Happy Halloween everyone. In this tutorial, I’ll show you how to create a Minecraft-inspired jack-o-tangle using AutoCAD AutoDesk. I used the current 2014 edition for this project, but almost any edition should be able to achieve the instructions used (at least 2004 and above). Some prior knowledge of AutoCAD will be required to execute commands and understand how to rotate objects and displays, but the commands themselves, and the logic behind them, will be listed.
Attached is a .dwg file.
The first step is to find a picture of a jack-o-lantern for reference. I found the drawing paper overview to be most useful because it can tell you what the sides and top/bottom look like next to each other, and tell you the dimensions of the features based on the color bits. After you have the reference image, create a box that is 16 units by 16 units (any dimension, remember that the goal is to print 3D when done) using the line commands and the grid and snap buttons (set the grid / snap to 1/16 of the length/width your box to make the next section easy). Once you have the box created, use the command line and your reference picture to draw a face.
Next, either entering “region” in the command bar at the bottom, or turning on dynamic input, use the region command to highlight the entire face you’ve drawn. If your display type is in a 3D -based display, it will look like everything is now a solid plane, but it’s not. The parts of your face that have been completely covered, are now planes that can be used to make extrudable faces for your jack-o-lanterns.
After creating these four solid planes, we need to make it easy to use the face. Using the subtract command, first select the area you want to have the part subtracted from (outer box), right-click / enter, select the part you want to subtract out (eyes and mouth), and press enter/right-click.
The last step in creating a face is to give it depth. To look good, you should use the dimensions you set earlier for the distance of your grid buttons and snap buttons (because minecraft is based on cubic cubes after all).
Now that we have a face, we need another. There are several ways to do this step, so I will be a bit vague and make your decision easier.
1) One way is to outline the cube that will be your lantern, then create a box (using the box command) and rotate / mirror/move (all commands can be entered in the command/dynamics input window, or found in the “change” tab adjust “) box to the correct place. You will then stack the separate boxes together to create a cohesive unit.
2) The alternative route is to go back to step 2 instead of reducing the eyes and mouth from the faceplate, make a box with 16 * 16 * 16 dimension units and place the box in the middle which has dimensions of 14 * 14 * 14 units. You can then release the eyes and mouth, center them in the “face” of your box, and push them out.
Either way will take a long time, but one way may be easier or easier to understand. In the end, the goal is to achieve the perfect box that has two eyes and a mouth on one face: P.
At this point, we have a nice box with a face on it. The next few steps can be considered options if you just want a simple minecraft jack-o-lantern, though I recommend skipping to steps # and # to see about making a removable top or putting a hole in the bottom for a candle LED.
For a more decorated version though, use your original template and draw the sides and top as you did for the face. However, on behalf, you need to do two things differently: 1) You need to make two copies of each part and remove the first more than 1 unit out 2) the other copy should be extruded to 1/4 unit. The first copy will be used to make a groove next to the finished box only, and the other will be the part of the dye set in the groove that copies it.
Step 7: Option 1: handle
Personally, I like mine without a dick (maybe because I don’t like the look I’m drawing, but we’ll leave it for another time: P). If you’re a stupid type guy or someone else, don’t worry, I’ve considered you. Since I’m not happy with me, I can say that you want to make a box that is 1 * 1 * 1 unit and start copying and pasting until you have something you like. My fare is definitely used for reference.
Step 8: Option 2: Light It Up
This very named jack-o-tangle intends to get involved, so for this step, we need to add a hole in the bottom for the LED candles (these things will be made of plastic when you are done, so based on the candle flame would be a very bad idea ). This step will be very simple and only requires a hole to be cut from the bottom of the pumpkin. You need to make a hole about 1-2.5 inches in diameter because that’s the most standard size of the LED candles.
Step 9: Option 3: Crack It Open
Finally, the top is removable. This should be easy, as it only uses two commands. The first, is to create a box that has the dimensions of your outer box and a depth of one unit. After that, use the chamfer command to create the sloping edges, using unit lengths for both chamfer lengths. Once you have the top, make a copy, push it away from the top of the jack-o-lanterns, and you’re done.
