In this exercise you are asked to make drawings that will be printed and folded. One will be printed with the vinyl cutter tool. The other will be printed to a black and white printer. The printed forms will be folded and reassembled. There are a number of steps for these exercises, and you will be asked to document the objects at various points in the process.
Objectives/Outcomes and Assessment Criteria
Students will acquire and demonstrate: 1.) technical competency in working with layouts, basic drawing tools, coordinate input, object snaps, 2.) sense of craft through precision and care in the presentation of the work, 3.) design aptitude in the ability to solve work through a series of phases in a process, diligence in documenting those phases, 4.) judgment in the choice of subjects. 5.) consideration of limitations and constraints in the problem solving process.
If you are interested in the fabrication of boxes, you can watch this video: How It's Made - Cardboard Boxes.
B.1. For the first part find a box. The box can be any size. We will reduce the size when we send the files to the vinyl cutter. As you can see from the image above, boxes come in all shapes. Some boxes require no glue to assemble, but have tabs that slip into slots. The box should be one piece of cardboard.
B.2. Photograph the box. Find a location where you have a neutral background and no objects or furniture in the image. Also, try to find a place with good light.
B.3. Flatten the box.
B.4. Scan the flattened box. If the box is too big to scan take a photograph. The photograph should be as flat as possible with a background that allows you to easily see the profile as shown in the image below.
B.5. Bring the box to class.
B.6. Upload the images to your Google Drive.
B.7. Create a copy of your titleblock. Save the file and name it with your name followed by Box. Gladys Shu would name her file GladysShu_Box.
B.8. Create two layers: Profile, and Fold. The layers can have any color.
B.9. In model space draw the outer profile of your box on the Profile layer. Include any holes that are inside the outer profile. Holes can be drawn on the Profile layer too.
B.10. Change the layer to the Fold layer. Draw lines that represent fold locations if you need them. In the image below the cyan lines are on the Profile layer. The pink lines are on the fold layer. Notice how the fold lines are short and do not stretch along the length of each fold. They are just there to let you know where to fold. The vinyl cutter will be used to cut out the box. The cutter will cut all lines. The short lines in the image below will also be cut so it is important that they are short.
B.11. In layout view (paper space) enter the viewport and zoom to the composition. Center and enlarge it to fill the viewport.
B.12. Print to pdf.
B.13. Save your drawing file.
B.15. When you are ready to print, we will format your drawing file so it can be sent to the vinyl cutter. We can do this together in class or you can prep the file for cutting yourself. One step will be saving the file as a dxf file as shown below. The vinyl cutter can cut from this type of file. The next part is to erase all content in the layout view. Lastly, we will need to make sure that none of your lines are joined as polylines. If there are polylines, they need to be exploded.
B.16. Close the file.
B.17. Upload the dwg file to your Google Drive. If you made a dxf file, upload that too.
B.18. Print your dxf file using the vinyl cutter. (I can help you with this in the lab.)
B.19. Remove the unused portions of your box. Fold the box. Make adjustments as necessary and repeat the three steps above.
B.21. Photograph or scan the flattened image with a contrasting background. Notice how Hanna's box stands out against a contrasting green background.
B.21. Use a straight edge to form the folds of your box.
B.22. Form the sheet into the box form.
B.23. Photograph your folded box with a neutral background.
B.24. Make sure the following files are uploaded to your Google Drive.
Image of the original box before it was flattened.
Image of the original box after it was flattened.
Dxf file (if you made one)
Image of your new box flattened.
Image of your new box folded.
B.25. Part 2. Choose a folded form from the book titled Folding Techniques for Designers: From Sheet to Form by Paul Jackson.
B.26. Create a new Autocad file. There is no need to create a titleblock for this exercise. Name the file with your name followed by FoldedForm.
B.27. In model space draw the flattened pattern. Keep in mind that green lines are valley folds, and the red lines are mountain folds. Since the paper will be printed with a black and white printer, you will need to make a distinction between those lines. You could create separate layers with different linetypes. You could create separate layers and assign colors 250-255 which are shades of gray. Cuts must be drawn with hidden lines. To load a linetype, click on the word Continuous for the layer. To add more linetypes to the file, click on Load.
Select the Hidden linetype, and Ok.
Select the new linetype from the list, and Ok.
Everything that you draw on the layer should appear with a hidden linetype.
B.28. Save the file.
B.29. Print the file to the black and white printer.
B.30. Cut out the printed sheet with an Exacto knife and a straight edge on a cutting mat. I have all of these if you need them.
B.31. Fold the sheet using the lines you have drawn.
B.32. Take a few photographs of your folded form with a neutral background. Name the images with your name folled by FoldedForm1, 2, 3, etc.
B.33. Upload the drawing file and the images of your folded form.
