BlockRecord¶

BLOCK_RECORD (DXF Reference) is the core management structure for BlockLayout and Layout. This is an internal DXF structure managed by ezdxf, package users don’t have to care about it.

Subclass of	`ezdxf.entities.DXFEntity`
DXF type	`'BLOCK_RECORD'`
Factory function	`Drawing.block_records.new()`

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.
