Description
Descriere
Constrain distance constrânge lungimea unei linii, distanța perpendiculară dintre un punct și o linie sau distanța dintre două puncte pentru a avea o valoare specificată.
Cum se folosește
See also: Drawing aids.
Continue mode
Run-once mode
- Do one of the following:
- Select a single line.
- Select two points.
- Select a point and a line (in any order).
- Select the edges of two circles or arcs.
- Select the edge of a circle or arc and a line (idem).
- introduced in version 1.0: Select the edge of a single arc.
- Invoke the tool as explained above.
- Optionally edit the constraint value.
- A constraint is added.
Notes
Aluzie
Dacă este cazul, vă rugăm să luați în considerare utilizarea constrîngerii Horizontal distance sau în loc a constrângerii Vertical distance . Aceste constrângeri sunt mai robuste și mai rapide pentru a calcula decât constrângerea de lungime documentată aici.
Scripting
Distance from origin:
Sketch.addConstraint(Sketcher.Constraint('Distance', Edge, PointOfEdge, -1, 1, App.Units.Quantity('123.0 mm')))
Distance between two vertices:
Sketch.addConstraint(Sketcher.Constraint('Distance', Edge1, PointOfEdge1, Edge2, PointOfEdge2, App.Units.Quantity('123.0 mm')))
Length of line (the GUI allows selecting the edge itself, but it is just a shorthand for using the two extremities of the same line):
Sketch.addConstraint(Sketcher.Constraint('Distance', Line, 1, Line, 2, App.Units.Quantity('123.0 mm')))
Distance from point (Edge, PointOfEdge
) to perpendicular point on line (Line
):
Sketch.addConstraint(Sketcher.Constraint('Distance', Edge, PointOfEdge, Line, 0, App.Units.Quantity('123.0 mm')))
Distance between the edges of two circles:
Sketch.addConstraint(Sketcher.Constraint('Distance', Circle1, 0, Circle2, 0, App.Units.Quantity('123.0 mm')))
The Sketcher scripting page explains the values which can be used for Edge
, Edge1
, Edge2
, PointOfEdge
, PointOfEdge1
, PointOfEdge2
, Line
, Circle1
and Circle2
, and contains further examples on how to create constraints from Python scripts.
