Described is a system and method for converting a drawing (or captured image) of a layout using a trained image analysis model (or engine) into a structured document template. The mechanism may allow a user to create a hand-drawn diagram of a layout that can be automatically converted into a template for a document. For example, the hand-drawn diagram may be of a layout for an email which the mechanism may automatically convert into HTML code for an email template within a building tool. The building tool may then use the converted email template as part of an automated email marketing procedure. Accordingly, the mechanism provides the ability for a user to conveniently create a template and forego the process of using only programming code or visual tools.
