App for drawing Engineering Blueprints. You can draw straight lines, curves, scroll through the drawing, add text to the drawing and move points and text in the drawing. You can add a comment to the drawing. You can send an e-mail with the drawing as an image attached to the e-mail. You can draw many drawings and give them different names. This App is free because it is supported with ads and it has the limit of drawing up to 2 curves and 80 points, if you want to have no limits, we would encourage you to buy "Blueprints App" which is here: http://AppStore.com/BlueprintsApp We focused on making an App powerful but easy to use. We were looking for an App for drawing in the App Store easy to use and we didn't find it so we decided to create one and we think we have achieved that objective with this App. Great for architecture, engineering and construction.
