Troubleshooting Splines and Open Sketch Profiles | Unstuck my Fusion Design

Описание: Unlock the power of sketching and extrusion in Fusion with expert guidance from Phil Eichmiller, Senior QA Engineer on the Autodesk Fusion team and passionate Autodesk Fusion educator. If you’ve ever struggled with extruding a traced sketch, splines acting wonky, or profiles that just won’t close, this detailed walkthrough is for you. Phil starts by addressing a common frustration: tracing around a shape, meticulously constraining lines, and finding yourself unable to extrude the profile.

Next, learn how Fusion handles splines and why their unique “rubber-band” tension is key to smooth curves and successful extrusions. Learn see how point distance impacts spline flexibility: close points sharply turn corners, while spacing out spline points results in smoother lines. Discover why over-constraining or cluttering your spline with too many points causes rough, unpredictable geometry, while minimizing points makes designs flow more naturally.

Phil also demonstrates troubleshooting strategies by zooming into micron-level detail to hunt for open points on your sketch, showing tips like using color cues (black points are connected, white are not) and the “crisscross” trick to isolate gaps. See how resolving even hairline disconnects between endpoints lets Fusion recognize a closed profile, enabling clean, frustration-free extrusion.
