I think you'll find that the insertion point of the text is the same as the centre of the circle (Top Left) and each text is preceeded by a space. The line is a shortest route problem, so you perhaps find the convex hull of each set of points (H & H1) as a starting pint, work from there then remove the longest segment.IIRC the last time this came up was about 1.5 - 2 years ago (no more) on the Autodesk forums
