In planview, it is not very nice to have text unreadable on a line. But in the same time is a lot of work to rotate and set position from Attributes (Texts).
This routine makes perfect to select all Blocks or one by one on a Polyline and rotate them after Polyline direction. Also, you can change the Position of the Attributes up or down the Polyline.
