How to insert coordinates, a rotation and different axis scales (x,y,z) for a block imported ?

[remysompayrac]

Hello again, I have a question I tried my best to fix on my own but didn't succeed.
My wish is to insert coordinates in the block references of a block I imported in my script, along with a rotation angle and (if possible), modify the xscale of the block.
Yet, I couldn't find a proper solution. The script didn't show any errors but no change was detected after testing.
Here is a piece of my code.

    sdoc = ezdxf.readfile(f'symboles_autocad/F_{largeur}.dxf')
    tdoc = ezdxf.new()

    importer.import_paperspace_layouts()
    tblock = tdoc.blocks.new('SOURCE_ENTS')
    ents = sdoc.modelspace().query('CIRCLE LINE')
    importer.import_entities(ents, tblock)
    PORTE = tdoc.blocks.new(name='PORTE')
    importer.finalize()

    # rotation du bloc

    angle_rot = np.arctan(coeff_dir)
    angle_rot = angle_rot * 180/np.pi # attention, prendre en compte le sens direct
                     
    msp.add_blockref('PORTE', (x,y), dxfattribs={
        'xscale': 1,
        'yscale': 1,
        'rotation': angle_rot   
    })
    
    tdoc.saveas(f'data_save/FENETRE_{largeur}.dxf')

Is msp the modelspace of the target doc?

The simple question was: What do expect to see when you insert an EMPTY (=no content) block?

[remysompayrac]

It is not an EMPTY block because when I save the document, I can read the dxf with the block inside.
It reads the dxf of a block I made on Autocad.
The objective of this code is to import this block and create a function to insert it into the dxf with specific features like coordinates (x,y), the scales, and a rotation angle.

The only thing that doesn't show is the change in the xscale, the rotation of the block and the coordinates of the block which don't apply.That is my only question and it has always been from the beginning. How to add these attributes to the block I just imported ?

Maybe I misunderstood your statement but I have to say it's quite unclear.
When you say EMPTY block, do you talk about "msp" or "PORTE"?

[mozman]

You create a new block "PORTE" at (1), its empty. You add a block reference of "PORTE" at (2) it's still empty!

[mozman]

Why are you importing the DXF drawing in the first place, just use the source document as a template, add your stuff and save a new DXF document.

1. you import the modelspace
2. you import all paperspace layouts
3. you import some entities from the modelspace a second time
4. you do NOT import any block definitions

Thank you for all your explanations, I understand and I'm going to code it :)
