|Draft → Utilities → Flip Dimension|
|Introduced in version|
This tool flips the Draft Dimension text around the dimension line. It can be done to adjust the appearance of the dimension.
What this tool does internally is to invert the normal direction of the dimension, which is used to position the text.
Draft Dimensions also have a DataFlip Text property which, when it is , rotates the text by 180 degrees around the normal direction. By combining these two features, flipping the normal direction and flipping the text, you are able to make the text appear correctly in all possible situations.
