`1. For Linear dimensions:
If the text is aligned to the dimension, there are 3 options: Above, Centered, Outside. “Outside” doesn’t seem to do anything different that “Above”, and the User Help doesn’t mention it.(?)
`2… Angular dimensions can set to be “aligned to Dimension”. But there is no alignment. that I can see. The text should be parallel to the radius line.(?)
`3. Usually, you can edit dimension text with double click. But if you make it too long (say 30 chars) then double click won’t work. You have to context click to edit.
