1.4 Overlay 2D Images

How to overlay 2D images

In this tutorial you learn how to upload, position, and project 2D images.

Summary

  • To upload a drawing, click Project Setup, and then Drawing Overlay
    • Alternatively, from the Quick Access menu, go to 2D Drawing Overlay, followed by Edit
    • Click to upload a drawing from file, or drag and drop the file
  • The drawing appears as a 3D object, which can then be scaled, positioned, and projected onto the map
  • To edit, double click the object or click the pencil icon on the drawing card
    • Use the movement handles to manually position the drawing - translate and rotate

Scale & Position Drawing

There are 4 methods to scale (and position) a drawing:

  1. Scale to Distance - use a known/visible dimension
    • click two points on the drawing and enter the distance between them
  2. 2-Point Positioning - scale and position, by aligning points of reference that appear on both the drawing and the map
    • click two points on the drawing, and then click the corresponding points on the map
  3. Snap to position using another drawing - scale and position, by aligning with an existing drawing
    • select the drawing to snap to from the drop-down menu
  4. Scale Icon - manually edit size
    • click 'Scale' from the movement menu, and click and drag the corners of the object

 

View

  • Drag the handle under Opacity, on the side sheet, to adjust the transparency of the drawing
  • Toggle Project on Terrain, to project the drawing on the terrain and cover the existing map tile image
    • Note: The drawing is projected at the set opacity value
  • Click the lock icon on the drawing card, to lock its' position and prevent accidental editing or movement
  • Hide and show -
    • Click the eye icon on the drawing card
    • Click the drawing name from the Quick Access menu, under 2D Drawing Overlay

Pro tip: Use two fixed points on the ground such as painted traffic lines or a corner of a parking lot to align the drawings instead of the top of buildings. Satellite images are typically not perfectly vertical and it might cause some offset between the base of a building and the roof.
