|||
Pentru a aplica constrângerea de unghi, trebuie urmați următorii pași: |
|||
* Selectați una, două sau trei entități în schiță. Modul va fi ales în funcție de selecție. |
|||
* Invocați constrângerea făcând clic pe pictograma de pe bara de instrumente sau selectând elementul din meniu sau utilizând comanda rapidă de la tastatură. Se afișează o fereastră de dialog contextual pentru editarea referinței. |
|||
* Modificați unghiul, dacă este necesar. Unghiul poate fi introdus ca o expresie care va fi evaluată și rezultatul va fi stocat. Faceți clic pe OK. |
|||

As with any datum constraint, it is possible to change the angle value later by double-clicking the constraint in constraint list or 3d view. Entering a negative value will cause the angle direction to flip. |

In this mode, angle between two curves is constrained at the point of their intersection. The intersection point can be on curves' extensions. The point should be specified explicitly, since curves typically intersect in more than one point. |
|||
<div class="mw-translate-fuzzy"> |
|||
For the constraint to work correctly, the point must be on both curves. So, as the constraint is invoked, the point will be automatically constrained onto both curves ([[Sketcher helper constraint|helper constraints]] will be added, if necessary), and the angle between curves will be constrained at the point. These [[Sketcher helper constraint|helper constraints]] are plain regular constraints. They can be added manually, or deleted. There are no helper constraints on the example picture above, because the point selected is already the intersection of curves. |

The angle between the two edges at a given point is fixed. The point can be any point, e.g. the center of a circle, the endpoint of an edge, or the origin, it can belong to either or both edges, and it can also be a [[Sketcher_CreatePoint|Point object]]. If required [[Sketcher_ConstrainPointOnObject|Point on object constraint(s)]] are added to ensure the point lies on both (extended) edges.

Description
Descriere
Constrângerea de unghi este o datum constraint având ca scop fixarea unghiurilor unei schițe. Este capabilă să definească pantele liniilor individuale, unghiurile dintre linii, unghiurile de intersecții ale curbelor și deschiderile unghiulare ale arcurilor circulare.
Cum se folosește
Sunt patru căi diferite pentru ca această constrângere să fie aplicată:
- Liniilor individuale
- între linii
- asupra interesecțiilor curbelor
- Arcurilor de cercuri
See also: Drawing aids.
Continue mode
- Make sure there is no selection.
- There are several ways to invoke the tool:
- introduced in version 1.0: If the Dimensioning constraints preference is set to
Single tool
(default): press the down arrow to the right of the button and select the Constrain angle option from the dropdown. - If this preference has a different value (and in version 0.21 and below): press the Constrain angle button.
- Select the Sketch → Sketcher constraints → Constrain angle option from the menu.
- introduced in version 1.0: Right-click in the 3D view and select the Dimension → Constrain angle option from the context menu.
- Use the keyboard shortcut: K then A.
- introduced in version 1.0: If the Dimensioning constraints preference is set to
- The cursor changes to a cross with the tool icon.
- Do one of the following:
- Select two lines.
- Select a point and two edges (in that order).
- Select an edge, a point and an edge (idem).
- If a driving dimensional constraint is created, depending on the preferences, a dialog opens to edit its value. A negative value will reverse the angle direction.
- An Angle constraint is added. If a point and two edges have been selected, up to two Point to object constraints can also be added. See Examples.
- Optionally keep creating constraints.
- To finish, right-click or press Esc, or start another geometry or constraint creation tool.
Run-once mode
- Do one of the following:
- Select a single line.
- Select a single circular arc.
- Select two lines.
- Select a point and two edges (in any order).
- Invoke the tool as explained above.
- Optionally edit the constraint value.
- An Angle constraint is added. If a point and two edges have been selected, up to two Point on object constraints can also be added. See Examples.
Examples
Single line
Constrângerea stabilește unghiul polar al direcției liniei. Este unghiul dintre linie și axa X a schiței.
Single circular arc
In acest mod, constrângerea fixată unghiulară a unui arc circular.
Between two lines
În acest mod, constrângerea stabilește unghiul dintre două linii. Nu este necesar ca liniile să se intersecteze.
Between two edges at point
The angle between the two edges at a given point is fixed. The point can be any point, e.g. the center of a circle, the endpoint of an edge, or the origin, it can belong to either or both edges, and it can also be a Point object. If required Point on object constraint(s) are added to ensure the point lies on both (extended) edges. These additional constraints are called helper constraints.
Script
Constrângerea Unghiulară poate fi creată cu macros și de la consola Python console utilizând următoarele:
# line slope angle
Sketch.addConstraint(Sketcher.Constraint('Angle',iline,angle))
# angular span of arc
Sketch.addConstraint(Sketcher.Constraint('Angle',iarc,angle))
# angle between lines
Sketch.addConstraint(Sketcher.Constraint('Angle',iline1,pointpos1,iline2,pointpos2,angle))
# angle-via-point (no helper constraints are added automatically when from python)
Sketch.addConstraint(Sketcher.Constraint('AngleViaPoint',icurve1,icurve2,geoidpoint,pointpos,angle))
unde:
- Sketch este un obiect tip schiță
- iline, iline1, iline2 sunt numere întregi specificând liniile printr-un număr ordinal in Sketch.
- pointpos1, pointpos2 should be 1 for start point and 2 for end point. The choice of endpoints allows to set internal angle (or external), and it affects how the constraint is drawn on the screen.
- geoidpoint and pointpos in AngleViaPoint are the indexes specifying the point of intersection.
- angle este valoarea unghiului în radiani. Unghiul este contorizat între vectorii tangenți în sens antiorar. Vectorii tangenți indică de la început până la capăt liniile (sau invers, dacă punctul final este indicat liniar) și în sens antiorar pentru cercuri, arce și elipse. Cantitatea este, de asemenea, acceptată ca un unghi (de exempluApp.Units.Quantity('45 deg'))
The Sketcher scripting page explains the values which can be used for iline

, iline2
