I cant work out why Adobe creates png files. I have old Adobe ideas files and these work fine as vector graphics, but draw just keeps creating png files when I need vector, can you help please
Sadly you can't. The model Adobe has set up is that you need to send the file to Illustrator, and can only send to Illustrator CC - not even CS6. Even though I have CC and can use the feature, it is really annoying that it can only spit out low quality pngs as sometimes I want to just knock up something quickly on my iPad, export it and mail it on. The only real option is to stick to using Ideas.
Updated: It looks like they may have lifted the restriction on you having to have a Creative Cloud account as of the last release, so maybe you can now export to CS6
Updated even further!
Yes, the current version of Adobe Draw exports as PDF which will support your vector outlines.
