If you have not completed your name plate and the Cat Face tutorial, we can use the start of class to work on this.
If you have, you can work on the following exercise:
Create several chair models, each one using the following commands as the primary (if not exclusive) method for creating the form:
Put each model on a layer in the same Rhino file. Using Keyshot, create a rendering of the 5 chairs in one image. Post this image to the shared google drive. Name this file: FirstnameLastname_6Chairs.jpg
It’s been brought to our attention that the method for defining the stock shown in the tutorial does not work. This is a factor of some changes that were made in MasterCAM 2017 from the previous versions. Instead of clicking on the “Bounding Box” button, click on the “All Entities” button and this will work the way that “bounding box” used to work.
Sorry for this confusion.
In order to install Windows on your Mac, you will need to install Parallels. You can start with the trial version of Parallels, and download the free Student edition of Windows from https://risd.onthehub.com . Be sure to give yourself plenty of time for downloading and installing as the files are quite large. If you have downloaded your free copy of Windows 10 previously while at RISD, you will not see an option to get Windows as they only allow you to download the OS once. Check the bottom of this post for more information.
Once you download the Windows 10 ISO (the installer file) and Parallels, install Parallels first. It will then guide you through installing a virtual machine (where you will run Windows). You will need the ISO file on your computer or a USB thumb drive and your License key but the install should be fairly automated with Parallels.
This is what you should see for windows once you add it to your cart. You don’t need to add the “Extended Access Guarantee”, but this will provide you 24 months of access to download the software or view your key. Otherwise, your access to download is limited to approximately 1 month and your keys are in the confirmation email you receive when you purchase.
Can’t Find or Access Windows on onthehub?
If you previously installed or downloaded Windows 10 from onthehub, you will need to find the email that contains your license key that was sent when you originally. If you don’t have this you’ll need to talk to OIT to retrieve it or pay for a new license. You can get the ISO file (the disk image of the installer) from OIT, another student or we will try to have Marylin have a USB drive you can check out with the file.
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 have been looking into the issue some of you have been facing where MasterCAM hangs / crashes when it is loading. I may have found a potential fix for this. In digging around I have found this to solve the problem for me:
It seems as if this issue is related to an incompatibility with certain versions of Windows, Nvidia graphics processors, and MasterCAM. This solved it on my computer, but I haven’t had a chance to test this elsewhere yet.
For Monday the 7th:
1.Please complete the tutorial for surface driven cuts in Mastercam (the spoon) located on the CNC site : http://risdbankcnc.squarespace.com/surface-cuts-hidden
2.Begin developing the design of your spoon. The challenge and review in class provided a basic overview of the construction method we’d like you to use. There is a video that covers a similar process here: https://vimeo.com/111593972
Dimensions of the spoon must be within 2″ wide x 8″ long x.75″ deep. No area should be under .0625″ in thickness, and this should only be at the thinnest point where the material tapers up from there. These will be cut from solid wood so design accordingly considering the strength and grain.
For class tomorrow have sketches of your design and at a minimum orthographic views completed in Rhino, but we’d encourage you to have the 3d model at least started so we can assist with any challenges you run into.
