Seawall blocks drawing
4
To draw the front elevation

• Format Layer Layer properties manager
• Prepare layers for center, hidden and dimension
  lines use appropriate linetypes and ltscale

5
To draw the front elevation

• Draw 2700 by 1350 rectangle
• OFFSET to inside by 40 (all chamfers 40mm)
• (Modify Offset)
• Connect corners with lines

6
To draw the front elevation

• EXPLODE and OFFSET the left edge by 100 for the
  hole
• (Modify Explode)

7
To draw the front elevation

• Put it on the hidden line layer
• Set the linetype and linetype scale as follows
• Format Linetype Global scale factor
• LTSCALE (short cut lts)

8
To draw the front elevation

• To draw the (left) center line
• try LINE (use FROM snap mode by ShiftRight
  click)
• From Basepoint (pick top left corner)
• ltOffsetgt _at_ 800,0
• Specify next point _at_ -300,-1350

9
To draw the front elevation

• Put it on the center line layer
• SCALE the center line by 1.2
• (Modify Scale)

10
To draw the front elevation

• MIRROR everything on the left to the right

11
To draw the side elevation

• Turn on both OSNAP and OTRACK for object tracking
• RECTANG
• Without clicking, touch the top right corner and
  move mouse to the right (dashed line appears see
  below)
• Enter 1000 (or other suitable separation)
• Specify other corner point _at_ 2025, -1350

12
To draw the side elevation

• Modify - CHAMFER
• specify both chamfer distances as 40
• enter P (polyline option) pick the rectangle
  in side view
• CHAMFER similar to FILLET but bevels the edges
  rather than round them

Before Printing Use a suitable linetype scale

1. Check your original drawing limits using the
   LIMITS command they are from (0,0) to (a,b)
   (e.g. a 12, b 9)
2. Check the dimensions (AxB) of your paper, in mm
   (e.g. 297x210 for A4 or 420x297 for A3 paper)
3. What scale is to be used, 1S (e.g. S 50 for
   1 50 scale)
4. Approximately, the linetype scale should be
   (A/a)xS (e.g. 297/12x50). This is set in Format
   Linetype Scale (for the Global Scale Factor)

15
Before PrintingUse appropriate lineweights

1. Choose File Plot Style Manager (the following
   table appears)

16
Before PrintingUse appropriate lineweights

1. Double click acad.ctb (a file which stores the
   lineweight information by color) - click Form
   View tab and the menu appears

17
Before PrintingUse appropriate lineweights

1. Select the color that you used for each line type
   when creating the drawing. e.g. you may have
   used red (color 1) for all center lines purple
   (color 6) for hidden lines, blue (color 5) for
   steel bars, black (color 7) for solid lines
   (title block and concrete outline, etc.).
2. Assign the appropriate lineweight for each color
   (e.g. 1mm for blue, 0.5 mm for black, etc.)
   Save Close.

18
Set up the plot details

• File Page Setup Manager (the Page Setup
  Manager menu appears)

19
Set up the plot details

• Select Model and click Modify, then the
  following menu appears

20
Set up the plot details

• For Plot style table, choose acad.ctb Yes to
  use the lineweightes you assigned
• Choose Printer/plotter (e.g. BarnCL5) and Paper
  size (usually A3)
• In Plot Area, choose what to plot (e.g. by window
  choose corners of title block)
• Plot scale
• Check Fit to paper if scale is unimportant
  (e.g. just a rough draft)
• If a scale is specified, then uncheck Fit to
  paper
• Suppose scale is 150 (meaning 1 mm on paper
  will represent 50 mm of actual object), while
  drawing dimensions are in mm.
• Choose 150 directly or choose Custom and set
  1 mm (on paper) 50 units (on drawing)
• In Plot offset, select Center the plot
• Always Preview change the orientation to
  Portrait or Landscape if needed (right-click -
  Exit to exit preview). Click OK Close if
  all is OK.
