Defining construction elements as circles

You can define areas and obstacles as circles, polygons or rectangles. All other types of construction elements can be defined as rectangles only (Defining construction elements as rectangles), (Defining construction elements as polygons).

A circular construction element is inserted by default with a contour containing 48 points. You can use these points to enlarge or reduce the construction element, but you cannot change the circular shape. If you want to change the circular shape, insert another point into the contour. This way, the circle is turned into a polygon, so that you may move or delete any point in the contour.

You can drag the circle to the desired size in the Network editor or enter a numerical value for the radius.

Notes:   You can specify that you need not press the Ctrl key when adding network objects (Right-click behavior and action after creating an object). For some network objects there are windows in which the attributes of a network object can be defined and edited. There are lists for this, for all network objects. You can choose whether you want to open a window, a list or neither of the two for the definition of network objects in the Network Editor (Right-click behavior and action after creating an object).

Tips:   You can define areas and obstacles by importing CAD data from files in the file format *.dwg (Importing walkable areas and obstacles from AutoCAD). This way you can complete an existing pedestrian network or generate a new network. Alternatively, you can define construction elements in the Network Editor via the shortcut menu > Add New <Name Construction element type> when a network object type is selected in the network object sidebar.

Defining a construction element by dragging it with the mouse

1.  On the network object sidebar, click the desired network object type of the construction element Areas or Obstacles.

The button is highlighted. The variant of the network object type is displayed in parentheses and the button is shown.

2.  Click again Areas or Obstacles.

3.  Select Circle.

4.  Using the mouse pointer, point to the desired position of the construction element.

5.  Press the Ctrl key and right-click on the desired starting point of the construction element and keep the mouse button pressed.

A transparent window opens and displays the current radius and the default 48 points of the contour.

6.  Drag the mouse pointer in the desired direction.

7.  Once the construction element has reached the desired size, release the mouse button and the Ctrl key.

The <Name Construction element type> window opens. The construction element is shown in color in the Network Editor.

• Area: gray, contour: yellow with 48 points
• Obstacle: red, contour: yellow with 48 points

8.  Edit the attributes of the inserted construction element type:

• Attribute of areas (Attributes of areas)
• Attribute of obstacles (Attributes of obstacles)

The attributes are saved in the list of the construction element type. All construction elements are numbered in sequence by default, independent of the individual type of construction element.

9.  Confirm with OK.

Defining construction elements by entering a radius

Entering a value for the radius allows you to define the circle in precisely the desired or required size.

1.  On the network object sidebar, click the desired network object type of the construction element Areas or Obstacles.

The button is highlighted. The variant of the network object type is displayed in parentheses and the button is shown.

2.  Click again Areas or Obstacles.

3.  Select Circle.

4.  Using the mouse pointer, point to the desired position of the construction element.

5.  Press the Ctrl key and right-click on the desired starting point of the construction element and keep the mouse button pressed.

A transparent window opens and displays the current radius and the default 48 points of the contour. You can overwrite the value for the radius without clicking in the window:

6.  Keep the Ctrl key pressed and type in a numerical value.

7.  Release the mouse button and the Ctrl key.

The <Name Construction element type> window opens. The construction element is shown in color in the Network Editor.

• Area: gray, contour: yellow with 48 points
• Obstacle: red, contour: yellow with 48 points

8.  Edit the attributes of the inserted construction element type:

• Attribute of areas (Attributes of areas)
• Attribute of obstacles (Attributes of obstacles)

The attributes are saved in the list of the construction element type. All construction elements are numbered in sequence by default, independent of the individual type of construction element.

9.  Confirm with OK.
