This is the 1st of the 3 view drawings, students will work form a worksheet with an Oblique
drawing that will need to be drawn in the 3-view format. To construct this 3-view drawing you will
need to know how to read the given dimensions on the oblique drawing. This will be used to
center the drawing. The height of the front view (2") will be added to the spacing distance (1") and
this will be added to thickness of the top view (2"). This total will then be divided in half to center
the 3 views top to bottom. The next step is to center the drawing left to right.

Pressure Plate #1
DISC/RING
_____/50pts.
This is the first of the Solid Works Drawing tutorials. Students will learn how to open the program,
Creating a "New Solid Works Document". The 1st. shape they will draw is a "Circle" and you will
learn to use the "Smart Dimension" tool to give it a required diameter. This circle will now be
extruded to a thickness of 7mm. Next, you will add two concentric circles and then raise them up
12mm to create a raised ring on the circular plate. Next you will learn how to draw, Dimension,
and cut a hole into the center of the plate. Students will now learn how to place "Text" on to their
drawing with their Name, Date, Title, Period, and Score.

In this Exercise you will learn how to "Create Holes Using the Hole Wizard". Using this you will
layout two counter sink holes for a "Flat Head - ANSI B18.6.7M machine screw". You will design
this and print it for a grade, and then you will delete the counter sinks, and save with a new file
name.
Pressure Plate #3 FILLETS/CYLINDER
_____/50pts.
In this drawing you will first add "Fillets" to several edges of the plate. Next you will perform the

Measurement Challenge #1
In MECHANICAL DRAWING ONE as you now know we expected that you should be able to
measure correctly with a 1/4” and 1/8” scale. This challenge will help you to develop your
measurement skills by having you work with the scale (ruler). As you follow the directions and
plot the letter points you will be constructing a picture (Sail Boat) with lines that connect the
points. I hope you enjoy this challenge! These will help you better layout your upcoming drawings.
Measurement Challenge #2
In MECHANICAL DRAWING ONE as you now know we expected that you should be able to
measure correctly with a 1/8” and 1/16” scale. This challenge will help you to develop your
measurement skills by having you work with the 1/16” scale (ruler). As you follow the directions
