Several improvements to annotation and dimension alignment are available in Draft, PMI, and in sketches.
The Line Up Text command now aligns text for more annotation types. The expanded list includes datum frames, edge condition symbols, feature control frames, surface texture symbols, text boxes, and weld symbols.
Two new options on the Line Up Text command bar align annotations and linear dimensions using their leader break points instead of their text range boxes.
Vertical Break Point—Aligns the leader break points of the selected elements vertically.
Horizontal Break Point—Aligns the leader break points of the selected elements horizontally.
As you move a linear dimension (A), you can locate another dimension to display a dotted alignment indicator (B). When you release the mouse button, the first dimension snaps into collinear alignment with the second.
You also can use this technique to move a radial dimension so that it snaps into concentric alignment with another radial dimension.
You can drag the terminator of a datum frame or feature control frame (1), so that it snaps to the dimension line it references (2).
