I projected a 2d sketch onto a curved surface using the "Project to 3D Sketch" command. How do I edit and work with the new geometry? I want to break the link between with the 2d sketch but nothing works.
Break links from referenced sketches
You can remove the association between cross-part projected geometry and the parent part.
In the browser, expand the assembly hierarchy, right-click the part you want to make independent, and then select Edit.
Expand the feature containing the reference sketch. Right-click the Reference sketch symbol, and then select Break Link. The Reference sketch symbol is removed from the browser.
The sketch geometry changes from reference geometry to normal geometry. You can add dimensions and constraints as needed.
