Variable Fillet

Plane with arrow pointing downwarc, Finished surface fillet

Tip: If the option window has disappeared, select the fillet first and then go back to Palette -> Surfaces Surface Fillet —>$

You can also create some very interesting variable fillets:

• In the option window, click on Undo All.

• Set the Construction Type to Variable.

• Click on the sphere, but this time have the arrow of the point outwards.

• Click on the plane, and have the arrow of the plane point downwards again.

• After accepting both selections, click on the edge to create another radius.

• Change that radius by typing 0.5 in the promptline.

Tip: You can move the new radius along the edge by using the MMB.

• Click on the Recalc button in the options to see the new fillet.

Partlines

There are many different ways to create partlines in StudioTools. For simple geometry, you can use the Surface Fillet Tool from the previous exercise and just create an opposite part.

• Select all three objects.

• Group them together.

• Move the duplicate over to the side.

• Select the original surface fillet as a Component.

• Go back to Palette —> Surfaces —> Surface Fillet —>

This will open up the option window again because of the construction history.

Move the duplicated group to the side Select original fillet

• In the options, click on Undo All.

This will revert back to the original surfaces.

Conclusion

• Click on the sphere again, make sure the arrow is pointing inwards and click Accept.

• Click on the plane again. This time the arrow needs to point upwards.

• Click Accept.

Reverted surfaces New surface fillet

• Select the part duplicated earlier and move it back to 0.

This will create the visual effect of a partline going around the sphere.

Conclusion

In this lesson, you learned all the main techniques for creating a curve on surface, as well as how to trim surfaces and how to round off edges. You are now ready to implement these new tools with the Wheels project in Lesson 6.

In this lesson you will learn how to use the Revolve and Surface Fillet Tools to model wheels. You will create the rim and tire, and then apply shaders and textures to

create a realistic effect.

In this lesson you will learn how to:

• Create layers;

• Create the rim;

• Create the wheel;

• Create spokes;

• Apply a tread pattern;

• I mport Adobe Illustrator^® files.

Lesson

Layers

Layers

Before you start working on the wheel, create some new layers to better organize your file. Layers in StudioTools work similarly to ones in other software packages; they allow you to view/hide specific geometry, add symmetry, and keep your file nicely structured.

Start a new file and create a new layer by going to:

Studio —> Layers —> New.

Rename it Curves by double-clicking on its title with the LMB.

Create an additional layer and name it Wheel.

If the curves layer is active, as indicated by the beige color, then all newly created geometry gets assigned to it automatically.

Click on the layer with the RMB to see its options:

Visible = Toggles visible or invisible content

Symmetry = Creates a mirror image of your geometry Assign = Allows you to assign active geometry to this layer Pick Objects = Picks everything assigned to this layer

Create new layer Layeroptions

Rim

Start to create the rim by using the Revolve Tool.

1 Revolve

Create a new curve in the side view, which will be the cross-section of the ri m. When placing the CVs, make sure that the first and second CVs are on the grid and are perpendicular to the X-axis by holding down the Alt key when you place them.

Note: If you do not place the CVs perpendicularly, you will get a pinch in the center of your rim later on.

103 Go to Palette ---> Curves -> New Curves -> New Curve by CVs.

In the side view, place the first CV at the origin.

Place the next CV vertical on the Z-axis.

Continue to place a few more CVs as shown.

With the curve selected, go to Palette -> Surfaces -> Revolve ->

In the option window, set the Revolution Axis to X, the Sweep Angle to 60, the Sections to 4 and click on Go.

This will create a section, which you will later duplicate to create a whole rim. Notice that the revolve is green, which indicates that it has construction history on it.

2 Skin

Create a curve in the back view, which will function as the hole that you will cut out of the revolve shape. Make sure the curve sits in the center of the geometry. The curve will have to be closed before you copy it to create a skin surface.

• Palette -> Curves -> New Curves -> New Curve by CVs.

Make sure the curve has no sharp turns, otherwise the Round/Fillet Tools will not work properly later on. Also, make sure that the last CV is not too close to the first one.

• To close the curve, go to Palette -> Object Edit -> Close.

• Click on the curve once.

This will make a closed shape out of the open curve.

Skin between the curves Lesson 06

Open curve Closed curve

• Duplicate the curve.

• Move the copy to the opposite side of the revolve so that you can skin in-between the curves.

• Palette Transform Local —> Center Pivot.

Now you can scale the curve and it will hold its relative position.

• Skin between the two curves.
