Drawing a Polyline

You can draw polylines and polygons in your experience. These drawings can then be used later on as areas of interest.

This task shows you how to:

Before you begin:
  • Drawings are created in the current experience context, no entity is created. Therefore, they cannot be search for or shared. Besides, they have no associated GIS attributes.
  • Multi-selection is not supported.

Draw a Polyline From Scratch

You can draw a polyline in your experience.

  1. From the Create section of the action bar, click Create Polyline .
    The cursor shape changes to .
  2. Click a start point, and then click successively to create line segments.
    A new polyline dataset is added in the tree view under the Created Items node and the polyline is drawn on your experience.

    The cursor shape changes to .

    Important:
    • Point handles (vertices) are placed in a XYZ coordinate space based on the picking manipulator location (that is, the intersection with the closest item to the camera under the mouse cursor). This means that you cannot click a point in the sky, but only on the ground or on one of the loaded items.
    • The location of point handles is determined at the time the point is created or moved. Therefore, points located on items with various levels of details (such as the ground mesh) are not updated when zooming in or out. They keep their initial location in space.
  3. To remove a segment from the polyline, double-click its handle.


  4. Optional: Click the last point to close the polyline.
    A red point handle is displayed to indicate that the polyline is closed, this handle cannot be manipulated.

    If you click anywhere on a segment, a new point handle is displayed which creates a new segment and lets you giive a new shape to the polyline.

    If you click another point handle, the red handle is displayed next to the clicked handle. Double-clicking the red handle removes the segment which lets you open the polyline.

  5. To stop drawing, click Create Polyline (or any other command in the action bar).


Draw a Polyline From a Cloned Item

You can use an existing loaded geometry to create polylines. This geometry can be either a prepared dataset or a dataset in preview.

  1. Click a geometry in the 3D view.


  2. From the View section of the action bar, click Properties .
  3. Click .
    The selected geometry is cloned and the cloned item is displayed under the Created Item node in the tree view.
    Important: After the cloning, the source object and the cloned one can be modified independently from each other.

Edit a Polyline

You can modify the shape of polylines, whether created from scratch, or from an existing loaded geometry.

  1. From the Create area of the action bar, click Edit Mode .

    If Edit Mode is deactivated, you can still select objects but not edit their shape anymore. You can only edit the representation attributes available in the Properties panel.

    This mode is not available if you have a read-only access to the dashboard.

  2. Click a polyline in the tree view or in the experience to display handles.

  3. Drag white point handles to modify the shape of the geometry, or click a point to display the vertical handle and then drag it to change the point altitude.
    Cloned polyline - Drag white handle

    Polyline created from scratch - Drag vertical handle

  4. From the View section of the action bar, click Properties , and then modify the properties according to your needs.
