constraints.HorizontalConstraint
constraints.HorizontalConstraint(point1, point2, *, weight=1.0)Constraint that forces two sketch points onto a horizontal line.
This constraint enforces: y1 = y2 (in sketch-plane coordinates).
Reduces DOF by 1 (one scalar equation).
Parameters
| Name | Type | Description | Default |
|---|---|---|---|
| point1 | Vector2 | First sketch point (Vector2 parameter) | required |
| point2 | Vector2 | Second sketch point (Vector2 parameter) | required |
Example
p1 = Vector2([0, 0], free=True, name='p1')
p2 = Vector2([2, 1], free=True, name='p2')
constraint = HorizontalConstraint(p1, p2)Methods
| Name | Description |
|---|---|
| compute_residual | Compute horizontal constraint residual: y1 - y2. |
| dof_reduction | Horizontal constraint adds 1 scalar equation. |
| get_parameters | Return both points involved in the horizontal constraint. |
compute_residual
constraints.HorizontalConstraint.compute_residual(param_values)Compute horizontal constraint residual: y1 - y2.
