

Specify whether the entries you make for the roof covering in plan apply to the Top level or Bottom level of the roof covering.

You usually know the bottom level of the roof covering (for example, top level of rafters). Taking eaves flashing, angle and thickness of the roof covering into account, Allplan automatically calculates the projected position of the top level.

When you select Bottom level, the position in plan can differ from the position defined by the points clicked.

When you enable the check boxes of the individual parameters/attributes in the All layers same settings line, all layers assume the setting you have made for the first layer. Any changes you make apply to all the layers, regardless of the layer which you are about to enter or modify.

Right-clicking a title line opens a shortcut menu which you can use to hide properties you do not need.

Right-clicking within a column opens a shortcut menu for editing the construction layers.

You have the following options:

Reverse setup of construction layers
Insert new construction layer before the line selected
Insert new construction layer after the line selected
Remove selected line

Enter the thickness of the layer or select a value in the dialog box.

To enter a new thickness in the library, click and then enter a value.

To remove an entry, select the entry and then click .

To change an existing entry, select it and click . Entries you change in this manner are not saved and not added to the selection.

The building trade assigned here is used later by the system to generate lists, schedules and analyze the building data.

To assign a building trade, click on an entry.

The priority influences the intersection of components of different component groups within a drawing file. A wall with a priority rating of 200, for example, will run straight through a wall with a priority rating of 100 as its rating is higher.

One instance of element interaction is walls which cross each other’s path. A ‘hole’ is created in the first wall. The hole extends along the entire height of the wall. This is called element interaction. You can determine which wall has a section (hole) removed from it by defining a different priority rating for each wall. Walls with a higher priority rating have precedence over walls with a lower priority rating.
Within a drawing file, this intersection also occurs for components of different component groups.

You can also change the priority afterwards in the Properties palette: This has the advantage that the intersection of the component with all intersected elements is immediately recalculated without having to perform restore 3D view.

The computation mode has a bearing on subsequent lists and schedules.

You might, for instance, list elements differently depending on the computation mode set here i.e., show the area of walls more than 4’’ thick and show the volume of walls more than 10’’ thick.

To specify a computation mode, select one of the modes (volume, area, linear) listed in the dialog box.

You can use the following tools to rearrange the layers and to copy the properties of individual layers. You can also find these tools on the shortcut menu of the columns:

You can define the Format properties of the roof covering or of each layer (if the roof covering consists of multiple construction layers).

Note: The properties in the Properties palette have no effect on the roof covering; the settings you make here apply.

This is where you can assign a layer to the architectural element or, in the case of elements with multiple construction layers, you can assign a separate layer to each construction layer.
The Select Layer/Visibility tab of the Layer dialog box opens so that you can select a layer.

Note: Basic layer settings such as Layer’s format properties and From layer, line style are taken into account and displayed in the dialog box. The settings made are represented by the relevant layer symbol. Consequently, you cannot make entries.

You can assign custom surfaces to the roof covering or, in the case of roof covering consisting of multiple construction layers, to each layer. You can also modify surfaces you have already assigned. These surfaces are visible in viewports of the Animation view type.

To assign a hatching style, click the box next to Hatching and assign a style.
If a background color is to be applied to the hatching, click the box next to Fill and select a color.

To disable hatching, deactivate the Hatching check box.

To assign a pattern, click the box next to Pattern and select a style.
If a background color is to be applied to the pattern, click the box next to Fill and select a color.

To disable the pattern, disable the check box next to Pattern.

To assign a fill, click the box next to Fill and select a color.
In addition to a fill, you can also select a hatching style or pattern; the pattern is then used for thebackground color.

To disable the fill, deactivate the Fill check box.

To assign a bitmap area, click the box beside Bitmap area and select a file.

To disable the bitmap area, deactivate the Bitmap area check box.

To assign an area style, click the box beside Area style and select a style.

Area styles must already be defined.

To disable the area style, deactivate the Area style check box.

Note: You can display the structure of the roof covering in architectural sections. To define the necessary settings, select the

Hidden-Line Image, Wireframe tool, click Hidden-Line Image and open the Formats palette.

The Total tab consists of the Parameters, Attributes, Format properties and Surface elements tabs.
