Plasticity’s published 26.1 release notes describe expanded Align behavior for curve-to-curve and vertex-to-vertex operations, with G0, G1, G2 and G3 continuity options. The release also improves placing mesh and instance objects and mirroring instances.
This is useful for the kind of clean hard-surface CAD work where a subtle curve transition makes a model look professional. A focused exercise will tell you more than a long feature-tour video.
What to do: In a throwaway Plasticity file, draw two curves with an awkward join, then compare the four continuity modes. Inspect the silhouette from different angles and keep a screenshot of the setting that creates the smoothest transition.
Before you go further: These are 26.1 features, not a claim that an unreleased 26.2 build is available. Save the real project before experimenting, and do not change the production Stream Deck mapping for a five-minute test.
