We are working on fixing this issue. Hope to iron things out shortly.

If you have the Apple Magic Mouse and are using it with Rhino, you might find there are some things about it that are not ideal. There are a couple of tricks that might improve the behavior the mouse that you can try setting up.

If the virtual “scroll” is too fast, go to Rhino > Preferences > View > Zoom, and change to Scale factor value to a value closer to 1 to slow down the zooming speed.

You can also try the third party mouse control application called Magic Prefs that allows you to make more detailed adjustments to the mouse settings than the System Preferences panel allows.

Rhino will be available from the RISD store on Thursday (they’re sold out but a new shipment is on the way). It’s in one of the locked cases in the back, so you will need to ask for it. But be sure to get the right OS. With a student ID, it should be $80. Regular student licenses are more expensive ($195), so don’t get it anywhere else but from the RISD store.

Here’s a link to where you can purchase the educational license of Keyshot:
https://buy.keyshot.com/products/keyshot-hd-animation-education-version

You will need to supply proof of educational status, and they approve the purchase during business hours (M-F, 9am -6pm PST) so you’ll need to keep that in mind.

On Windows you can get a plugin for Rhino that lets you work between Keyshot and Rhino a little bit more easily. Get it here:
https://www.keyshot.com/downloads/plugins/

In the meantime, you can use the trial version:

By now I am hopeful that you all understand the basics of navigating the view of your model with the various functions we discussed in class.

Zoom (remember, zooming focuses on the cursor position)

• CTRL (windows) or Command (mac) + hold right click and drag forward (in) and backward (out)
• scroll wheel up and down
• pinch on trackpad (mac). You should use a mouse though.

Pan

• shift + hold right click and drag
• two finger drag on trackpad. Again, use a mouse.

Rotate (aka tumble, orbit)

• hold right click and drag
• two finger hold click and drag on trackpad. But of course, you will be using a mouse

Sometimes when you are viewing your model, you can get lost. This can happen if you zoom in or out to far or your rotate away from your object. When this happens, you can Zoom the “Extents” of your workspace. This means that the “camera” will reposition to display all of the objects contained in your workspace. To do this you can:

• click on the “ZoomExtents” button from the toolbar (looks like a magnifying glass surrounded by four triangles
• from the drop down menu select View>Zoom>Zoom Extents
• Type the command Zoom”, then pick the option “Extents”

Another thing that sometimes happen is you either can’t zoom in, or out any further than you are, or when you rotate the view, your object doesn’t stay centered in the viewport. This happens when the “focus” of the “camera” is not where you want it to be. A useful command to remedy this is Zoom Target. This allows you to select a point to recenter the focus of the camera. To do this you can:

• click on the “Zoom Target” button from the toolbar (it is the right click function of the “Zoom” button, which looks like a magnifying glass that is partially over a square drawn with dotted lines
• from the drop down menu select View>Zoom>Zoom Target
• type the command “Zoom”, then pick the option “Target”

Once the command is running you will be prompted to select a new target. Click where you want your target to be placed, then you can draw a rectangle to establish the extents of the view.

If you are wondering: “Can I keep my Rhino license and move it to a new computer when I get one? Or will I have to buy a completely new license?”

This is a great question. You own the Rhino license and it does not expire and is not tied to a single installation or machine. The terms of licensing agreement are the same for Windows or Mac in this regard. So, the answer to this question is:
If you get a new computer, you will certainly be able to install Rhino on it. You will not need to buy a new license when you switch. Furthermore, you will be able to keep the license on your old computer, or if you get a second computer, you can install it on the two computers you own.

Remember that the license is per OS though. You need a separate license for Mac and Windows.

Here is the official language from Rhino:

The license agreement allows you to install your Rhino on all of the computers you directly control, provided you can show your Rhino will only be running on one computer at a time. Rhino is licensed on a “simultaneous use” basis and not on a “per installation” basis.

Here is the detail from the EULA:
“Robert McNeel & Associates grants you the non-exclusive license to use the Software on any computers owned by you so long as the number of simultaneous users does not exceed the number of licenses you own.”

• You can not “loan” your Rhino to a friend or family member.
• Educational Licenses are not transferrable / saleable

Rhino is a really excellent, very valuable piece of software and students will be expected to comply with the licensing agreement of the software and to run legitimate, legally licensed copies of the software. Please understand how much value software provides and the significant discount you have available to you. If you are having a hard time with this, think about how much value you get from software and how much it costs compared to other tools, materials, and supplies you use in your work.

Many of the videos we post are recorded on a Windows computer. Some of you might prefer your setup to look more like the Windows version of Rhino. Here’s how Rhino approaches this:
“By default, Rhino for Mac presumes you are not coming from Rhino for Windows. If you would like to see Windows-esque toolbars, navigate to Rhinoceros > Preferences > Themes and select Rhino for Windows. You will need to start a new modeling window for these changes to take effect.”

If you need a refresher, here is a review of the Rhino interface.

And here is a review of the various kinds of geometry you can work with in Rhino.

The drinking glass assignment requires that you take a screen shot of your revolve curves. Here’s how to do this:

Windows and mac:
Make sure the viewport you want to capture is active, then run the command – ViewCaptureToFile.

Also FYI:
the Mac OS has an easy to use screen capture tool built in. Press Shift+Command+4  and a cursor will appear that allows you drag an area to capture as a screen shot. You should hear a shutter sound, this means that the image is saved to your desktop.

Windows has a built in app called “Snipping Tool” that can be used for screen shots.

If you’ve seen Part 1 of the Drinking Glasses Demo videos, then you’ve gotten a taste of what the PictureFrame command can do. This is a great tool and I use it all of the time if I need to bring in an image to use as an underlay for tracing, modeling, reverse engineering, etc, etc. Here is a more in-depth look at how it works.

Part 3: This Video demonstrates how to do a basic rendering with Keyshot, including how to set up the kinds of materials you may want to use for this project.

Part 2: How to measure the volume of your glass.

Commands used in this video:

• box

Part 1: Software
Purchase and install Rhino and Keyshot. Purchasing this software is not optional.

Part 2: Tutorials
Complete the “Pull Toy” and “Flashlight” tutorials from the Rhino 5 user’s guide.

Part 3: Glasses
Working from the brief for Project 1: Glasses, create the following content:

1. Description
Write a brief text description of your design proposal. Your description must include the following content:

• 1 sentence profile of the museum, include the name of the museum, location of the museum, area(s) of focus (for example: contemporary art, civil war history, New England wildlife, etc)
• why your design is appropriate for this context
• 3 descriptive adjectives that characterize the aesthetic qualities of your designs

2. Development Sketches
Sketching is versatile tool for a designer, and is particularly helpful to resolve forms and solve modeling challenges when working with 3D CAD. Use sketching to develop the initial concept and form of your glasses’ design. Sketch on 8.5” x 11” sheets of paper. Scan or take legible photographs of the sketch(es) that guided your modeling. We recommend using Photoshop to clean up this image. Bring your sketches to class next week.

3. Rhino File
Your Rhino file must satisfy the following criteria:

• Each glass must be modeled solely with a single revolve
• Each glass must be a solid
• Place each glass on its own layer and name the layer accordingly
• Place each revolve curve on a sub-layer for each glass and name the layer accordingly
• Any construction geometry worth saving should be placed on a layer(s) with clear, logical naming and organizational strategy
• Align the revolve axis of each glass with the origin’s (0,0,0 point) Z-axis, with the base of the glasses resting on the Top CPlane

Put this file in your personal folder on the Google Drive. Name this file Lastname_Glasses.3dm

4. Rendering
Include 2 Renderings of your glasses:

• Front orthographic view showing all glasses
• Perspective view showing all glasses

Your renderings must satisfy the following criteria:

• horizontally align the glasses so they form a neat row, arranged in the following order (from left to right): wine glass, pint glass, water glass, juice glass
• leave equal spacing between each glass
• save your renderings in JPG format, with a maximum width of 800 pixels

5. Screenshot
Include a screenshot of your revolve curves with the control points turned on. Your screenshot must satisfy the following criteria:

• compose this screenshot in an orthographic view
• explode any joined curves
• horizontally align the revolve curves so they form a neat row, arranged in the following order (from left to right): wine glass, pint glass, water glass, juice glass
• leave equal spacing between each revolve curve
• save your screenshot in JPG format, with a maximum width of 800 pixels

6. Google Doc
Create a google doc that includes all of the content listed above, in the order indicated below:

1. Orthographic Rendering
2. Descriptive Paragraph
3. Perspective Renderings
4. Screenshot of Curves
5. Image(s) of Preliminary Sketch(es)

Save this document in your personal folder on the Google Drive, and copy it to the glasses assignment folder.  To do this use the ‘move to’ option when right clicking on the file, navigate to the Glasses Assignment folder and hold down the option/ctrl key to enable the ‘add here” function. This is how many assignments will be collected. Name this file Lastname_Glasses.
