Sketcher Constraints
Constraints are used to define lengths, set rules between sketch elements, and to lock the sketch along the vertical and horizontal axes. Some constraints require the Helper constraints

Not associated with numeric data


 * [[Image:Constraint_PointOnPoint.png|32px]] Coincident: Affixes a point onto (coincident with) one or more other points.
 * [[Image:Constraint_PointOnObject.png|32px]] Point On Object: Affixes a point onto another object such as a line, arc, or axis.
 * [[Image:Constraint_Vertical.png|32px]] Vertical: Constrains the selected lines or polyline elements to a true vertical orientation. More than one object can be selected before applying this constraint.
 * [[Image:Constraint_Horizontal.png|32px]] Horizontal: Constrains the selected lines or polyline elements to a true horizontal orientation. More than one object can be selected before applying this constraint.
 * [[Image:Constraint_Parallel.png|32px]] Parallel: Constrains two or more lines parallel to one another.
 * [[Image:Constraint_Perpendicular.png|32px]] Perpendicular: Constrains two lines perpendicular to one another, or constrains a line perpendicular to an arc endpoint.
 * [[Image:Constraint_Tangent.png|32px]] Tangent: Creates a tangent constraint between two selected entities, or a co-linear constraint between two line segments. A line segment does not have to lie directly on an arc or circle to be constrained tangent to that arc or circle.
 * [[Image:Constraint_EqualLength.png|32px]] Equal Length: Constrains two selected entities equal to one another. If used on circles or arcs their radii will be set equal.
 * [[Image:Constraint_Symmetric.png|32px]] Symmetric: Constrains two points symmetrically about a line, or constrains the first two selected points symmetrically about a third selected point.

Associated with numeric data

For these constraints you can use the expressions. The data may be taken from a spreadsheet.


 * [[Image:Sketcher_ConstrainLock.png‎|32px]] Lock: Constrains the selected item by setting vertical and horizontal distances relative to the origin, thereby locking the location of that item. These constraint distances can be edited later.
 * [[Image:Constraint_HorizontalDistance.png‎|32px]] Horizontal Distance: Fixes the horizontal distance between two points or line endpoints. If only one item is selected, the distance is set to the origin.
 * [[Image:Constraint_VerticalDistance.png|32px]] Vertical Distance: Fixes the vertical distance between 2 points or line endpoints. If only one item is selected, the distance is set to the origin.
 * [[Image:Constraint_Length.png|32px]] Length: Defines the distance of a selected line by constraining its length, or defines the distance between two points by constraining the distance between them.
 * [[Image:Constraint_Radius.png|32px]] Radius: Defines the radius of a selected arc or circle by constraining the radius.
