[libredwg] Entities in Paperspace are appearing in Modelspace.

For some reason, entities which shoud appear in Paperspace BLOCK areas
are in the ENTITIES area, which means that they are rendered in

How do I find the value of the 330 DXF code of an entity?

The drawing has 3 Paperspace tabs in addition to Modelspace.

*Paper_Space1 and *Paper_Space2 both have entries in the BLOCKS
SECTION and the entities which belong to these spaces appear before
the ENDBLK in each block portion.

These entities display which Paperspace BLOCK_HEASER they belong to
using the structure

So far so good.

However, *Paper_Space does not have a BLOCK entry in the BLOCKS
SECTION and they are simply listed in the ENTITIES SECTION, albeit
with a 330 DXF Code which references the *Paper_Space BLOCK_HEADER.
So dwg.object[index]->tio.entity->ownerhandle is zero and
dwg.object[index]->tio.entity->ownerhandle->handleref.value; is

Hence these entities (which includes VIEWPORT entities) appear in
model space when they should appear in *Paper_Space.

If I examine the drawing converted to DXF, the 330 DXF code correctly
identifies the BLOCK_HEADER handle of the *Paper_Space block.

How do I extract the 330 code?

Many Thanks,
