Glad to find a thread about this matter, since I found it most bizarre that a vector software that promotes itself so vividly lacks such a basic tool. Not to mention any particular competitors, even the free ones, but even the simple vector apps have this tool. It's really surprising that there is no measurement no dimension tool. Very often I would just like to know what the distance is between some parts of the artwork.
I hope that the developers actually read this discussion and that this super important tool will arrive shortly.
