1. IOT POLY ENGINEERING 2-15 January 25, 2010 Pass in your Line Weight Practice Get out the following: –Timeline project handout –Orthographic Projection 1 Drawing PREPARATION Technical Graphic Communication

3. ½” 1. Draw ½” border 5/16” 2. Draw a 5/16” title block 3. Add 2 LIGHT lettering guidelines, 1/16” from border lines LETTER the title block information: BPI-IOT ORTHO PROJ 1 17 OCT 08 LAST, F FULL SCALE 4. Add scale separator – Heavy Weight 1 ¾”

4. 5. Measure the overall width and height of drawing space W H

5. 1. Add width of front view to width of right view. 1.5” 2. Add the space we will put between: 1.5” 4”1.5” 4” + 1.5” + 1.5” = 7” HORIZONTAL STARTING POINT

6. 3. The remaining space is equal to W – 7” = ~3”. 4. Divide the remaining space by 2 to get horizontal pt. Horizontal Starting Point is 1.5”

7. 1. Add height of front view to height of top view. 1.5” 2. Add the space we will put between: 1.5” 2.5” 1.5” 2.5” + 1.5” + 1.5” = 5.5” VERTICAL STARTING POINT

8. 3. The remaining space is equal to H – 5.5” = ~1.75”. 4. Divide the remaining space by 2 to get vertical pt. Vertical Starting Point is 7/8”

9. DRAWING ORTHOGRAPHIC PROJECTIONS 1.Draw border and title block 2.Locate starting point to center drawing (use construction) 3.Construct front view and PROJECT lines across paper 4.Construct top view and PROJECT lines across paper

10. DRAWING ORTHOGRAPHIC PROJECTIONS 1.Locate the top-most, right-most intersection of front view construction lines. 2.Use a 45-deg triangle and project a miter line. 3.Project lines down for right view. DARKEN what needs to be DARKENED DO NOT ERASE CONSTRUCTION LINES THEY FADE IN COMPARISON TO OBJECT LINES
