Hi, We have undertaken a project which aims to replace paper forms. T

From the architectural point of view, my view is that you need to break down your forms into unique data elements. For e.g. You may have an insurance form. There will be one form for all kind of insurance - although some data elements may be common, such as customer details and policy info, other information may depend on the type of insurance (for e.g health, car etc). So you need to decompose your data model into finite entity sets and build your processes around it. I would recommend starting from entity to process. Doing the other way round may most likely lead you to lots of changes down the lane. Once you get the entity in place, the rest is mapping the entities to a CDT or so.
When it comes to rendering the form, you can literally do a lot here. You can use the CDT to create your form or define the form definition externally and invoke it dynamically - and many more. Check a sample concept I'd uploaded under Library & Utilities (Shared Components) called dynaform-designer. This might give you some idea.
