from build123d import Box, Cylinder, export_brep, export_step
from OCP.BRepTools import BRepTools

obj = Box(2, 2, 1) - Cylinder(0.5, 2)
BRepTools.Write_s(obj.wrapped, sys.stdout.buffer)

python script.py | f3d - --output=- | display

☁️ Added support for many point cloud formats

View your point clouds easily easilly, .las, .laz and many more.
