iSymmetry - Pattern Painting

I like this app it’s been great helping me generate patterns, but it would be helpful if you could selectively edit lines,not just delete the last thing drawn, also the ability to export and import as an STL file would be epic!

I love this app! The one problem I have repeatedly is that when I’m working on it and click the back button to undo something, it erases rows of my work. It will not ever return to what I had made and I have to start all over. This app is amazing, and if that one error we’re fixed this would be a 5 star rating.

First, I would like to say that the app is a good concept. It does need a little work. There appears to be nothing on the app interface to upgrade or even describe an upgrade. The App Store description shows in-app purchases for upgrade and additional brushes. I would gladly consider purchasing if I knew what these were and also how to purchase. Please fix or revise your App Store product info. I will consider more stars if fixed.
