Pumpkin Making With Aidan

You may have seen the tutorials on how to make a 3D pumpkin that I posted to the SketchUp Island pumpkin carving contest website.*

What's cool is that there are many unique approaches to creating a pumpkin shape, really. I just figured out one way on my own. Below is a demonstration of another way that Googler Aidan Chopra makes pumpkins, using complex curves.

Read on!
1. FOLLOW ME the arc around a circle:

2. It will look like this when you are done:

3. Erase all but one segment (see below) and use the SCALE TOOL to enlarge the center spine (in red) by 1.15%

4. Use the scale tool again on the other two spines at 1.10% (in red, at left). The finished component is on the right.

5. Now COPY-ROTATE the component around into an upside-down bowl shape (similar to step #2's appearance) and then group everything. COPY-MOVE the whole thing beneath the original, then use the scale tool again to scale that one backwards (until it is looks like a right-side-up bowl shape) on the blue axis. Type "-1 ENTER" to get the dimension exactly right. Then match the bottom half to the top half with MOVE tool, and paint!

Thanks, Aidan!
