1.Cat Face Tutorial
Follow along with the Cat Face Tutorial to create your own MasterCAM file.
2. Install Parallels and Windows (if necessary) and MasterCAM
You are entitled to a free copy of Windows 10, which you can access from RISD’s “on the hub” store.
To install Windows on an Apple computer, we recommend using Parallels. For now, we recommend you start with the free trial. The free trial is only good for 14 days. When you are ready to purchase, you can get it from “on the hub”.
MasterCAM Home Learning Edition 2017 will be available from Marilyn on a USB key. You can borrow the key to drag a copy to your computer, then return it to her.
3. Name Plate – due Monday 4/2 at 9am!
Create a name plate for your self, to be executed in 1/2″ thick MDF on the CNC router. We will supply the material and will cut all of the names in one go. Some requirements:
You will be required to submit a MasterCAM file and a Rhino file for this project. Use the Rhino file below as a template to fit your Name Plate within. Use the layers included in this file as follows:
Name your Rhino and MasterCAM Files with the following convention: Firstname_Lastname_NamePlate
Place these files in your personal folder and the shared folder called “Name Plate”
Get the Template Here. The template includes sample curves for the name and outer profile. Delete these curves – don’t include them in the file you post the google drive.
4. Plywood Stool Phase 1
Working from the CNC Plywood Stool project brief, begin developing your design for this project. The primary deliverable for this phase is a 1:3 scale model. If possible, use a material that approximates the scaled thickness. You are welcome to use the laser cutter for this project, but be aware that only certain materials can be cut with this machine. Work iteratively, on-screen with Rhino, and off-screen with sketches and study models. Save all of your process work.
Create a folder in the shared google drive with your name and place in that folder:
5. Drive Tidy-Up
Make sure your projects to date are properly organized in the google drive. Most projects require content is placed in both the shared drive and your personal folder. Look at back at the previous assignment to make sure your work is where it needs to be, following the specifications of the assignments. Failure to do so will affect grading.
1. Paper Model Round 2 (final)
Revise your Rhino model as needed and create a final paper model for this project. This model should be a well crafted, carefully proportioned likeness of your chosen object, demonstrating thoughtful decisions about what to include as part of the form, what to represent with graphics, and how to abstract compound curving surfaces into simple, developable surfaces. Keep in mind that you are expected to include some representation of the color, materials, and finish of the original object – this can be very literal or more abstract in the way you make this representation. For now, focus on creating the model, but we will ask you to create a slideshow summarizing your work and process. Be sure that you are working in an organized fashion in Rhino as we will review the files.
You may continue to revise and improve your work for the first two assignments.
1: Mustard Bottle Tutorial
Follow along with the tutorial that shows how to build a mustard bottle. Try as best as you can to copy the rendering shown in the tutorial page.
2: Paper Model, Phase 1
Working from the Paper Model project Brief:
Place the following content into a new google drive folder called “Firstname Lastname Paper Model Phase 1”, put this folder in your personal folder and the shared folder for this project. In this folder, put the following images
3. 3D Printing
If you haven’t already done so, submit one of your glasses for 3D printing. We are pushing back deadline for this part of the assignment.
4: Chair Study Revisions
Rebuild at least one of your chair models to more accurately capture the form and proportions of the physical examples. Think critically about the appearance of your model vs. what you see when looking at the chair. Use photographs as reference if necessary.
Re-render the chairs in a neutral setting, using only simple extrusions as the pedestals to create an unobtrusive environment for the rendering. The goal is to create a rendering that demonstrates competency creating near photo-realistic renderings of realistic looking image of a plausible photoshoot. Follow the specifications below:
You are also welcome and encouraged to continue revising your glasses, especially the renderings.
Build a model of a sharpened wood “golf” pencil. Sample pencils will be distributed for inspection and measurement. First and foremost this exercise is about form, but proportions and dimensions are important too. Don’t worry about materials you can build this as if it was all one single material / piece.
In order to 3D print a model of one of your glasses, you will need to export it as an .STL file.
To do so you can follow these steps from Rhino:
Here are some screen shots showing the settings described above:
This file is now ready for 3D Printing. The monitors in the 3D printing lab in Bank building can you help you with the next steps.
I know there was some difficulty getting the renderings of the glasses to look right. I did some research and it looks like the newer versions of Keyshot require a slightly different strategy to get the glass to look right. In my video I show making separate “bodies” for the glass and the liquid. This is done to avoid interference between the glass and the liquid where the surfaces are occupying the same space. The extra step is to separate (using explode or extractsrf) the top of the liquid – that would make contact with the air – from the liquid that would make contact with the glass. There are additional settings that need to be configured for each part. See a full explanation here:
Here’s a quick test rendering I did:
Another feature that is relatively new to Keyshot is a setting called “transparency distance”. This setting is found on both the liquid and glass(solid) material and if you are trying to render a colored liquid it will be important to understand. Essentially, transparency distance can be understood as a color that correlates to the thickness of a part. If the part thickness is equal to the transparency distance, the material will be the color assigned to the transparency distance attribute. As the thickness decreases, the color becomes lighter and less saturated, and as the thickness increases, the color becomes a darker and more saturated. You can see a nice overview of this here:
Some more detailed and technical discussion around this topic can be read in this forum post:
I forgot to put the chairs in the studio until tonight. Sorry about this!
There are now four chairs (not including Dan’s) that are in the Prov Wash studio for your reference. The homework asks for 3 chair models, you can pick which 3 to model, but one of them must be the chair with arms. The other 3 are similar enough that you should be able to manipulate the curves from one to take on the form of the others. Just make sure you keep the curves for each chair and organize them with layers. Please don’t damage these chairs any more than they already are.
We didn’t look at this in class, but the “History” functionality in Rhino could be very useful as you are work on building the three bentwood chairs. This functionality will link input and output geometry. In other words, it can connect a curve (input geometry) with a pipe (output geometry) so that if the input curve is manipulated, the resulting output surface will follow this change.

Part of the homework is to comment on someone else’s project. There are several ways to do this, but all start with opening the google doc you want to comment on (duh):
As reminder, you are supposed to comment on the person whose last name is after your’s alphabetically (this exercise is for your benefit, so no need to comment on my post – it’s not included in this list). The last person in the order should comment on the first person. Here is a list of the class’s last names:
