This image shows the Edit Feature panel for the Patch surface tool in Autodesk Fusion. It perfectly captures the exact UI limitation you described: the "Boundary Edges" list box is locked to a fixed vertical height, showing only 4 items at a time regardless of panel resizing.
Why This Happens in FusionFixed UI Containers: The internal list elements use hardcoded size constraints. Expanding the dialog window only scales the outer bounding box and parent container layouts, leaving the child list control unchanged.Input Focus Conflict: The scrollwheel fails because Fusion prioritizes the active 3D viewport canvas. Unless your cursor is pixel-perfectly hovering over the narrow scroll track, scroll inputs are sent to the 3D model camera instead of the list window.
Workarounds to Improve WorkflowCheck "Group Edges": Checking this box combines tangent continuous edges into a single entry. This drastically reduces the number of individual elements in the list and eliminates the need to scroll.Direct Canvas Interaction: Avoid editing continuity conditions (G0/G1/G2) inside the small list window. Instead, click directly on the visual glyphs/arrows that appear over the geometry in your 3D view space.Keyboard Navigation: Click on "Edge 1" and use your keyboard's Down Arrow key to traverse the list seamlessly without using the buggy scrollwheel.
