Adding an Overlay
An overlay is a picture that is "draped" over the terrain.
It can be used, for example, to add a scanned image of your client's house
blueprints for use as a drawing template.
To add an overlay:
1. If you have not
already done so, first import your picture using the Picture Import Wizard.
2. Select Add
3. Click to place the
overlay on the landscape.
4. Move and size the
overlay as needed for accurate size and placement. To do this accurately, change
the grid size to a known distance on the picture.
For example, when sizing the blueprint in the example shown below, you would set
the grid size to 10' because that dimension is shown in the blueprint. You can
also use the Dimension object, which is
especially useful for dimensions that run at an angle.
The following is an example of a simple house blueprint
(created in a CAD program) which has been added to the landscape design using
the Overlay object.
Here's the same design after the house has been added using
the Add House tool.
Before you can use an overlay you must first import it using the Picture Import Wizard.
Overlays appear in a realtime walkthrough by default. You can prevent
this by unchecking the Show in Realtime Walkthrough option. See Overlay Properties for details.
you are finished working with your overlay you can simply delete it. Or, if you
would rather keep it for a reference, you can temporarily hide it using the Show/Hide Objects command. You can also put
it into its own layer and hide the layer. See Using
Layers for details.
