"rope"

[ "rope", "name", [x1, y1], r1, [x2,y2], r2, state ]

Tangent line to two circles with center and radius given. Negative r values select the tangent point on the left side from the line C1-C2. Represents ropes running between disks.

• "name" label text, typeset as normal text. Add \\( and \\) to enforce math mode.
• [x1, y1] center of first disk
• r1 radius of first disk (can be zero, then line starts at the center)
• [x2, y2] center of second disk
• r2 radius of second disk (can be zero, then line ends at the center)
• state (optional, default: "SHOW") "hide", "show" or "HIDE, "SHOW"
