	Building Construction Tools

This is the main tool for building construction. Other building tools described below add sub components to the manager object created using this tool. To use the tool:

Take a top view and click the building tool button
Define some building options (see the option list below) if necessary
Click a sequence of points in a view window to define the outer wall for the building
In polyline mode, click Accept to finish an open wall sequence, or close the wall loop by clicking on top of the first point
Go to the material library of the select window. Using the property window, select some texture maps for the material templates, which the tool created.

The tool has the following options:

Type: rectangle or polyline. Rectangle mode switches automatically to polyline drawing if the two first points define a vertical or horizontal line (a collapsed rectangle would be useless). In polyline mode, the first line can travel in any angle.
Closing: Automatic mode draws an open line which closes automatically when the user clicks on top of the first point. Open mode keeps the line open and does not finish at overlapping points. Closed mode forces a closed wall loop, so that the tool can be finished by selecting Accept or by hitting enter key, and there is no need to aim at the first point to finish the tool.
Auto Texture: when set, the tool adds material templates for texturing the building parts (walls, base, floor and ceiling) to the material library. The tool also adds required material maps to the geometric hierarchy of the building.
Wall Thickness: can be defined here or changed later using the property window.

The defined wall point sequence can be found from the sub hierarchy of the building object. It is the first wall object in the 'wall definitions' sub folder. The actual point sequence is stored into a polygonal NURBS curve in the mentioned wall object hierarchy. Editing the NURBS curve updates the walls.

	Note
	Although the building tool accepts open wall sequences, real houses should include a closed outer wall loop in the first wall object. The same data defines directly the base and the roof edges. Splitting walls to several open sections disables automatic base and roof construction.
