2 General notes Allplan 2009

Basics Timber as a construction material is on the rise. It is used increasingly in the construction of apartments and houses.

In particular, new energetic requirements make this construction material so attractive to architects. Advantages of wood frame construction: short construction period, energy-saving design and low-cost construction thanks to prefab house design. The prefabricated units can be shipped to the building site easily and assembled quickly regardless of the weather.

In collaboration with Weto AG, Nemetschek Allplan has developed a solution that combines solid construction and timber construction. The timber construction module, which can be integrated in Allplan 2009, helps you design your projects with ecological considerations in mind. In addition, you can achieve maximum quality with the minimum of costs thanks to a consistent data flow - from design to production. The option to combine solid construction and timber construction in one application as well as numerous specific functions such as special solutions for corners, abutments, roofs and dormers considerably facilitate design of timber and wooden buildings of any kind.

Steps to success Basics 3

General notes The new Wall Production module (Timber construction family) enables architects and designers to reap the benefits of solid construction and timber construction combined in a single program. In addition to harnessing the advantages provided by this combined approach, you can immediately calculate costs and transfer data to machines - this saves you time and money.

• The most important features:

• Walls consisting of 3 layers (2 plates, 1 post)

- Functions for creating timber frame constructions (e.g. prefab houses)

- Posts: any setup, any material, any dimensions

- Freely definable plates (material, dimensions etc.)

- Any number of definitions for interior or exterior walls (up to 3 layers per wall)

• Predefined connection systems (can also be user-defined)

- Based on the wall setup defined, you can specify how the individual components intersect and interact (T-connections, corners etc.).

• Connection system

- Connections are created automatically after you have assigned definitions

• Modifying layer definitions of walls

- You can change the wall definition later and replace it with other types

• Headers or recesses for windows and doors are created automatically in the relevant wall layers

- You can define webs and headers for windows and doors in a dialog box

- After you have made all necessary definitions, the windows and doors are integrated automatically

- Window and door elements can be edited manually

4 General notes Allplan 2009

• Walls can be divided individually

- You need to select each wall separately in order to create posts and plates.

- You can delete the division of a wall by clicking a button. You can specify whether you want to delete individual layers of the wall or the entire wall.

• Edit tools (cutting; separating)

- You can use these tools to cut and intersect timber elements and to adjust them to auxiliary lines. Elements can be shortened and lengthened as you require.

- When separating components, you can cut out parts in their entirety: specify where you want to separate the component and the program will automatically delete the part in-between.

• You can make any entries in 2D and 3D (isometric view) as well as change materials and modify cross-sections

- You can change the materials and dimensions of all timber components later (you can even select multiple entries using the Shift key).

• You can copy, move and rotate objects using the familiar Allplan tools (e.g. timber schedule and quantities schedule)

- You can use Allplan schedules to analyze and evaluate timber elements

• You can use Allplan's layer structure to show and hide components and wall layers. Allplan provides a separate layer structure for timber construction.

• All walls adjust automatically to Allplan's roof planes. Flank walls are created automatically

- You can adjust individual walls manually to the roof frame

- You can edit window and door elements manually

Objective

Steps to success Step 2: transferring walls to wall production module 19

Transferring walls

To transfer the walls to the timber construction module

1 In the Tools palette, open the Wall Production module (Timber construction family).

2 Select the Transfer Walls tool.

Allplan transfers all the walls in the current drawing file to the Wall Production module. The walls are displayed in a separate dialog box. Now you can assign definitions and corner systems to the walls. In addition, you can make settings for door and window openings. As an additional option, you can cut the individual wall layers at the roof.

20 Objective Allplan 2009

Step 3: assigning wall types

After you have transferred the walls to the timber construction module, you will assign wall types to the walls.

Objective

Identifying the walls' outer edges Note: The manner in which the transferred walls are displayed in the timber construction module can vary considerably. This depends on how you create the walls. The illustration on the left shows the result when you enter the walls

Steps to success Step 3: assigning wall types 21

in a clockwise direction and the walls' offset direction is toward the inside (i.e. the arrow points inward). The walls are also entered in a clockwise direction in the example on the right; however, the arrow points outward.

You may get a completely different result when you transfer as-built data to the timber construction module. We assume that this is the situation in our example.

Before you can assign wall types to the walls, you need to check whether all arrows are aligned to the walls' outer edges.

To align the arrows to the walls' outer edges

1 Four walls are not oriented correctly in the example below.

Click these walls. They are displayed in red.

22 Identifying the walls' outer edges Allplan 2009

2 Click Turn.

The Turn function turns the selected walls around the center axis.

Now the arrows are aligned to the outer edges of the walls.

Steps to success Step 3: assigning wall types 23

Assigning wall types Next, you need to assign the corresponding wall type (exterior wall or interior wall) to each wall.

To assign wall types

1 In this example, you need to assign the following wall types:

To assign wall types, click the walls separately or select the relevant walls by enclosing them in a selection rectangle.

Start by selecting the three interior walls. They are displayed in red.

2 Click Set wall layer.

24 Assigning wall types Allplan 2009

Note: Always select walls first and then assign a wall type and not the other way round!

3 A dialog box opens. Select the Inner wall standard in the Available wall types area.
