In-line leader in a Place Note disappears when dwg file is saved.
Use Change Dimension tool to reset to active Dimension Style and in-line leader returns. But save the dwg file and the in-line leader disappears again.
This is an AutoCAD limitation. If the angle between the leader and in-line leader is less than 15 degrees, AutoCAD will eliminate the in-line leader.
Solution is to move the Text portion of the Place Note so that the angle between the leader and in-line leader is greater than15 degrees.
