About Walls
In ArchiCAD, you can draw walls that are straight, curved, trapezoidal and polygonal. They can be simple, of a single material, or composite, composed of several materials. You can even go a step further, and create complex walls (Profile Wall) of any custom shape and with a combination of materials.
Certain parametric objects such as Doors, Windows, and Wall Ends can only be placed into Walls.
Wall Reference Lines
Each Wall possesses a reference line and a direction. The reference line is a heavy black line (including the arrow that shows the Wall’s direction) that appears when you draw the Wall on the Floor Plan, provided that the View > On-Screen View Options > Show Walls & Beams Reference Lines feature is switched on.
The reference line helps you achieve the precise connection of Walls for clean intersections. It also establishes hotspots and edges for selecting, moving and transforming Walls.
The reference line is also relevant for determining which side of the wall is which, for assigning materials to the 3D model (in the Model panel of Wall Tool Settings).
See Wall Model Panel.
Depending on the chosen Construction and Geometry Method, the wall body protrudes on either or both sides of the reference line. The direction of the wall is defined by the order in which you define the wall’s endpoints.
Note: With the commands of the Modify Wall Add-On, you can modify the thickness, the Reference Line position and the direction of selected wall type elements.
See Modify Wall Geometry (Add-On) .
Display of Walls
Use the panels of the Wall Tool Settings dialog box to choose attributes for the display of your wall in the various 2D and 3D windows.
Attributes for each part of the representation (e.g. cut surfaces, overhead lines) are set using the pop-up options in the Floor Plan & Section panel of the Settings dialog box.
Use the Floor Plan Cut Plane Settings, combined with element projection preferences, to determine which parts of the placed wall should be displayed.
For more information, see Floor Plan Cut Plane (Global Setting) and How to Display Individual Elements on the Floor Plan .
Some aspects of Wall display depend on the current settings in View > On-Screen View Options.
Wall & Beam Intersections can be set on and off.
Other display options for Fill patterns are set in Document > Set Model View > Model View Options: you can opt to show contours only, or empty fills, or to display each element’s fills as defined in its own settings dialog box. In the case of composite walls, you can choose to display only the separator lines, or only a solid fill with no lines.
For more information, see Model View Options.
    
When you are satisfied with the choices you made in the Wall Tool Settings dialog box, you can start drawing Walls, in either the Floor Plan or the 3D Window.
