1 Rhino Tutorial Modeling a remote control in Rhino 1 on Sat Sep 25, 2010 6:57 pm

In this tutorial, you will model a simple remote control with Rhinoceros 3D, similar to the one on this image. There are no flat surfaces in this model, so almost all of the main surfaces will be created using sweeps, revolves, etc... Skill level is novice to intermediate. [You must be registered and logged in to see this image.]
First we will draw the outline of the remote in top view. Don't try this with a freeform curve tool. Instead, use a combination of arcs and trim or split pieces away.

First draw a circle, with its center point placed at 0,0,0 on the grid.

Use the arc tool 'start-end-direction' to draw the side of the body, and mirror this curve around the main y-axis. You can use grid snap to help.[You must be registered and logged in to see this image.]
To close the curve opening at the bottom, we will use 'blend curves'. Blend makes a smooth transition between two open ends. By using blend, you can be sure there will be no sharp corner where the curves meet.

Go to the curve menu, and choose 'blend curves'. Pick near the two end points and the blend will be created.

The shape is not 100% what it should be.

Select the blend and turn on its control points. We will add one more control point exactly in the middle of the curve.[You must be registered and logged in to see this image.]
Press long enough on the 'control points on' button to let the underlying buttons fly out. Choose 'insert knot'.[You must be registered and logged in to see this image.]
With mid snap turned on, click at the midpoint of the blend. A new control point is created.[You must be registered and logged in to see this image.]
Select this new point.[You must be registered and logged in to see this image.]
Move the point down, with ortho snap on (or leave it off and press 'shift' whike you drag, this does the same as ortho snap). Move it downwards untill the blend looks good. [You must be registered and logged in to see this image.]</A>
This is what we have so far. Join the 3 curves at the bottom.[You must be registered and logged in to see this image.]
Draw a straight line from the endpoint of the left curve (use ortho or shift!). Mirror this line along the Y-axis (use grid snap). [You must be registered and logged in to see this image.]
Select the circle and the two straight lines. [You must be registered and logged in to see this image.]
Select the bottom surface, and the curves that you used to create it. Move them all a bit higher.[You must be registered and logged in to see this image.]
Close the gaps with blend curve.[You must be registered and logged in to see this image.]
In the front viewport, draw an arc with 'start-end-direction' and use the grid to make sure it is symmetrical (count the units on each side of the green axis).[You must be registered and logged in to see this image.]
Make it something like this, don't curve it too much.

In top view, move the curve upwards so that it is higher than the circles top.
[You must be registered and logged in to see this image.]
Extrude the curve like in the image on the right.[You must be registered and logged in to see this image.]
In the right view, draw a curve similar to this one. Use the 'control point curve' tool, don't mind about how accurate it is, we will adjust this later on. Don't use too many points! I used only 7 points.

Turn on control points for this curve.
[You must be registered and logged in to see this image.]
Adjust the points by moving them in the right view until the shape looks smooth and clean. Make sure you don't accidently snap to other curves while you are moving these points![You must be registered and logged in to see this image.]
Select the arc you created earlier and mirror it like this:

Use 'transform-move' together with object snaps to move the mirrored curve. You should move it from its midpoint, and move to the endpoint of your bottom curve (see image).[You must be registered and logged in to see this image.]
Now use 'transform-copy' to copy this curve to the other end point of the bottom curve. Again, use object snaps for this!

Select this copied curve.
