With an emphasis on generative design comes the need for better T-Spline manipulation tools. The generative tools are amazing, but the output T-Spline body is usually not very good looking. The Alias speedform software which is the exact same T-Spline environment as Fusion has two tools that would help tremendously in cleaning up generative mesh models.
The first one is "Edit By Curve" allowing a number of T-Spline vertices to follow a curve is super helpful in cleaning up a mesh.
The second one that would be extremely helpful is the ability to define the pull direction for vertices in relation to a curve. Also already implemented in Alias Speedform in terms of 2D pull and 1D pull.
Both of these features have been in Alias Speedform for almost three years and would be quite useful for cleaning up Generative design bodies as well as controlling T-Spline bodies in general.
