General information about a sketch |

Sketch is a 3D modeling object created using drafting and graphic editor tools. Sketches are used for different purposes, for example:
•setting the section shape of the solid or surface,
•setting the path of the section movement,
•setting the position of the array instances and others.
The sketch is constructed on a plane defined by a flat object of the model or a curve. More about the placement of the sketch...
A sketch may contain one or several chains of objects — sketch contours. The contours may be closed or open. They may be intersecting. If closed regions are formed in this case, then these areas can be specified as source elements for various designs. Self-intersection of contours is not allowed.
The same sketch can be used in several different operations. For some operations you can specify both the entire sketch and an closed area in the sketch, limited by a contour or several intersecting contours. For more details on using sketches in operations...
Working with a sketch is carried out in a special mode with the model — sketch mode.
By default, the parametric mode is enabled in each new sketch (in the model). parametric mode). To learn about parametric mode setup in a sketch, see the section Parameterization.
In the parametric mode, parametric constraints are applied to the sketch objects automatically. If required, you can disable the parametric mode, but this method of operation is not recommended.

Diagnostics of a parametrized sketch
If the model already contains objects (faces, edges, vertices, etc.), they can be used when creating a sketch. You can project objects into a sketch or perform object snapping. In the latter case projections of objects in the sketch will be created automatically. More details on using model objects when building a sketch...
