Descriere
Fixează distanța orizontală între 2 puncte sau capetele liniei. Dacă este selectat un singur punct, distanța este setată la originea schiței.
Fixes the horizontal distance between 2 points or line ends. If only one point is selected, the distance is set to the sketch origin.
Folosire
- Selectați unul sau două puncte sau o linie.
- Apăsați butonul
Constrain horizontal distance . - Un dialog contextual deschide pentru a edita sua a confirma valoarea. Apăsați OK pentru a valida.
- Pick one or two points or one line.
- Invoke the tool several ways:
- Press the
Constrain horizontal distance button in the toolbar. - Use the Shift + H keyboard shortcut. (H is for Horizontal)
- Use the Sketch → Sketcher constraints → Constrain horizontal distance from the top menu.
- Press the
- A pop up dialog opens to edit or confirm the value. Press OK to validate.
Note: instrumentul de constrângere poate fi pornit și fără o selecție prealabilă. Pentru a seta distanța de la origine, punctul de origine Sketch trebuie să fie selectat de asemenea. Implicit, comanda va fi în modul continuu pentru a crea noi constrângeri; apăsați butonul drept al mouse-ului sau ESC o dată pentru a părăsi comanda.
Scripting
Distance from origin:
Sketch.addConstraint(Sketcher.Constraint('DistanceX', Edge, PointOfEdge, App.Units.Quantity('123.0 mm')))
Distance between two vertices:
Sketch.addConstraint(Sketcher.Constraint('DistanceX', Edge1, PointOfEdge1, Edge2, PointOfEdge2, App.Units.Quantity('123.0 mm')))
Horizontal span 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('DistanceX', Line, 1, Line, 2, App.Units.Quantity('123.0 mm')))
The Sketcher scripting page explains the values which can be used for Edge1, Edge2, Edge, PointOfEdge1, PointOfEdge2, PointOfEdge and Line, and contains further examples on how to create constraints from Python scripts.
