STEP 3 Typically the sections of both sides of a drill are held together with Socket Head screws. Shown below are the positions of the 4 screws. I used a hexagon-inscribed to show the top of the screw head. Click on the polygon button and see if you can create this shape. You will set an approximate size.

Shown below are the dimensions required to finish off the last 2 remaining sections of the Drill_housing. I would save your work and create a new construction layer. The dimensions on the left

STEP 4 Once the Drill housing is complete, start working on the drill battery. At this point, create a new construction layer and a new layer called Drill Battery. Make sure your drawing the correct lines on the correct layer. I would advise drawing the battery AWAY from the drill housing and moving it over once it’s completed. Try and do this because I want to make sure you have practiced the MOVE command. Also in the second drawing I’d like you to practice the linear array command – to produce the 4 OBLONG shapes.

STEP 5 The last main piece in the puzzle is the drill chuck. Once again – I would save my work, create a new layer called Drill_Chuck, start with a new construction layer and start the chuck away from the main body and move it into place once its finished. The outside section of the chuck is easy e nough just watch out for the 10 Degree angles. The ‘Chuck Grips’ are a little more difficult. If I was you, I would draw the main horizontal grip and use the construction layer to determine the proper centre -points of the remaining grippers. Use the copy command to COPY the remaining 4 grips and then use the ROTATE command to rotate them 5 and 10 degrees as shown.

STEP 6 Shown below is the final drill. I want you to use the ENT241 template provided and place the drill and a couple of reference dimensions on the part. Before you do this you need to add the drill -bit. The drill bit comes from a library called 3D Content Central. In order to use this site – you will need to create a free account and install a program called viewport. Type ‘drill bit’ in search – I want you to download a 2D DWG file called Misumi-SD8. This is tricky - but see if you can do it. You might need to use the SCALE command to make the drill bit smaller and then move it into place. Use CTRL-C & CTRL-V. Once all the parts are in their proper places – I want you to experiment with the different types of shading and stylizing to make your drawing look more realistic. The diff erent shading is created using the gradient function in HATCH. I used a yellow to orange gradient on the main drill body and a gray gradient for the drill battery shown below.

EXAMPLE 23 Here is an example of a structural steel beam connection. You need to find the dimensions for the I-Bream (W14x176) and the T-Beam (WT18x85). The dimensions are in this document. http://ola2.aacc.edu/tmcallinan/ENT242/steelsizes.mht The depth of this I-Beam is 25 inches and the length of the T- Beam is 21”. I need you to create your drawing as close a see it here with ortho, section & Iso views on the AACC template. Use the tool palette to obtain the 7/8 BOLT. Go to the mechanical section to find it i n the tool palette. The washer is not in the tool palette so use your own discretion here - use common sense dimensions. For some reason AutoCAD has bolts but no nuts so you’re going to find the nut block in the McMasterCarr website. You need to go to http://www.mcmaster.com/ and put McMasterCarr # 93827A271. McMasterCarr provides technical drawings for nearly every part it sells. In the left hand side, go to technical drawing and download the nut as a 2D DWG. You might need to scale the nut with the rest of the parts.
