11.6 Exercises


  1. Open topography .dwg (Figure 11.6.1a) from the C:\Steps\Lesson11 folder.

    click to expand
    Figure 11.6.1a:

    We shot several elevations during a survey of an area golf course. The elevations for Hole # 3 are shown.

    Using the SPLine command, draw contour lines connecting like elevations. This will afford you a topographical view of the area.

  2. Open Piping plan 11.dwg in the C:\Steps\Lesson11 folder. The drawing looks like Figure 11.6.2a.

    click to expand
    Figure 11.6.2a:

    2.1    

    On the Const layer, create horizontal constructions lines at these coordinates:
    0,18'; 0,28'; 0,48'; 0,39'6; 0,16'

     

    2.2    

    Create vertical constructions at these coordinates:
    12'6,0; 27'6,0; 42'6,0; 57'6,0; 50',0; 72'6,0

     

    2.3    

    Create a 45 ° angled construction line at 50',48'.

    Your drawing looks like Figure 11.6.2b (without the arrow):

    2.4    

    On the Equip layer, draw a 15' diameter circle at the intersection indicated by the arrow in Figure 11.6.2b.

     

    2.5    

    Using modification commands, position the ibeams, pipe supports and nozzle as indicated in Figure 11.6.2c.

    click to expand
    Figure 11.6.2c: Copy the Ibeams, Pipe Supports and Nozzle

     

    2.6    

    Add the matchlines as shown in Figure 11.6.2c (use 3"wide polylines on the Matchlin layer). Trim and change the layer of the construction lines to Center. Your drawing will look like Figure 11.6.2d.

    click to expand
    Figure 11.6.2d:

     

    2.7    

    Save the drawing as MyPipingPlan12 in the C:\Steps\Lesson12 folder.

  3. Start a new drawing from scratch. Save it as MyContPanel.dwg in the C:\Steps\Lesson11 folder.

    3.1    

    Accept the default limits, but set the grid to ½ and the snap to ¼. Create layers as needed during the drawing session, but begin with the basic const, object, text, centerline, and hidden layers with appropriate colors and linetypes .

     

    3.2    

    Using the grid as a guide, draw construction lines on the const layer, as shown in Figure 11.6.3a.

    click to expand
    Figure 11.6.3a:

     

    3.3    

    On the object layer, draw rectangles as shown in Figure 11.6.3b.

    click to expand
    Figure 11.6.3b: Rectangles with ½" Fillets

     

    3.4    

    Now draw the buttons as shown in Figure 11.6.3c. Use the grid to guide you as you draw the inner ellipses. Offset those 1/16" outward for the outer ellipses. Put the buttons on their own layer.

    click to expand
    Figure 11.6.3c: Buttons

     

    3.5    

    Now complete the drawing as shown in Figure 11.6.3d.

    click to expand
    Figure 11.6.3d:

  4. Start a new drawing from scratch as you did in Exercise 3. Save the drawing as MyHolder2.dwg in the C:\Steps\Lesson11 folder.

    4.1    

    On the const layer, create the construction lines shown in Figure 11.6.4a.

    click to expand
    Figure 11.6.4a: Construction Lines

     

    4.2    

    On the object layer, create the circles shown in Figure 11.6.4b. (The smaller circles are 3/8"dia. And the inner circle is offset 1/16 from one next to it.)

    click to expand
    Figure 11.6.4b: Circles

     

    4.3    

    Snapping to the points indicated in Figure 11.6.4c, draw a spline as shown.

    click to expand
    Figure 11.6.4c: Spline

     

    4.4    

    Draw the notches and add construction lines as indicated in Figure 11.6.4d.

    click to expand
    Figure 11.6.4d: Notches & Additional Construction Lines

     

    4.5    

    Complete the drawing (see Figure 11.6.4e).

    click to expand
    Figure 11.6.4e:

  5. Using what you've learned, create the drawings shown in Figures 11.6.5a to 11.6.5c. Don't draw the hatching.
