Creating and Using 3D Sketches
3D sketches permit the creation of nonplanar 3D features. 3D sketches are created in single-part files only and comprise geometry located in various XYZ locations or points within the file. Although a 3D sketch may lie in a 2D plane, in most designs that will not be the case. 3D sketches should never be used for creating geometry that could be created within the 2D sketch environment. The 3D sketch tool is accessible only from within the part environment; however, you can project geometry from an assembly into the part to create the 3D sketch.

3D sketches are often used to define paths for modeling ...
