Model = Solid
Patch = Surface
Fusion offers solid and surface modeling tools.
The terms Model and patch workspace is really often a lingo issue when talking to others or explaining the UI and where the solid and surface modeling tools are.
The logic behind naming it Model and Patch can be understood but I simply think it is not really effective because in model you talk about solids and in patch you talk about surfaces.
In patch workspace I deal wit surfaces while NURBS uses a square patch as a building block.
A patch is also more the sub element of surfaces.
Thats why I propose to use more logical and similar terms for the modes based on the geometry they generate
