 Hi.

I would like to have a function like look "laydel" command.

I use layer name (NombreCapa) as parameter but my method in some cases is very slow.

I don´t check if some entity can´t be delete, because all entities that I use within that layer will be circles.

Are there any methods faster than mine?

Thanks in advance.

GetEntitiesOnLayer() is a method of the same blog:

In this case, it´s for change all layer from one layer to other layer.

Yes, Before you delete a layer, you should decide what to do with those objects that draw on this layer? It is not that those objects could or could not be delete, but that when a layer has objects on it,  just deleting this layer may cause problems. 

if you would like to delete the objects as well, i suggest you just delete all the objects that within this layer and use Purge to delete the layer, i think this way sounds better.
