I was asked how to design your own scalloped circles using Silhouette Studio. This can be done in either version.
Here are the scalloped circles I'll show how to make, using basically the same steps each time.
1. Draw a perfect circle using your "elipse" drawing tool. You can make it a perfect circle by holding the shift key while you drag out the shape. Make it 0.825".
2. Go to your Replicate window (looks a bit like a flower). With your circle selected, choose "Row of Three".
3. Select all of those circles, then choose "Rotate Three Copies" while still in the Replicate window. It should look like this:
5. Draw another circle that will fit inside the outer ring of circles. This is what you'll use to fill in the holes in the center when welding. This circle is 1.74".
7. Select all the circles again and choose "Weld". (Bottom icon, looks like a grey rectangle and circle overlapping.)
Now for the variations:
To make the scallop circle from the top image that looks like a flower:
Steps 1 & 2 are the same.
Step 3: Choose "Rotate Two Copies" (instead of three)
Steps 5 & 6: Your inner circle will need to be more precise. Make sure it's big enough to cover the holes in the center, but not so large that it overlaps the very outer edge to interfere with the scallops. (This circle is 1.420")
For smaller, closer scallops, you can make this variation:
Step 1: The circle is 0.50"
Step 2: Make it a "Row of Four" instead.
Step 3: "Rotate Five Copies" so it will fill in the gaps due to a smaller circle.
As you can see, these might be fun sketch designs for flowers before welding, too. Just for fun, I made a very small circle (0.345"), but had to choose my "rotate copies" in several combinations quite a few times until the edges were filled in. Because you're welding, it doesn't matter that there are some circles with many many layers in the same place.
Once you've created the scallop combination you like, these can be resized to fit your project. Have fun experimenting!
