|Sketcher Constraint Vertical|
The Horizontal Constraint forces a selected line or lines in the sketch to be parallel to the horizontal axis of the sketch.
Select a line in the sketch by clicking on it.
The line turns dark green.
Apply the Horizontal Constraint by clicking on thein the Sketcher Constraints toolbar or by selecting the Constrain horizontally menu item in the Sketcher constraints sub menu of the Sketcher menu item in the Sketcher work bench (or the Part Design menu item of the Part Design work bench). The selected line is constrained to be parallel to the horizontal axis of the sketch.
Multiple lines may be selected
and then applying the constraint as described above, they are constrained to be parallel to the sketch horizontal axis.
The Sketcher scripting page explains the values which can be used for
Line and contains further examples on how to create constraints from Python scripts.
