Installation on Linux

Rhino doesn't run in Linux. However, you can install Windows 7 in VirtualBox and run Rhino in there. If Guest Additions are installed (first on the host, then via the window menu in the client), you can run Rhino in seamless mode. See: [[1]]

Getting Started with Rhino

Get Started Modeling with Rhino

basic navigation
  • rotate: right-click
  • zoom: scroll-wheel or CTRL + right-click
  • pan: SHIFT + right-click

window tabs

  • double click to switch between 4-window setup or 1-window
  • small arrow to set viewing mode of that window

tool tabs (above windows)

  • you can drag them to change the order
importing a reference image

PictureFrame import image as reference Change object layer (under layer settings) to move image to a layer F3: Properties Tab -> materials -> Transparency (set image to be transparent)

scaling reference image

Draw a polyline of fixed length:

  • Click polyline icon
  • type 0 [Enter]
  • type 12 [enter]
  • use SHIFT key to make straight lines

Gumball in bottom line: bring out arrows to transform objects. Use Scale command to scale image

snapping

Just above the bottom line there is a listing of possible snaps. Click disable to disable all of them. Click OSnap to turn viewing the possible snaps on or off Hotkey for snapping or disable-snapping: ALT-key.

Drawing curves

There are *very* many curve types. You find them under the little triangle when you hover the Polyline icon

Revolve curve

Under the surface icon you can find different ways of turning a curve (or just three points) into a surface. Here you also find revolve. The default will make a 360 degree rotation.

When you create a surface with the record history button on, this creates a connection between the original curve and the resulting object. You can then change the curve afterwards to change the resulting object. Type history on the commandline to change recording settings. HistoryPurge can delete history from the object

Polysurface editing with Gumball You can select an edge with SHIFT + CTRL and then edit it with Gumball.

Solids -> Fillet: for rounding the corners. Make sure the red lines stay within the limits of the adjoining surfaces, otherwise the fillets will become a mess.

Cap: this command closes a surface so it becomes a solid volume.

Analyzing solids

Under Analize direction -> Show Edges you can select:

  • All edges
  • Nakes edges
  • Non-manifold edges

Wirecut: Cut a part out of a solid volume by following a curve. Result: more solids! Boolean union: Melt solids together. Shell: turn a model into a shell (so it has thickness, but is not all the way solid). -> warning: small fillets are often problematic with shells. Solution: put the fillets there AFTER shelling. -> keep Edge Analysis handy while doing that!!!

Getting a surface of from an existing surface: minute: 34 --> this doesn't work for me:

  • CTRL-SHIFT click the edge
  • CLICK + hold, CLICK + hold + CTRL, drag a new surface off the existing one.

Extract surface: take surface from a solid 36:00
