Note: Transparency selections will be saved within the current drawing and will not effect any other drawing.

       Plotting Transparent Objects

      Plotting transparency is disabled by default. To plot transparent objects, check the Plot transparency option in either the Plot dialog box or the Page Setup dialog box. This will be discussed in Lesson 26

CREATING NEW LAYERS

      Using layers is an important part of managing and controlling your drawing. It is better to have too many layers than too few. You should draw like objects on the same layer. For example, place all doors on the layer “door” or centerlines on the layer “centerline”.

      When you create a new layer you will assign a name, color, linetype, lineweight, transparency and whether or not it should plot.

      1.Select the Layer command using one of the following:

      Ribbon = Home tab / Layers panel / or Keyboard = LA <enter>

      2.Select the New Layer tool and a new layer will appear.

      3.Type the new layer name and press <enter>

      4.Select any of the features and a dialog box will appear.

       Features:

      Refer to the previous pages for controlling and selecting color, lineweights and transparency.

      Refer to the next page for Linetype.

       LOADING and SELECTING LAYER LINETYPES

      In an effort to conserve data within a drawing file, AutoCAD automatically loads only one linetype called “continuous”. If you would like to use other linetypes, such as “dashed” or “fenceline”, you must Load them into the drawing as follows:

EXERCISE 3A

       INSTRUCTIONS:

      1.Start a NEW file using 2015-Workbook Helper.dwt.

      2.Draw the LINES below using:

      A.Line command

      B.Ortho (F8) ON.

      C.Turn Increment Snap (F9) ON

      3.Select the appropriate layer, then select the Line command, then draw a line.

      4.Select the appropriate layer, then select the Line command, then draw a line.

      5.Select the appropriate layer, then select the Line command, then draw a line.

      Are you noticing a pattern here?

      6.Save the drawing as: EX3A

       EXERCISE 3B

       INSTRUCTIONS:

      1.Start a NEW file using 2015-Workbook Helper.dwt.

      2.Change the Increment Snap to .20 and Grid spacing to .40

      If you have the Snap and Grids set correctly it will be easy.

      3.Make sure SNAP and GRID status bar buttons are ON.

      4.Draw the objects below using layer Object Line. Review pages 3-2 through 3-6 for Circle and Rectangle options.

      5.Do not dimension, you will learn dimensioning soon.

      6.Save the drawing as: EX3B

       EXERCISE 3C

       INSTRUCTIONS:

      1.Start a NEW file using 2015-Workbook Helper.dwt.

      2.Draw the Rectangles below using the options:

      Dimension, Chamfer, Fillet, Width and Rotation

      3.Use layer Object Line.

      4.Save the drawing as: EX3C

       EXERCISE 3D

       INSTRUCTIONS:

      1.Start a NEW file using 2015-Workbook Helper.dwt.

      2.Important, important: Draw the objects below using the following Layers:

      Roof, Wall, Window, Door and Plants

      3.You can change Snap and Grid settings to whatever you like.

      4.You decide when to turn Ortho and Snap ON or OFF.

      5.All objects must be placed accurately. All lines must intersect exactly.

      6.Save the drawing as: EX3D
