Class: QgsCadUtils

Provides routines for CAD editing.

class qgis.core.QgsCadUtils[source]

Bases: object

class AlignMapPointConstraint[source]

Bases: object

Structure with details of one constraint.

QgsCadUtils.AlignMapPointConstraint(locked: bool = False, relative: bool = False, value: float = 0) Constructor for AlignMapPointConstraint.

QgsCadUtils.AlignMapPointConstraint(a0: QgsCadUtils.AlignMapPointConstraint)

locked: bool
relative: bool
value: float
class AlignMapPointContext[source]

Bases: object

Defines constraints for the QgsCadUtils.alignMapPoint() method.

angleConstraint: AlignMapPointConstraint
cadPoint(self, index: int) → QgsPoint[source]

Returns the recent CAD point at the specified index (in map coordinates).

See also

setCadPoint()

Added in version 3.22.

Parameters:

index (int)

Return type:

QgsPoint

property cadPointList
Return type:

List[QgsPointXY]

cadPoints(self) → List[QgsPoint]

Returns the list of recent CAD points in map coordinates.

These are used to turn relative constraints to absolute. The first point is the most recent point.

setCadPoints()

Added in version 3.22.

Return type:

List[QgsPoint]

commonAngleConstraint: AlignMapPointConstraint
distanceConstraint: AlignMapPointConstraint
lineExtensionConstraint
mConstraint: AlignMapPointConstraint
mapUnitsPerPixel: float
setCadPoint(self, index: int, point: QgsPoint)[source]

Sets the recent CAD point at the specified index to point (in map coordinates).

cadPoint()

Added in version 3.22.

Parameters:
setCadPoints(self, points: Iterable[QgsPoint])[source]

Sets the list of recent CAD points (in map coordinates).

Added in version 3.22.

Parameters:

points (Iterable[QgsPoint])

class AlignMapPointOutput[source]

Bases: object

Structure returned from alignMapPoint() method.

static alignMapPoint(originalMapPoint: QgsPointXY, ctx: QgsCadUtils.AlignMapPointContext) → QgsCadUtils.AlignMapPointOutput[source]

Applies X/Y/angle/distance constraints from the given context to a map point. Returns a structure containing aligned map point, whether the constraints are valid and some extra information.

Parameters:
Return type:

QgsCadUtils.AlignMapPointOutput
