Curves for the bevel
Tip: If you sketch the curves on the layer that has symmetry on, you will get better visual feedback of what the complete outline will look like.
• In the top view, select the surface and project the inner curve onto it.
The curve on surface that is created becomes part of the surface and you will later use this curve to trim the rail surface.

For the second curve, you will change the options when projecting. Make sure you are back in the top view and go to:
• Palette Surface Edit —> Create curves on surface —> Project —> O.
• In the options, select Create Curve and turn off Match Original and Create History. This will allow the newly created curve to have additional CVs so that it follows the shape of the surface better.
Click Go.
Click on the second outer curve in the top view.
This will create a duplicate that follows the rail, but unlike the curve on surface, it is not attached to the surface, meaning you can move it around.
Move the projected curve slightly down in the Z-axis.
This will create more of an angle between the two curves.
• Trim the rail surface, keeping the inner part.
This will become the face of your product.
LEARNING DESIGN WITH ALIAS'" STUDIOTOOLS.,
Create a small curve that connects on both the edge of the trimmed surface and the end of the projected curve.
Use the snap-to functions to make sure the CVs touch both curves.
Repeat the process for the other side as well so that you will have two generation curves.
Change the number of rail curves and generation curves each to 2, and make sure the continuity for the generation curves is set to i mplied tangent.
Click on the small curves first, then the edge of the trimmed surface, and finally the projected curve.
Notice that the rail surface is distorted with many isoparms. This is caused by the trimmed edge.
• In the rail options window, click on Rebuild for both rail curves.
Notice how the rebuild option optimizes the rail surface and creates cleaner geometry.

3 Draft
Use the Draft Tool to create a surface from the edge of the rail.
• Assign all curves to the curves layer to make them invisible.
• Go to Palette —÷ Surfaces Draft Surfaces Draft/Flange —>
Leave the option window open.
• Click on the lower edge of the rail and confirm the selection by clicking the Go button.
You will immediately see a draft surface that is pointing upwards.

• In the option window, change the Angle to 180° and make sure you have the desired Surface Depth.
The Draft Tool is a quick method for creating accurate linear surfaces.

Tip: Try to click+drag on the draft locator to interactively change the surface.
You can also enter precise values into the promptline.
4 Bottom
• Create a plane that intersects with the draft surface.
Make sure that the plane fully intersects the draft, but that it only goes to the centerline.
• Use the Surface Fillet Tool with a small radius to create

Turn on symmetry on the surface layer to evaluate the finished shape.

Select only the top surface and create an offset by going to:
• Palette Object Edit Offset.
• Use the LMB to adjust the offset distance.
• Click Accept when the green preview is slightly above the model.
Alternately, you can also enter a precise number for the offset in the promptline.
You now have a floating surface as shown. This offset surface will be used to create an additional raised detail to the design.
In the top view, create two additional curves for the surface detail. These can be any freeform shape that you like, as long as the second CVs are perpendicular to the X-axis.
• Still in the top view, project the inner curve onto the offset, and the outer one onto the original top surface.
In the project options, remember to switch back to curve on surface.

• Trim out both surfaces so that you will get a small floating surface above the cut area beneath it.
• Create two more curves, snapping them to the edges of the trims.
Try to create the new curves with edit points; that way, you only need to snap the first and last CVs onto the trimmed edges.
Trimmed screen area Generation curves
To make the curves tangent to the surface edges, go to:
• Palette —> Curve Edit —> Project Tangent.
• Click on one end of the curve, then click on the edge of the surface next to it.
The curve will bend to become tangent to the surfaces.
• Repeat the process for the other end of the curve and the other surface edge.

• Repeat the process for the second curve.

• Use the Rail Tool to create a surface.
In the options, choose tangent for the continuity of the rail curves and implied tangent for the centerline. You may also have to use the rebuild option for one of the rails.
• Assign all curves to the curves layer and turn on symmetry to see the result.

6 Detail
Now that the basic shape is done, try to use the previously covered tools to create some refined details such as partlines, buttons, antenna, camera, etc.
Conclusion
Conclusion
In this lesson, you learned how to apply the tools introduced earlier onto a real project. In addition, you learned how to create draft surfaces and tangent surface details such as the screen area. The last step gave you a preview of the vast options of detailing possibilities, which you will now use towards the next assignment.
Assignment 4
Using these new techniques, design and model your own product and render it full screen. Pay attention to detail, clean surfaces and material/color indication.

"In this image, Jeff used hidden line rendering techniques to enhance some of the additional detail views. I like how this creates a story between the small Orthographic views, the exploded views, and the final finished rendering."

"Nairi modeled her mask and snorkel over an existing mannequin head. I like the use of multiple views to better describe the whole design. Notice how the curves of the mask have an even flow from all angles, and how there are no visible seams between the surface transitions."
