DrawOrder

[colander]

Dear All,

I'm trying to put some object behind some others.
There is a line drawn from the centre of a filled circle,
and I like it to show when it leaves the circle.

I Have this:

AcDbBlockTableRecord *block;
acdbOpenObject(block, getBlock(ACDB_MODEL_SPACE), AcDb::kForRead);
AcDbSortentsTable *drawOrder;
block->getSortentsTable(drawOrder, AcDb::kForWrite, Adesk::kTrue);
drawOrder->moveToBottom(lines);
drawOrder->close();
block->close();


Lines is an Array containing all the object ID's
of the lines drawn. And getBlock does what
it says....

Off cousre the lines are still above the circles....

Help?

Thanks,
Bas

For some extra info
the drawOrder->moveToBottom(lines); line
returns eWasOpenForWrite.....
(I changed kForWrite to kForRead, doesn't matter at all....

Just guessing here but are the lines open for write?

[colander]

Nope 😞

It's not that simple.....

Okay, Still don't get it, but......

When I put this code in the beginning of my little programme;
AcDbBlockTableRecord *block;
acdbOpenObject(block, getBlock(ACDB_MODEL_SPACE), AcDb::kForRead);
AcDbSortentsTable *drawOrder;
block->getSortentsTable(drawOrder, AcDb::kForWrite, Adesk::kTrue);
drawOrder->close();
block->close();


It works.....

Anybody any clue why this is needed

I also had the problem described above.

The model space is not allowed to be open for write during the changes you make to the AcDbSortentsTable. So either you close the model space before, or you downgrade open it.
