Block references in a particular layer [Solved]

[arun]

Hi,
How do I get the all the Block References from a particular layer.
I tried the

Code: Select all

doc.queryLayerBlockEntities(layerId)

with the following code and I got an error message. Any pointer on the correct usage of this command

Code: Select all

var doc = getDocument();
var layerName = getText();
var layerId = doc.getLayerId(layerName)
var blockEntities = doc.queryLayerBlockEntities(layerId)

Thanks,
Arun

queryLayerBlockEntities returns all entities that are member of a given layer and of a given block (i.e. are part of that block definition).

You could get all entity IDs on a given layer with:

Code: Select all

var entityIds = doc.queryLayerEntities(layerId);

And all block reference IDs with:

Code: Select all

var blockReferenceIds = doc.queryAllBlockReferences();

Then intersect the two (sorted) arrays:

Code: Select all

entityIds.sort();
blockReferenceIds.sort();
var blockReferenceOnLayerIds = Array.intersect(entityIds, blockReferenceIds);

Thanks Andrew. This is good .

arun,

Remark that queryLayerBlockEntities() requires 2 parameters:
