The forests object allows you to create forests or other areas which are filled with certain elements.
The forests object reads AutoCAD polylines, arcs, circles, ellipses, and splines. Forests are closed areas that are filled randomly with single elements.
Layer where forest border polylines are.
Materials for elements. The probability (0-1) of the element is separated with a semicolon (;) after the material name. This way, the amount of different elements can be defined accurately.
A descriptive text for the entry. If defined, it will be shown instead of the long description.
• info text
Information text attached to items.
• info URL
URL link attached to items. MAGNET Explorer can launch a web browser with the URL.
• object data tables
These are Autodesk Map object data tables that will be used for the source of object information for the elements in the virtual model. The table list also matches wildcards.
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. The insertion point is always interpolated to the ground. Material information is read from the AutoCAD block (mesh) triangle materials. The texturing mode is always “Box.”
Randomness in percentage of the size change.
Number of elements in a hectare.
Element default width. If this value is empty, the material texture width is used.
Element default height. If this value is empty, the material texture height is used.
This expands the forest areas outward (positive value) or shrinks them inward (negative value).
- top - height = object Z – ground Z
- bottom - height = height (default value)
In case of multiple materials on top of each other, this defines the material that these items will be interpolated on.
Select those layers that will be used to raise your component. For example, if you use LandXML as a reference or Civil 3D surface as a reference, you generate layers for those references and then select that layer into this box.
