Chapter 4 Using Plugins Effectively
You could have done this in many other ways, too. If you had created four guiding arches,
then the Extrude Edges by Rails method would have worked. In addition, the Skinning tool from
the Curviloft plugin would lead to the same result.
Next, let’s create a hypar shell (a hyperbolic
paraboloid):
1. Draw a square (30f × 30f, for this example) and
delete the internal face so that you are left with
only edges, as shown here.
2. Move a corner point upward (by 10f along the
blue axis) using the Move tool.
3. Repeat this with the corner point on the opposite
side. You should now have two opposing edges
“on the ground” and the other two “in the air.”
4. Now select all four edges and click on Generate
Soap Skin from the Soap Skin & Bubble toolbar.
This adds a temporary set of faces into your edges.
5. You now have the option to modify the number of divisions in the Measurements
Box. The default is 10; enter a different value if you want a more detailed mesh. Then
hit the Return key and watch how the plugin fits the surface between your edges.
