Constraint in the unigraphics

Constraint very important role in the depiction for the precision to results.Constraint that allows us to precisely control the objects in a sketch.
There are two types of constraint- Dimensional Constraintsi and geometric constraints.Dimensional ConstraintsDimensional Constraints, specify the size of the sketch object (suchas the radius of arc) or the relationship between two objects, such asthe distance between two points.A geometric constraint characteristic geometric shape of the objectsketch or sketches of the type of relationship between two or moreobjects.Constraints include:1. Tangent2. Vertical3. Coincident4. Horizontal5. PerpendicularWe can see all the geometric constraints by turning on all constraints.Options on the toolbar constraint Sketch provides a way to apply,remove, and edit a constraint.
To use the constraint step we have to do:Once we make a sketch drawing, click the sign / icon constrainClick the sketch to be in the constraintSelect the desired constraintClick OK
