Is there one way to set Block's base_point later after created

[hom]

Hi, I want to set Block's base_point attribute after it is created, such as doc.blocks.new(name="BLOCKNAME") or doc.new_anonymous_block()

blk = doc.new_anonymous_block()

I try to use ways below, and always return AttributeError: can't set attribute 'base_point error message.

blk.base_point = Vec3(-10, -10, 0)

and

blk.__setattr__("base_point", Vec3(-10, -10, 0))

and

setattr(blk, "base_point", Vec3(-10, -10, 0))

and some other ways

This is my source code:

import ezdxf
from ezdxf.math import Vec3
from ezdxf.enums import TextEntityAlignment
from ezdxf.tools.text_size import text_size

doc = ezdxf.new(dxfversion="R2018", setup=["linetypes"])
msp = doc.modelspace()
blk = doc.blocks.new_anonymous_block()
text = blk.add_text(text="0.1", dxfattribs={"height": 4, "width": 1, }).set_placement((10, 10), align=TextEntityAlignment.MIDDLE)
blk.__setattr__("base_point", Vec3((-10, -10, 0)))
msp.add_blockref(blk.name, insert=(0, 0))

doc.saveas("output/set_block_base_point.dxf")

Anyone here can help me? Thanks very much:)

The method new_anonymous_block() has an argument base_point to define the block base point.

If that's not good enough, the method returns a BlockLayout instance that has an attribute block which is a Block instance of the related BLOCK entity, which represents that BlockLayout. The Block entity contains the desired DXF attribute base_point.

blk.block.dxf.base_point = Vec3(-10, -10, 0)

Yeah, thanks very much, it's amazing.

The error is what I change the base_point attribute in returned new_anonymous_block() directly, which try to set base_point to BlockLayout entity, so it set failed. And I need to get the Block entity first when changing base_point later. Got it!!

Thanks @mozman again:)
