Wall

	Geometric Primitives

The wall object defines a sequence of building walls. The object generates visible geometry only when placed into the 'wall definitions' sub folder of building object. The wall object needs one parameter object, a NURBS polyline. Currently smoothly bending NURBS curves define the wall by the control polygon.

Wall objects

The sub wall object has the following options available in the Property window's Spec tab:

Wall Geometry options:

Thickness: Thickness is wall specific. Outer walls are usually thicker than inner walls.
Side: defines to which side of the parameter polyline the geometry is built.
Snap Start, Snap End: If set, the respective end of an open wall segment is expaned to match the closest other wall. Room and buidling dimensions can be edited easily, because it is not necessary to adjust every wall dimension separately.
Virtual: virtual walls divide space but do not generate visible wall geometry. They are considered in wall snapping and in room divisions. For example, it is possible to divide the floor of a room into two separate areas, which have different materials, by splitting the space with a virtual wall. Wirtual walls also provide a way to cut staircase holes through ceilings and floors in buildings, which have several floors.

Roof Fitting options:

Extend to Roof: when enabled, the wall height is adjusted automatically so that the wall joins with the roof seamlessly. Outer walls often need this option, whereas inner walls stop at the ceiling.
Wall-Roof Penetration: A tolerance factor, which helps to close the gap between extended walls and the roof.

Walls extended to fit a curved roof

Fitting Interval: The wall height is matched with the roof at every corner and where a roof line crosses the wall. If the roof has a complex or even a smoothly bending shape, a low fitting interval may be necessary. This option defines a maximal distance between two fitting positions.
