I am curious to know what UI designers are using to produce redline documents. My own team has been using a combination of Sketch to design and measure distances, sizes and styles and using Evernote's Skitch to annotate the designs with measurements.
It would be ideal if Sketch let you export files with all the properties and measurements revealed. After all, they already built the measuring engine so it would just be a matter of exporting those values. I even requested that as a feature update back in the Sketch 2 days.
In any case, can everybody point me to the tools/plugins they use to produce redline documents?
