  2. 2. The Basics of Layers <ul><li>Layers </li></ul><ul><ul><li>Created by user to organize drawn objects </li></ul></ul><ul><ul><li>User may make as many layers as desired </li></ul></ul><ul><ul><li>Layers have a color, set by the user, for identification </li></ul></ul><ul><ul><li>Layers have a specified Line type </li></ul></ul><ul><ul><li>Common layers to create are Doors, Windows, Walls, Grid </li></ul></ul>
  3. 3. The Basics of Layers <ul><li>To Create a Layer </li></ul><ul><ul><li>From the Layers toolbar select the Layer Properties Manger Dialogue icon </li></ul></ul>
  4. 4. The Basics of Layers <ul><li>To Create a Layer </li></ul><ul><ul><li>Select the New Button </li></ul></ul>
  5. 5. The Basics of Layers <ul><li>To Create a Layer </li></ul><ul><ul><li>A highlighted NEW layer will appear </li></ul></ul><ul><ul><li>The user then types in the new layer name </li></ul></ul>Once a new name is typed, Enter will allow the next layer to be created
  6. 6. The Basics of Layers <ul><li>To Create a Layer </li></ul><ul><ul><li>Now the layer’s properties can be set </li></ul></ul><ul><ul><li>The user can specify a layer’s color, linetype, state and other properties </li></ul></ul>
  7. 7. The Basics of Layers <ul><li>To Set Layer Colors </li></ul><ul><ul><li>Touch in the color box , next to the name of the color for a layer </li></ul></ul><ul><ul><li>Select a color from the index and select OK </li></ul></ul><ul><ul><li>Color helps a user determine what layer they are drawing on </li></ul></ul>
  8. 8. The Basics of Layers <ul><li>To Set Layer Linetype </li></ul><ul><ul><li>Touch the Linetype name </li></ul></ul><ul><ul><li>The default will be Continuous </li></ul></ul><ul><ul><li>A dialogue box will appear with all the Loaded linetypes </li></ul></ul><ul><ul><li>Select Load to add more to this box </li></ul></ul>
  9. 9. The Basics of Layers <ul><li>To Set Layer Linetype </li></ul><ul><ul><li>Scroll to find the linetype you need </li></ul></ul><ul><ul><li>Select it to highlight it and hit OK </li></ul></ul>Common linetypes for designers are continuous, dashed and center line
  10. 10. The Basics of Layers <ul><li>Line Type Scale </li></ul><ul><ul><li>Lines that composed of segments have a factor that controls spacing </li></ul></ul><ul><ul><li>To help see dashes we can magnify the line with a scale factor </li></ul></ul><ul><ul><li>Type in LTSCALE at the command prompt </li></ul></ul><ul><ul><li>Select Enter and a new value </li></ul></ul>Ltscale of 1 Ltscale of 12 Ltscale of 48
  11. 11. The Basics of Layers <ul><li>Controlling Layers </li></ul><ul><ul><li>Once layers are created they can be selected and manipulated from the Layers toolbar </li></ul></ul><ul><ul><li>The layer that is being drawn on is in the window </li></ul></ul><ul><ul><li>To change the layer use the arrow to the right and scroll to a new one </li></ul></ul>
  12. 12. The Basics of Layers <ul><li>Changing an Object’s Layer </li></ul><ul><ul><li>Touch any drawn object </li></ul></ul><ul><ul><li>Its current layer will appear in the Layers toolbar window </li></ul></ul><ul><ul><li>Select a new layer, it will appear in the window </li></ul></ul><ul><ul><li>Click inside the drawing area </li></ul></ul>
  13. 13. The Basics of Layers <ul><li>Turning a Layer On/Off </li></ul><ul><ul><li>To turn a layer off select the light bulb in the window </li></ul></ul><ul><ul><li>The light bulb turns gray and the layer no longer shows on the screen </li></ul></ul><ul><ul><li>Make sure the layer you are drawing on is always turned on </li></ul></ul>
