No New Documents

Does not allow you to create new Visio documents. Only allows you to annotate exisiting documents.

Great app

I’m absolutely satisfied with this tool. It allows me to make notes and changes in visio drawings just on my Macbook. It shows shape data, layers and hyperlinks. And what I like most is the possibility to save the drawing with inserted annotations.

Awesome app to annotate Visio drawings on Mac

VSDX Annotator is an efficient tool for collaboration on visio docs. I use it to annotate the drawings from my colleague and send it back, then he makes adjustments. It is so convenient and reduces much time when improvements are needed.
