Beginning AutoCAD 2015. Cheryl R. Shrock

      2.Make layer Object “current” (I am having you do that because you can’t Freeze or Lock a layer that is current and I want to make sure that none of the layers that you used in the drawing is current.)

      3.Freeze the following layers: Window and Plants (Do not use erase)

      4.Lock layer Roof

      5.Try to erase any of the roof lines.

      You can’t because the Roof layer is Locked.

      6.Save the drawing as: EX3E

       EXERCISE 3F

       INSTRUCTIONS:

      1.Start a new file using template Acad (do not select Acad3D) (Located in the Template list 3 names below your 2015-Workbook Helper template)

      3.Create 3 layers named Fence, Gas and Invisible. (Refer to page 3-15) Assign the Name, Color, Linetype and Lineweight as shown above.

      4.Draw the LINES below using the new layers:

      A.Select the layer

      B.Select the Line command

      C.Draw the lines approximately 5 inches long.

      D.Ortho (F8) ON.

      5.Save the drawing as: EX3F

       EXERCISE 3G

      1.Open EX3B

      2.Open the Layer Properties Manager (Refer to page 3-10)

      3.Change Transparency of the Object Line layer to 70 (Refer to Page 3-14)

LESSON 4

      LEARNING OBJECTIVES

       After completing this lesson, you will be able to:

      1.Understand Object Snap

      2.Use Running Object Snap

      3.Use the Zoom options to view the drawing

      4.Change the Drawing Limits

      5.Select the Units of Measurement and Precision

OBJECT SNAP

      In Lesson 3 you learned about Increment Snap. Increment Snap enables the cursor to move in an incremental movement. So you could say your cursor is “snapping to increments” preset by you.

      Now you will learn about Object Snap. If Increment Snap snaps to increments, what do you think Object Snap snaps to? That’s right; “objects”. Object snap enables you to snap to “objects” in very specific and accurate locations on the objects. For example, the endpoint of a line or the center of a circle.

       How to select from the Object Snap Menu

      1.You must select a command, such as LINE, before you can select Object Snap.
