I stumbled across this plug-in by accident when I was googling for an alternative to the dimensioning features of CADtools, and I am very glad that I did. Although the interface takes a bit of time to learn, it is extraordinarily flexible and direct to use, with much use of modifiers to qualify the defaults, e.g to switch to external arrows, displaced text etc. It blows away any other dimensioning tools I have come across.

The price is quite reasonable compared to the alternatives, and the dev’s other tools are well worth looking at too. In fact together with other offerings, such as PathToolkit and SnapMeasure, they could constitute a cheaper—and in some respects better—alternative to the excellent but over-priced CADtools.
