The element areas object allows you to create areas filled with certain element masses, for example, humans, materials, etc.
The element areas object reads AutoCAD polylines, arcs, circles, ellipses, splines, or 3D faces. The defined area is filled with single elements based on the parameters.
Layer where the element area 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 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. Texturing mode is always “Box.”
Randomness in position in system units. Has effect only when randpattern is set to yes.
Randomness in size in percentage.
Distance of elements in X direction in drawing units.
Distance of elements in Y direction in drawing units.
Rotation of distribution pattern.
Angle = Rotates the resulting object’s z-axis. With this parameter, objects can be rotated so that they are not pointing upward. Setting this to 90 will result in objects that are horizontal.
If set to yes, the program uses its own random generator to place the trees. In this case, rotation parameter has no effect, and density is defined only with densityx as number of elements in a hectare. If set to no, elements are placed into a rectangular grid which you can affect with a rotation parameter. In this case, density is defined with both densityx and densityy parameters.
If set to yes, elements are always faced to the viewer.
Select yes or no.
Width of single elements. If left empty, the width of the material or the objects is used.
Height of single elements. If left empty, the height of the material or the objects is used.
If set to yes, polylines are used. This means that polylines of the concerned layer are used to generate element areas.
If set to yes, 3D faces are used. This means that 3D faces of the concerned layer are used to generate element areas.
If set to yes, this element area will remove elements inside the polylines/triangles instead of creating them. It will apply to the elements defined as materials (unless none is defined, then all elements inside the polylines/triangles are deleted).
Expands the element area outward (positive value) or shrinks it inward (negative value).
Creates a circular element area around each point on this layer. The radius of the area is defined by the buffer parameter. With this parameter, it is possible to use points as element areas. With a negative parameter, it is possible to remove elements around points.
Creates an element area around the polylines on this layer. The area size is defined by the buffer parameter. With this parameter, it is possible to use lines and non-closed polylines as element areas. With a negative parameter, it is possible to remove elements around polylines (like remove trees from road lines). If this value is set, all polylines are handled as non-closed polylines, and an area is created around the polyline and not as a normal polyline element area.
Material for an element's background. If this material does not have texture, the alpha channel of the front material is used.
The z value of the elements are taken from the z value of the polyline.
- top = The element stretches from the ground. The top of the element is set to the polyline elevation.
- bottom = The element height is read from the height parameter (default setting).
In case of multiple materials on top of each other, 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.
Shifts objects according to given transformation parameters (X,Y,Z).
- default = Objects are aligned vertically as usual.
- surface = Objects are aligned so that they follow the surface shape. Texture elements are aligned perpendicular against the surface triangle. 3D objects are aligned to the surface using object dimensions (bounding box) and lowest points.
