Hello,

I've tested the dwgrewrite and load_dwg examples using the attached empty_v2000.dwg file.

• dwgrewrite works fine.
• load_dwg produces a new file that, when opened in AutoCAD, triggers the warning: "The drawing file requires recovery."

Could you check this behavior and let me know if there's a potential issue?

Thanks!

Tasks:

• GH calc HANDSEED on write (related to need recovery) #1127
• fix the "first entity" handle in the Model_Space BLOCK_HEADER
• add "prev_entity”: [4,0,0,0], "next_entity": [4,0,0,0] to the added entity, change nolinks to 0
