The 3D sketch environment is available in part files only (.ipt).
Use 2D and 3D sketch environments to create 3D features
Create geometry at any point in 3D space using a 3D sketch. A 3D sketch does not use a sketch plane. By comparison, a 2D sketch is created on a single flat plane such as XY.
Use a 2D sketch to create planar geometry for features like extrude and revolve, and to create 2D cross sections for 3D lofts and sweeps.
Use a 3D sketch to create paths for wiring, tubing, sweeps, and lofts. You can also use a 3D sketch to create surface edges.
Tips for working with 3D sketches
- Consider placing work points or sketch points to locate the 3D sketch pick points.
- Create the 2D cross section in a 2D sketch and then create the centerline or sweep path in a 3D sketch.
- Click anywhere in 3D space to place a point.
- Click anywhere in 3D space to place a line or spline segment.
- Right-click a point and use 3D move/Rotate to position the sketch geometry.
- Use a Coincident Constraint to attach 3D curve endpoints.
- Turn off the visibility of dimensions or sketches for clarity.
- Use the Construction command to change reference geometry to construction geometry.
