Sketching with Constraints

You can choose constraint-based sketching to reduce the degrees of freedom (place constraints) on the drawing objects in 2D drawings and designs. Adding constraints restricts the type and range of movement of the objects, and links objects such that certain editing tasks on one drawing object will cause linked objects to be modified. Use tools in the Constraints group in the Sketch tab to add constraints to sketches.

Certain sketching tools included rudimentary tangency and coincident constraints (enabled with the Maintain Connectivity option), but these may be overridden during drawing editing. The tools in the Constraints group offer additional types of constraints which can be applied to any of the standard drawing objects (line, circle, arc, and so on) and are more robust.

To use constraint-based sketching, ensure that Enable constraint based sketching is selected in the Advanced options in the SpaceClaim Options.
