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:
Here are two images that can be used to simulate a caned surface as was demonstrated in class.
A basic review of how to do this:
And here are a few wood textures you can use.
1. Comment on Someone else’s project
A. Due March 2
In response to their work on the drinking glasses part of Assignment 1, write a very brief statement commenting on the work of the classmate whose last name follows your alphabetically (the last person in this order should comment on the first person). Describe at least one positive and one negative aspect of their design, but also make specific suggestions for how their renderings can be improved. This comment is required, but you are also welcome and encouraged to comment on anyone’s work. Use Google Doc’s commenting feature to do this.
2. Improve Your Post for Assignment 1
Due March 5
If your post from the first assignment had any problems, or if suggestions were made that could improve your design or rendering, you have the chance to go back and make improvements. Technically this is not required, but the improved submission will be considered for grading purposes, should you choose to revise. If you choose to improve your work, modify your document, adding the new content so we can see the improvements in relation to the original content. Don’t delete the original work.
3. 3D Print one of your glasses
Due March 12
Select one of your glasses to make a 3D print of. Save your this model as an STL and submit it for printing on one of the 3D printers in the Bank Building second floor.
4. Chair Study: Models and Rendering.
Due March 5
Working from the brief for the Chair Study project, you should create the following content:
Put your Rhino folder in your personal Google Drive folder. Begin to organize your folder with sub folders for each project so faculty can easily navigate and find your work.
Put your renderings in your personal google drive folder and the “chair rendering folder”. Come up with a consistent, logical naming convention that begins with your first name and clearly differentiates between the three series of renderings. Use this for all of your renderings. For example: Specce_Chair_Scene1.jpg, Specce_Chair_Interior1.jpg, Specce_Chair_Surreal.jpg
5. Paper Model Selections
Select and bring in several objects for consideration to use in the next project, Paper Model.
If you are using windows and installed Rhino 6, Keyshot will not recognize a Rhino 6 .3dm file. To work around this, save your rhino file as a version 5 file. Keyshot will most likely be updated to work with Rhino 6 shortly. In the meantime, the Keyshot plugin for Rhino works between Rhino 6 and Keyshot.
Keyshot is installed on the iMacs in the computer lab, for now I was only able to get it installed on one of the partitions (these computers are set up to run Windows and MacOS via Bootcamp):
They all have Rhino installed on both partitions. I have also installed the Keyshot plugin for Rhino on the iMacs.
There is a plug-in available for Rhino that enables “Live Linking” from Rhino to Keyshot:
“With LiveLinking, your modeling application and KeyShot are connected (via the plugin). With it, you can continue to work in the 3D modeling application after the initial transfer to KeyShot. At any point in time you can update your designs in KeyShot with the simple push of a button. Only the changed parts and layers will be transferred to KeyShot, without the loss of any materials, animations, lighting nor camera setup.”
Get the plugin here:
scroll down until you see the Rhino logo, click on the logo, then choose the appropriate operating system. Once you have the plugin installed, you can read the instruction below for how to use it (windows and mac have differences in how to use it).
See this page for details on how to use it:
You can download Keyshot from the link below. Select the “Full Installer” for your operating system:
You will need to get a license from me in person, but it will work in demo mode in the meantime. I will be distributing licenses at 1:30 pm on Friday (2/21) in Prov Wash.
There is a great fellowship opportunity available to sophomores and juniors, offered by Be Original (an organization that promotes authentic, as opposed to “knock-off” furniture and lighting design). From the website:
“Be Original Americas’ 7-week Summer Design Fellowship program will introduce two college students to all facets of creating innovative, high-quality products, from research, design, and manufacturing to marketing and distribution through hands-on, in-the-field learning.”
The deadline is March 12, but all you need to apply is:
To be eligible you must meet the following requirements:
Be Original Americas will provide travel and lodging accommodations as this program will require travel to New York City and member company sites throughout the United States. Participants can expect to incur some costs for food and incidentals. A $3,500 grant will be awarded to each student at the successful conclusion of the program.
I’m happy to offer any help or advice to anyone wishing to apply.
Some of the the videos I will post are sped up to compensate for how slowly I typically speak, but not all of them are. If you find a video is too fast or slow, you can get a browser extension that will let you speed up or slow down the videos as you like.
I’m sure there are similar options for Safari and other browsers, but I can’t seem to find a free one.
In both the Windows and Mac versions of Rhino you can customize the pop-up menu that appears when you click on the middle mouse button. You’ll see me do this often when I’m working in Rhino – it’s a huge productivity booster.
To customize in Windows:
Click the middle mouse button
click on the small gray bar at the top of the menu – this will “dock” the menu
remove items from the menu by holding shift as you drag them off the menu and into the workspace
add items by holding CTRL as you drag from an existing toolbar into the menu
To customize on the Mac:
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.
