At the moment you have only very basic control in the align tool and you cant realy change the behavior to your needs. an more alias like behavior would be nice CV Distribution Types This setting controls how the Control Vertices (CVs) are moved to reach the required continuity (G1 Tangency or G2 Curvature). "Next" (Minimal Deviation): The Goal: Preserve the existing surface shape of the aligned surface as much as possible. Mechanism: CVs move the smallest distance necessary to achieve the target continuity. Result: Minimal change to your original surface design; only the area near the edge is modified. "Equal" (Uniform Distribution): The Goal: Create a clean, mathematically "pretty" hull.Mechanism: CVs are redistributed at even intervals along the surface flow.Result: The internal structure becomes very clean, but the overall shape of the surface can change significantly to allow for this uniform spacing. Surface Types / Alignment Modes These modes define what the tool uses as a reference for the G1 and G2 alignment. Mode 1: Colinear Directional (Structure-to-Structure) Logic: The CV rows of your surface align directly with the CV rows (the "hulls") of the target surface. Behavior: It creates a perfect flow between the two surfaces' internal grids .Best for: Untrimmed, four-sided surfaces where the topology of both parts matches. Mode 2: Trimmed Surface (Edge-to-Boundary)Logic: The tool ignores the target surface's internal CV layout. Instead, it aligns your surface's edge and continuity (G1/G2) directly to the interpolated points of the cut (trimmed) edge. Behavior: The CVs of your surface will not follow the direction or flow of the target surface's original CVs. They focus purely on the geometry of the trim line. Best for: Aligning a new surface to a hole or a diagonal cut in an existing model. Mode 3: Projected / Span-free (Simplified Edge-to-Boundary) Logic: The tool projects the target edge (usually via View Normal) and creates an internal, simplified, "span-free" version of that edge. Behavior: Like Mode 2, it aligns your surface to this projection rather than the target's CV structure. This ignores the target's original CV flow to ensure your new surface doesn't inherit unnecessary complexity or "noise" from a messy trim edge. Best for: Achieving a very smooth, simple alignment even when the target edge is topologically complex or has too many spans. Keep up the godlike work
