This really only applies to the Circle Pack 3 and 4 challenges. One of the last things I worked out. The 2 is easy enough, since they meet at the center, and the 7 is 1/3 diameter, which can be worked out with a few moves.

Give it a week, or...

No...

Projection.

Spoiler...

Draw the big version first. Later you'll want to go back and only draw part of it.

Spoiler...

You need the large circle center, a small circle center, and a single point on the circumference of both.

Spoiler...

Draw a line from the center of the large circle through the center of the origin circle.

Spoiler...

Draw a line from the circumference point to an equivalent point on the origin circle. This line must be distinct from the center line.

Spoiler...

Extend the two lines to an intersection point.

Spoiler...

Draw a third line from the intersection point, back through the center of the smaller "packed" circle.

Spoiler...

A point on that line, where it crosses a line drawn between the origin-based points used for the first two lines, is the center for the first origin-packed circle.

Transferring that around to the other circles should be easy enough.
