Copy an INSERT entity from one dxf file to another dxf file using ezdxf?

Question

I have a dxf file blocks.dxf containing multiple block entities. I have another dxf file in.dxf into which I need to import the block entities of the previous dxf file blocks.dxf .

How do I copy the block entities from one file to another using ezdxf Python module so that the copied blocks can be inserted anywhere in the in.dxf file?

Answer 1

For people still looking for an answer on how to copy block definitions:

#generate list of blocks to import
list_of_blocks = df_uni_temp[mask].RefNo2.tolist()

doc_blocks = ezdxf.readfile('blocks.dxf')
doc = ezdxf.readfile('in.dxf')
importer = Importer(doc_blocks, doc)
#iterate through list of blocks
for b in list_of_blocks :
    print(b)
    importer.import_block(b)
importer.finalize()
