I don’t quite understand how construction works using multi-line text in an attribute?

import ezdxf

doc = ezdxf.new(dxfversion="R2018")


block = doc.blocks.new(name="MY_BLOCK")
block.add_attdef("TAG1", (0, 0), "Default Value", height=0.25)
block.add_attdef("TAG2", (0, -1), "Another Default", height=0.25)


msp = doc.modelspace()
insert = msp.add_blockref("MY_BLOCK", insert=(5, 5))
attribs = {
    "TAG1": "Value\n 1",
    "TAG2": "Value\n 2",
}
insert.add_auto_attribs(attribs)
doc.saveas("example.dxf")

Here is an example how to create a multiline ATTDEF:

import ezdxf

doc = ezdxf.new(dxfversion="R2018")
block = doc.blocks.new(name="MY_BLOCK")

# Text, location and height not needed, because copied from MTEXT entity
attdef = block.add_attdef("TAG1")
# Define the multiline attribute as MTEXT entity
mtext = block.add_mtext("Default Value", dxfattribs={"char_height": 0.25})
mtext.set_location((0, 0))
# Set ATTDEF content from MTEXT entity
attdef.set_mtext(mtext)

attdef = block.add_attdef("TAG2", (0, -1))
# reuse existing MTEXT entity
mtext.text = "Another Default"
mtext.set_location((0, -1))
# Set ATTDEF content from MTEXT entity and destroy the MTEXT entity
attdef.embed_mtext(mtext)

# Usage of add_auto_attribs() with multiline ATTDEFs:
msp = doc.modelspace()
insert = msp.add_blockref("MY_BLOCK", insert=(5, 5))
attribs = {
	"TAG1": "TAG1-Line1\nTAG1-Line2",
	"TAG2": "TAG2-Line3\nTAG2-Line4",
}
insert.add_auto_attribs(attribs)
doc.saveas("block_with_multiline_attdef.dxf")

Thank you very much for your efforts. Everything works, I will use it

I rolled back to 1.3.4 and everything works.

Use the global options object to set the path or use a config file. The global variable win_exec_path was removed.
