Internal Structure¶

Do not change this structures, this is just an information for experienced developers!

The BLOCK_RECORD is the owner of all the entities in a layout and stores them in an EntitySpace object (BlockRecord.entity_space). For each layout exist a BLOCK definition in the BLOCKS section, a reference to the Block entity is stored in BlockRecord.block.

Modelspace and Paperspace layouts require an additional DXFLayout object in the OBJECTS section.
