1. CIVL114 _________ LAB 3: Gauge Block

2. Outline Page Set-up Creating Layers, setting color & linetype Commands  Draw Lines  Round Corners Drawing the hidden & Center Lines Dimensioning

3. 1 Page Set-up Limits  Set up a boundary for drawing (not essential) Point  Draw a point at the right top corner

4. Limits  limits  “enter”  “enter”  420,297  ”enter” Point  Point  “enter”  420,297

5. 1 Page Set-up Zoom all (z – a)  zooms out to display the whole drawing Zoom extents (z – e)  To display everything that has been drawn (useful) Also try z – 0.7x, etc. Grid  Background points for visual reference Snap  Affects point selection but invisible

6. Zoom all (also try zoom extents)  z  ”enter”  a  ”enter” Grid  Grid  ”enter”  10  ”enter” Snap  Snap  ”enter  10  ”enter”

7. 2 Create Layers, Set colour & linetype New layers  Add two layers “ctrline” and “hdnline” Set color  give color to the layer Linetype  Change it to center line or hidden line

8. New layers  Click “format”  click “layer properties manager”  “new layer”  type “ ctrline”  “new layer”  type “hdnline” Set color  pick “white” (default)  select “red” and “green” respectively  ok Linetype  Pick “continuous” (default)  load  center line or hidden line  ok  select center line or hidden line  ok  ok

9. 3 Draw Lines Line

10. 132 546  L  “enter”  200,20  ”enter”  @50<90  “enter”  @50<180  “enter”  @26<90  “enter”  @50<180  “enter”  @76<270  “enter”  @100<0  “enter”

11. 4 Round Corners Fillet  To round a corner Circle

12. Fillet  Fillet  “enter”  R  “enter”  19  ”enter”  pick line A and line B  “enter” or fillet  pick line E and line F Circle  C  “enter”  cen   “enter”  pick lower left arc  9.5  “enter”

13. 5 Draw Lines in Side View Copy  CP or CO Line  L

14. Copy  CP  pick line A  “enter”  pick any point on the screen  @25<0  “enter”  Cp  L  “enter”  pick any point on the screen  @50<0  “enter” Line  L  end  pick the lower end of line I  end  pick the lower end of line H  “enter”

15. 5. Draw Lines in Side View OFFSET  Creates parallel copies of lines, circles, arcs, or polylines EXTEND  Extend a line to a boundary

16. EXTEND  pick the line J  “enter”  pick lines G and H  “enter OFFSET  Offset  “enter”  76  pick the line I  pick any point above I  “enter” OFFSET  Offset  “enter”  50  pick the line I  pick any point above I  “enter” Line I Line J Line H Line G

17. 6. Draw the hidden & center Lines Zoom windows  Z  “enter”  w  ”enter”  80,0  ”enter”  290,110  “enter” Hidden Lines  Pick layer “HDNLINE”

18. Line (you can switch on OSNAP and click points for QUA, PER, etc)  L  ”enter” .y  ”enter”  QUA  “enter”  pick the top part of circle  end  pick either end of line G  PER  pick the line H  “enter”  L  ”enter” .y  ”enter”  QUA  “enter”  pick the lower part of circle  end  pick either end of line G  PER  pick the line H  “enter”

19. 6. Draw the hidden & center lines (cont.) Center Line  Pick layer “CTRLINE”  L  ”enter” .y  ”enter”  CEN  “enter”  pick the circle  end  pick either end of line G  PER  pick the line H  “enter”

20. Center Line  L  “enter”  QUA  “enter”  pick the top part of circle  QUA  “enter”  pick the lower part of circle  L  “enter”  QUA  “enter”  pick the left part of circle  QUA  “enter”  pick the right part of circle

21. 6. Draw the hidden & center lines (cont.) Scale  SCALE (or click the SCALE icon)  “enter”  pick center lines in circle  INT (or use OSNAP)  pick intersection of the 2 center lines  1.5  “enter”  SCALE  “enter”  pick center lines inside view  MID  pick the 2 center lines  1.2  “enter”

22. 7. Dimensioning Dim (or use the menu)  Dim  “enter”  dimscale  “enter”  18  “enter”  hor  ”enter”  end  ”pick LHS of D”  end  ”pick RHS of D”  ”move mouse to suitable place & click left button”  “enter” Others: ver/ra/dia….etc (all available from dimension menu)

23. 8 Modify the dimension style Change the precision  Click “dimension”  click “dimension style manager”  click “modify”  click “primary units”  click “precision”  0
