# Creating an L-shaped pipe programmatically in Blender
# involves several steps, including mesh editing,
# vertex beveling, converting the mesh to a curve,
# and then adjusting the curve's properties to give it
# depth and resolution before finally converting it back
# to a mesh.
# The following function encapsulates this process:import bpy

def create_l_shaped_pipe(plane_size=2, bevel_segments=8, curve_depth=0.5, curve_resolution=4):
    """
    Creates an L-shaped pipe from a plane by deleting two adjacent edges, beveling a vertex,
    converting to a curve, and adding depth and resolution to the curve.

    Parameters:
    - plane_size: The size of the initial plane.
    - bevel_segments: Number of segments in the bevel.
    - curve_depth: The depth of the curve to represent the pipe's thickness.
    - curve_resolution: The resolution of the curve.
