If you discovered this Rhinoceros 3D tutorial page through a direct link or search engine, please note that you're on page 2 of the tutorial! Please complete the previous page first if you haven't done so.
In the front viewport, turn on control points for this curve. Select the two endpoints, and then use 'scale1D' to scale the points in the x direction. Use the Z axis as the scale start point (use grid snap to snap to it!).[You must be registered and logged in to see this image.]
Select the middle point and move it down (ortho or shift!!). We now have a much more curved arc.

Turn off control points (hit esc a few times)

Use move to move the curve from its midpoint to the bottom curves endpoint.[You must be registered and logged in to see this image.]
Use sweep 1 rail to create a surface from these curves. The bottom curve is the rail, and the 2 arcs are the cross sections.[You must be registered and logged in to see this image.]
This is what we get, a double curved surface (this is much nicer than when we would have use a straight extrude for example).[You must be registered and logged in to see this image.]
This is how it looks in shaded mode.[You must be registered and logged in to see this image.]
In right view, create an arc like this:[You must be registered and logged in to see this image.]
Once again, move this arc from its midpoint to the midpoint of the circle (see image - click to enlarge).[You must be registered and logged in to see this image.]</A>
From these two curves we will create a surface, also with sweep 1 rail. The closed curve is the rail, and the arc is the cross section. In the sweep options, make sure freeform is on and also 'do not simplify'. These are the default sweep1rail settings.[You must be registered and logged in to see this image.]
It should look like this.[You must be registered and logged in to see this image.]
Use trim or split to cut away the exessive surface parts. If trim or split doesn't work, you probably created surfaces that do not intersect properly. The main body looks a bit too thick, so undo the trim/split.[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.]
Again trim or split. Now it looks better. Join the surfaces into 1 closed solid.[You must be registered and logged in to see this image.]
Use fillet edge to round the edges a bit (don't use a very big radius).[You must be registered and logged in to see this image.]
Select all the curves in the scene, and move them to another layer to keep things organized. [You must be registered and logged in to see this image.]
In the right view, make thin rectangle like in the image:[You must be registered and logged in to see this image.]
Use 'solid-extrude curve' to make it solid. [You must be registered and logged in to see this image.]
Now use boolean difference to cut away the rectangle from the main body.

Go to 'curve-curve from object-duplicate edge' to duplicate the edge on the top solid.
[You must be registered and logged in to see this image.]
Select the duplicated edge, and use 'curve-offset curve' to ofset the curve a certain distance. You can enter a value or you can turn on the 'trough point' option.


[You must be registered and logged in to see this image.]</A>
This is what it should like (enlarge the image). [You must be registered and logged in to see this image.]
Select only the inner curve and use solid-extrude to make it solid. Use the both sides option so it extrudes in the top and bottom half of the main body.[You must be registered and logged in to see this image.]
Use solid-union to union the two halves and the middle solid together. [You must be registered and logged in to see this image.]
This is how it looks like:[You must be registered and logged in to see this image.]
In top view, draw a circle with its midpoint on the 0,0,0 point on the grid.[You must be registered and logged in to see this image.]
Project this curve onto the main body, and delete the bottom projected curve. [You must be registered and logged in to see this image.]
