3. 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
Details of the icon
- refer to textbook

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 Shift+Right click) –
From Basepoint: (pick top left corner)
800,0
Specify next -300,-1350
Shift + Right Click

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 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 **

14. Before Printing Use a suitable linetype scale
Check your original drawing limits using the LIMITS command: they are from (0,0) to (a,b) (e.g. a = 12, b = 9)
Check the dimensions (AxB) of your paper, in mm (e.g. 297x210 for A4 or 420x297 for A3 paper)
What scale is to be used, 1:S (e.g. S = 50 for 1: 50 scale)
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 Printing Use appropriate lineweights
Choose File – Plot Style Manager (the following table appears)

16. Before Printing Use appropriate lineweights
Double click “acad.ctb” (a file which stores the lineweight information by color) - click “Form View” tab and the menu appears:

17. Before Printing Use appropriate lineweights
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.).
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 1:50 (meaning: 1 mm on paper will represent 50 mm of actual object), while drawing dimensions are in mm.
Choose “1:50” 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.
