Aligning text on a curve
If you type several lines of text on a curve, the text slopes following the angle of the the start of the curve. You can control the direction the edge of the text follows by adding a very small segment onto the start or end of the curve.
To align text on a curve
1. Draw the curve you want the text to follow.
2. Zoom in to the end of the line, preferably to maximum zoom level.
3. Choose the Shape Editor Tool.
4. Click on the end point handle on the curve to select it.
5. Click the Straight Lines button on the Shape Editor Tool Infobar.
6. Click to create a new, very short line segment. This line segment should be perpendicular to the direction you want the left-hand edge of the text block to follow. If you need the segment to be exactly horizontal or vertical, CTRL-drag the new point.
7. Now type the text on the curve as normal.
