Me and my team have been trying to get rid of this situation for years, so we finally came out with a tool to help. It is pxCode, no more measurements and handoff tools, no more hand-coding and code gen, but you can still hold the complete control on your Layout and Code. Should definitely try it if you're into creating Responsive Webpage.
Check out www.pxcode.io
