## 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:

1. Liniilor individuale
2. între linii
3. asupra interesecțiilor curbelor
4. Arcurilor de cercuri

### Continue mode

1. Make sure there is no selection.
2. 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 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.
3. The cursor changes to a cross with the tool icon.
4. 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).
5. 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.
6. 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.
7. Optionally keep creating constraints.
8. To finish, right-click or press Esc, or start another geometry or constraint creation tool.

### Run-once mode

1. 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).
2. Invoke the tool as explained above.
3. Optionally edit the constraint value.
4. 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

# angular span of arc

# angle between lines

# angle-via-point (no helper constraints are added automatically when from python)
The Sketcher scripting page explains the values which can be used for `iline`, `iline1`, `iline2`, `pointpos1`, `pointpos2`, `geoidpoint` and `pointpos` and contains further examples on how to create constraints from Python scripts.
