PerpendicularDirSelector()

The PerpendicularDirSelector class is a DirectionSelector implementation that allows users to select a direction perpendicular to a specified reference direction.

Constructor

PerpendicularDirSelector(reference_dir)

• reference_dir: The reference direction to which the selected direction will be perpendicular.

Methods

get_directions(prompt)

This method prompts the user to select a direction perpendicular to the reference direction. The prompt string can be specified as an argument.

get_directions(prompt=None)

• prompt: (optional) The prompt string to display to the user.

Returns a list of FreeCAD.Vector objects representing the selected direction(s).

can_reverse()

This method returns True if the selector allows reversing the selected direction, False otherwise.

can_reverse()

Returns a boolean value.

reverse()

This method reverses the selected direction. The method has no effect if can_reverse() returns False.

reverse()

Example usage

import cadquery as cq

# Define a box shape
box = cq.Workplane("XY").box(1, 1, 1)

# Define a reference direction perpendicular to the XY plane
ref_dir = cq.Vector(0, 0, 1)

# Initialize the selector with the reference direction
selector = cq.PerpendicularDirSelector(ref_dir)

# Prompt the user to select a direction perpendicular to the reference direction
dir = selector.get_directions("Select a direction perpendicular to the XY plane")

# Extrude the shape in the selected direction
result = box.extrude(dir)
