كيفية إنشاء رسم DXF جديد عبر مكتبة Python؟

import ezdxf
from ezdxf import colors
from ezdxf.enums import TextEntityAlignment

# Create a new DXF document.
doc = ezdxf.new(dxfversion="R2010")

# Create new table entries (layers, linetypes, text styles, ...).
doc.layers.add("TEXTLAYER", color=colors.RED)

# DXF entities (LINE, TEXT, ...) reside in a layout (modelspace, 
# paperspace layout or block definition).  
msp = doc.modelspace()

# Add entities to a layout by factory methods: layout.add_...() 
msp.add_line((0, 0), (10, 0), dxfattribs={"color": colors.YELLOW})
msp.add_text(
    "Test", 
    dxfattribs={
        "layer": "TEXTLAYER"
    }).set_placement((0, 0.2), align=TextEntityAlignment.CENTER)

# Save the DXF document.
doc.saveas("test.dxf")

import ezdxf
from ezdxf.enums import TextEntityAlignment

# The TEXT entity is a DXF primitive and is supported in all DXF versions.
# The argument setup=True creates standard linetypes and text styles in the
# new DXF document.
doc = ezdxf.new("R12", setup=True)
msp = doc.modelspace()

# Use method set_placement() to define the TEXT alignment, because the
# relations between the DXF attributes 'halign', 'valign', 'insert' and
# 'align_point' are tricky.
msp.add_text("A Simple Text").set_placement(
    (2, 3),
    align=TextEntityAlignment.MIDDLE_RIGHT
)

# Using a predefined text style:
msp.add_text(
    "Text Style Example: Liberation Serif",
    height=0.35,
    dxfattribs={"style": "LiberationSerif"}
).set_placement((2, 6), align=TextEntityAlignment.LEFT)

doc.saveas("simple_text.dxf")
