Buildings are sub documents of Cities and can be used to represent manufactured structures like houses, stores, warehouses, etc. They are defined by a curve. The aspect of a Building is defined by the Geometries applied to it. The roof can be represented by 3D models or by textures.

The Building view

The building view is separated in three parts:

The curve points list :

This part contains a list of all the curve points of the building. These curve points can be individually customized using the check boxes on each line. These modifications are applied on the next segment after the modified curve point. For example, if the "Blind wall" checkbox is checked on the point 0, the modification will be applied on the curve between point 0 and point 1.

Example of a Blind wall :

The parameters :

Each Building view contains a set of parameters used to change general settings on the building.

Building setup

The Building panels can be used to apply Geometries to specific modules of the Buildings. There are two panels for the Building document, the Roof panel, and the Facade panel.

Roof setup :

In the Roof panel, the user can set either textures or models for the roof. There are also a set of parameters to customize the roof.


It is possible to change the UV scale for each of the Materials.

Facade setup :

The facade panel allows the user to set up the modules of the Building with Geometries that will be displayed on the facade. Multiple Geometries can be applied on a single module. If several Geometries are set in a module, when displaying the Building out of draft mode, NDunes will pick one Geometries in the module to be displayed. The selection is randomised for every iteration of a module.
