# Model Areas

The building model unites all areas of a building and the Free Construction within a single model. Each component, for example the post of a wall, possesses all the capabilities of a Free Construction component. Being able to do everything with every component is a major advantage; however, one works effectively only when the inputs are tailored to the specific situation of the component. Why enter three-dimensional coordinates for a wall post when a post is always perpendicular to a wall and parallel to its exterior faces; it is sufficient to enter a longitudinal dimension in the wall. These specialized input options are consolidated within the model areas.

The following model areas are available in the current version:

**Floor plan**: For entering walls, windows and doors in the floor plan.

**Wall construction**: Bars and plates can be entered into the walls. The layer outlines of the walls can be adjusted.

**Ceiling panel**: Ceiling levels can be defined in different storeys, optionally by adopting a floor plan contour, and can be provided with specifications.

**Ceiling construction**: In ceiling panels, structural ceiling elements and ceiling claddings can be created and edited in detail.

**Roof layout**: Here a building outline can initially be generated, optionally by adopting a floor plan or by tabular or graphical input, and assigned roof attributes for automatic roof layout. Profile values and slope variations can be assigned to each contour line for this purpose.

Roof layout is passed on automatically in this process.

**Dormer**: In the 'Dormer' model area, dormers are laid out and the dormer supporting structure is entered. In addition, the main roof openings and dormer walls can be entered.

**Truss construction**: In the truss construction area, truss systems can be entered across vertical and, if applicable, also free planes. This model area is particularly suitable for beams, brackets, posts under arbitrary timbers and similar elements.

**Free Construction**: DICAM: Creation of new components or further editing of the components that were generated in the other model areas. Particularly flexible inputs are possible here.

Each building is reopened in the model area that was last edited for that building. If a new building is created, one is automatically directed to the Floor plan model area. We assume that the vast majority of buildings have at least one floor plan and that input begins with this.

You switch between model areas using the functions in the menu 'File Operations - Model Area'.
