The following options are provided for modifying walls:

• Reposition axis within wall
  When you enable this check box, all options for changing the geometric outline of the wall are locked; the thickness cannot be modified either. You can move the axis within the wall; the geometric position of the wall (absolute in the coordinate system) is retained.

  

• Recreate wall based on axis
  You can modify all the properties in the Wall dialog box (e.g. setup of construction layers, thickness values etc.). The position of the component axis is retained, and the wall is created along the axis with the new settings.

  

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 rating governs the way components of the same group behave when they intersect. A wall with a priority rating of 200, for instance, 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 setting a different priority rating for each wall. Walls with a higher priority rating have precedence over walls with a lower priority rating.
This interaction always occurs with elements of the same component group. But they do not interact with components belonging to a different group.

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.

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.

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.
