summary 
An isosurface is a threedimensional representation of a constant value of a field function within a given volume. They are normally used in computer graphics to visualize data in fluid dynamics, medical imaging, geophysics, and meteorology. The advantage of isosurfaces is that they can represent all sorts of topologies. That makes them a perfect tool for modeling, branching, forking, and bifurcating objects with smooth transitions. As they work of a field function, the surface is implicit, the polygonization an approximation. This is a good base for coupling performance with precision. The task was to define a set of handles to change and model an isosurface. It had to happen through the modeling of the field function in a way that is rather intuitive but without giving up the precision one is used to have from standard NURBS/BREP modeling. The paper shows how a modeling framework for isosurfaces is implemented as a plugin for Bentley Systems Generative Components allowing an intuitive way of exploring design variations. The implementation is illustrated with a proof of concept showing a sketch design.
