Carefully select the blue z-axis to set the line, making sure it automatically add a vertical constraint.įor the third line, we’ll want to head back toward the center, while following the green y-axis. The cursor should snap to the z-axis when close. We can start to sketch the height of the table by moving our mouse cursor to the blue z-axis. Fusion 360 will automatically add a “horizontal/vertical” constraint for us. Type out 45cm for the length and then click where the line snaps into the Y-axis. Similar to a 2D sketch, we will drag our mouse cursor along the green Y-axis. This will help us sketch in 3-dimensions.Īt this point, we can start the line by setting the first point at the origin point. Select the line feature in the toolbar or hit the keyboard shortcut “L.” Select the “Home” position next to the ViewCube. Select the 3D Sketch checkbox in the Sketch Palette to turn it on. We’ll click this plane to start by drawing the bottom of the table as if it were sitting on the ground. Start the sketch by selecting the XY origin plane. However, we can make the table much faster using 3D sketches. This table design could theoretically use 2D Sketches. I happened to come across this “ C Side Table” on Amazon and thought it was the perfect 3D Sketch beginner project.
In short, use a 3D sketch to create a path for tubing, sweeps, lofts, or surface edges, when the design continues to multiple planes.
That may have you wondering, “When should I use a 3D Sketch?” There’s no question that 3D sketches come with extra complexity. Knowing when to use a 3D sketch instead of a 2D sketch can make all the difference.
Sketch dimensions and constraints can sometimes be harder to update and manage with 3D sketches – making the concept of design intent harder. You’ll often have several different sketch features that make up a design.Ĭontrary, 3D sketches will be one single sketch feature in the timeline. It’s important to note that 2D sketches also exists as an individual Sketch feature in the parametric timeline. With a 3D sketch, Fusion 360 removes the planar restriction allowing you to create sketch geometry anywhere in 3D space. However, the selected plane restricts sketch geometry to that plane. You can create a new 2D sketch on each of the following:Ī 2D sketch plane can originate anywhere in 3D space. In a 2D Sketch, we constrain sketch geometry to the plane used to create the sketch. Guidelines then appear to help you understand where the sketch is going to be in 3D space. Moving from one sketch plane to another is as easy as moving your mouse cursor in the direction you want to sketch. With these enhancements, you now immediately see origin axes, planes, and rotational manipulators to help create your 3D sketch.
Sketch Constraints Supported by 3D SketchģD Sketches also support the use of the following sketch constraints: This Fusion 360 update brings new 3D sketching behavior to the following sketch features:
