What are Layers?

What are Layers? Layers are like transparent sheets, placed one on the top of another

There are three layers to every Draw file.
Point to the Layout Layer tab at the bottom.

Circle the Draw page once from top to bottom.

The Layout layer is displayed by default.

This is where we create most of our graphics.

Click on the Control Layer. The Control layer is used to store control elements such as buttons and forms.
Click on the Dimensions Layer. The Dimensions layer is used depict dimension lines or measurement lines for complex drawings.
Display the drawing of house on a slide and
point to the appropriate parts as per the narration
For example, a drawing of a house must contain exact measurements of walls, positions of electrical wiring and so on.
Point to the House and then the School Let’s print three maps that show the route from the House to the School.
Let’s call them Map 1, Map 2 and Map 3.

In Map 3, let’s show all the objects except the Park.
Do we need to create three separate maps to show these?

No, Draw provides a solution to this with the help of Layers.

This way, there can be only one map file with many layers of information.

Layers We can print or view a combination of layers using one Draw page.

This in turn makes updating information a simple process.


We can

  • print or view a combination of layers
  • using one Draw page.
Let us add some layers to the RouteMap.
Click on Layout Layer. Click on Layout layer.
Right click >> select Insert Layer Right click and select Insert layer.
Insert Layer dialog box appears. The Insert layer dialog box appears.
In the “Name” field type “Layer four”. In the “Name” field, type “Layer four”.

Check the boxes “Visible” and “Printable”. Check the boxes “Visible” and “Printable”.
Click OK to exit the dialog box. Click OK to exit the dialog box.
Click on Layout layer. Click on Layout layer once again.
Select the Route Map and ungroup it. On the Draw page, select the map and ungroup it.
Select the two lakes, the stadium and the commercial complex.

Use the Shift Key and the mouse to select these objects.

Now let us select the Lakes

Now press the Shift key and select the Stadium and the Commercial complex. <Pause>

Right-click and select Cut. Next right-click and select Cut.
Now click Layer four and paste them there. Then click on “Layer four” layer and paste them.
Point to them to show they are pasted in the same places. They are pasted in the same positions as in the Layout layer.

Create two routes from Home to the School Campus in the RouteMap drawing Create each route

  • on a separate layer
