![]() ![]() ![]() However, be aware that constrained sketches can lock down features in your design more robustly than you might want early in the design process, so be cautious when adding too many details and constraints into a single sketch at this stage. ![]() Their behavior in complex parametric designs is more predictable. ![]() Constrained sketches cannot move when clicking and dragging with your mouse. They’re useful when you know the precise details of a design and are certain about your design intent. You also can lock things down gradually as you evolve your design. However, referencing unconstrained sketch geometry in downstream designs can cause unpredictable results in complex parametric assemblies.Ī Constrained Sketch contains geometry locked down in place by constraints and dimensions. They’re ideal for when you’re experimenting and want flexibility before committing to your design. In the sketch environment, you can create either unconstrained or constrained sketches:Īn Unconstrained Sketch contains some geometry that is still free to move in space - not locked down by constraints and dimensions. Unconstrained sketches are useful early in the design process. A sketch profile is shaded blue when it is closed, and you can use them to extrude 3D shapes or perform 3D Boolean commands. Open Profile sketch.Ī Closed Profile is a series of connected 2D geometry that does form a closed boundary. You can use open profiles to create surface bodies to extrude thin solid features or to guide some modeling operations like Loft. Let’s look at the two types of sketch profiles open and closed.Īn Open Profile is a series of connected 2D geometry that does not form a closed boundary. If you create a robust sketch profile, you can improve your workflow and minimize potential downstream issues. A sketch is a geometric profile that forms the foundation of 3D geometry in a design in Fusion 360.īefore creating 3D objects in your design, you need to create the underlying sketch profiles that drive the overall shapes of the parametric solid, surface, or T-spline bodies that make up your design.Ī sketch is the backbone of any subsequent parametric modeling. ![]()
