For a one-button workflow to work a basic selection and workflow scheme needs to be followed.

Rapid SDK is based on an initial selection which defines driver and driven objects. Since there is no selection order in Blender but everything is based on an active object and an additional selection the system defines the selection rule: The active object is the driver and all other selected object are defined being driven.

Because of this requirement it’s currently not possible to have more than one driver object during the setup.

When setting up a driven key relationship the general procedure is to first define the starting values and, after storing these, to then define the end values of the range. Using a predefined range of motion (ROM) by having a temporary animation on the driver is a common practice and helps going back to specific values to further refine the relationship.

With these fundamentals it’s easy for Rapid SDK to identify what the driving and driven properties are; everything which changed between the start and end of the defined range will be a part of the created driver. If more than one property changed on the driver the sum of these values will be used as the driving value. If one or more properties changed on the driven object the driver will affect these individually.

Rapid SDK provides a simple one-button workflow to quickly set up driving relationships between one or more properties. It’s aimed to help simplify the steps needed to adjust particular relative values or even non-linear behaviour.

Quick Overview Movie

Obviously a one-button solution has limitations such as defining more complex driving setups (multiple driving objects) or evaluating certain properties such as colors or strings. But this is beyond the scope of this add-on.
