Buildings parameters

Buildings allows you to create buildings or other box like elements which are based on the ground such as containers.

Buildings read AutoCAD polylines, arcs, circles, ellipses and splines. Buildings consists of base, walls, and roof. The shape of the building is defined by a polyline.

The height of the building can be defined in two different ways:

  •  If the polyline of the building has Z value, the building walls are be modeled from this absolute height to the ground.
  •  Otherwise (Z=0) the height of the building is defined by two settings in the building parameters: floorheight and number of floors (nrfloors).

Roof is modeled based on the building polyline and roofline polyline(s). Separate layer is defined for the polylines of the roof. The shape of the roof is defined by polyline(s).

The height of the roof can be defined in two different ways:

  •  If the polyline(s) of the roof have Z value, the roof is modeled from that absolute height to the building walls. Thickness value adds relative height to the roof.
  •  Otherwise (Z=0) the height of the roof is defined by roofheight setting in the building parameters. Thickness value adds relative height to the roof.
  •  If automatic_rooflines=yes, Automatically generates roofline between mid-points of the neighboring edges of the longest edge (Applies only for 4-corner rectangular buildings)

The height and material of the base are defined in building parameters. Texturing of the walls and the base start from the first vertex.

Parameters

layer  - Layer where wall lines are.

materials  - Material of the wall. Material's width and height properties define how many floors and corner positions the wall texture image has. Texture is stretched so that corners are always fixed by this division. If you choose multiple materials they are randomly put on buildings but are dependent from the roof materials. For example the first material here will always be used with the first roof material.

description  - A descriptive text for the entry. If defined, will be shown instead of the long description.

info text  - Information text attached to items.

info URL  - URL link attached to items. The Explorer can launch a Web browser with the URL.

object data tables  - Autodesk Map object data tables that will be used for source of object information for the elements in the virtual model. The table list also matches wildcards.

rooflinelayer  - Layer where roof lines are.

baseheight  - Height of the base from the highest surface level. If set to 0 no base is modeled and the wall stretches underground.

eavesWidth  - Width of eaves measured from the wall.

  • ≥0 – when on the dwg is outer walls edges
  • <0 – when on the dwg is outer roof edges.

floorheight  - Height of one floor.

nrfloors  - Number of floors. If left empty the number of floors is guessed based on the building size.

roofheight  - Height of the rooflines that don't have absolute position defined.

texwidth  - Width of wall texture in system units.

roofmaterial  - Material of the roof.

basematerial  - Material of the base.

facade_materials  - List of materials for use in facades. Number after the material name defines the wall line polyline segment number on which the material is attached. Numbering starts from first vertex of polyline and is always counter-clockwise independent from polyline direction. With this feature it is possible to attach facade textures for each facade separately. Facades that don’t have texture defined here will use the normal building material. Users can also texturize building facades using right click menu tools when building wall polyline is selected. See chapter 3 for more info.

automatic_rooflines  - Yes/no. 

  • Yes=Automatically generates roofline between mid-points of the neighbouring edges of the longest edge (Applies only for 4-corner rectangular buildings).

group  - The name of the group of these items.

texture_autofit 

  • segment = the facade texture will be always scaled to the facade defined by polyline seg-ment and from base to roof.
  • polyline = the facade texture will be always scaled to the whole building length (around the building) and from base to roof.
