How to transform global axis into local using python in cadwork?

[lucas-ita]

Hi,
Could someone please share a code snippet utilizing the apply_transformation_coordinate(elements, old_point, old_xl, old_yl, new_point, new_xl, new_yl) method? To aid our understanding, let's consider a practical example involving an inclined beam in Cadwork. Let's envision placing the beam in a scene and, subsequently, using the mentioned method to transform the global axis into local coordinates. The expected outcome is that the beam no longer remains inclined.

you could do something like this

from typing import List

import cadwork
import element_controller as ec
import geometry_controller as gc


def get_element_orientation_and_position(element_id: int):
    point1 = gc.get_p1(element_id)
    x_direction = gc.get_xl(element_id)
    y_direction = gc.get_yl(element_id)
    return point1, x_direction, y_direction


def transform_element(element_id: int, point1_new: cadwork.point_3d, x_direction_new: cadwork.point_3d,
                      y_direction_new: cadwork.point_3d):
    point1_old, x_direction_old, y_direction_old = get_element_orientation_and_position(element_id)
    ec.apply_transformation_coordinate([element_id],
                                       point1_old,
                                       x_direction_old,
                                       y_direction_old,
                                       point1_new,
                                       x_direction_new,
                                       y_direction_new)


if __name__ == '__main__':
    element_ids: List[int] = ec.get_user_element_ids()

    x_direction_new = cadwork.point_3d(1., 0., 0.)
    y_direction_new = cadwork.point_3d(0., 1., 0.)

    for element_id in element_ids:
        point1_new = gc.get_p1(element_id) # or set your preferred position
        transform_element(element_id, point1_new, x_direction_new, y_direction_new)
