Bridge Vertex Pro — Smart G0/G1/G2 Spline Bridge for Fusion 360

Bridge Vertex Pro — Spline Bridge for Fusion 360

Description

Bridge Vertex Pro is a Fusion 360 add-in that connects any two sketch points with a clean, fully-controlled spline — with independent G0 / G1 / G2 continuity on each side. Stop fighting manual spline handles: pick two points, choose how each end should blend, and get a smooth, production-ready curve in one click.

Key features

• Per-side continuity — set G0 (position), G1 (tangent match) or G2 (curvature match) independently for the start and the end.
• Smart auto-handles — optimal tangent-handle lengths are computed from a circular-arc Bézier model, so the default curve already looks right.
• Tension control — fine-tune tangent (G1) and curvature (G2) strength per side with signed sliders. 0 = automatic.
• Flip direction — reverse the curve direction on either side with a single checkbox when it bows the wrong way.
• Picks up your selection — pre-select two points before launching and they're filled in automatically.
• Lives where you work — adds a button to the Sketch → Modify panel, supports keyboard shortcuts and live preview.
• Sticky settings keep your last configuration during the session.
• Works on Windows and macOS.

Free & supported by you
Bridge Vertex Pro is completely free — the full tool, no feature limits. If it speeds up your workflow and you'd like to back future updates and new Fusion 360 tools, a "Support the Developer ☕" option is available at checkout. Totally optional, hugely appreciated.
