Part 1: Creating Primary Surfaces
In this section, you will use the mono-rail tool to create the two surfaces
that define the vacuum cleaner body.
In the tutorial, file the main curves have already been created and are supplied
on a layer called curves. As you don’t have to create the curves for this model,
you will be able to focus on the techniques of intersecting and trimming
surfaces introduced in this tutorial.
The curves have been created using the same techniques you learned in Tutorial
2. If you want to see how the curves are constructed, use the Control Panel
CV/Hull display to display the CVs.
If you prefer to create your own curves, you can make the curves layer inactive,
and create your own curves using these as a guide.
