FAQ

Forests

Forests allows you to create forests or other areas which are filled with certain elements.

Forests read AutoCAD polylines, arcs, circles, ellipses and splines. Forests are closed areas that are filled randomly with single elements.

Parameters

layer  - Layer where forest border polylines are.

materials  - Materials for elements, probability (0-1) of the element is separated with a semicolon ";" after the material name. This way amount of different elements can be defined accurately.

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.

objects  - List of the AutoCAD 3D blocks that will be used as elements in the virtual model the same way as texture elements. If more than one block is selected, one of them will be randomly chosen for each instance. Insertion point is always interpolated to the ground. Material information is read from the AutoCAD block (mesh) triangle materials. Texturing mode is always “Box”.

randomness  - Randomness in percentage of the size change.

density  - Number of elements in a hectare.

width  - Element default width, if empty material texture width is used.

height  - Element default height, if empty material texture height is used.

interpolation_mode

  • top - height = object Z – ground Z
  • bottom - height = height (default value).

interpolate_to_materials  - In case of multiple materials on top of each other, defines the material that these items will be interpolated on.

group  - The name of the group of these items.

buffer  - Expand the forest areas outwards (positive value) or shrink inwards (negative value).
