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:

1. Assign the objects you want to have this texture with a “Matte Paint” material with any color (other materials will work as well, but this is a good start)
2. Find this material in the list of in-use materials from the materials inspector, double click on it
3. Click on the “Textures” Tab
4. Assign the black and tan image to the “Color” texture option
5. Assign the black and white image to the “Opacity” texture option
6. Make sure the option for “sync” is turned on from the bottom of the textures properties
7. Adjust the scale as needed with the slider or by entering a number in the field associated with the scale slider

And here are a few wood textures you can use.

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.

The commands covered in this video are:
Trim
Split
Join
Explode
Cap
Fillet (with radius set to a value of 0)

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.

Understand the basics of navigating the view of your model is an essential skill for Rhino. Here is a review of 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.

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.”
