how to have access block attributes
how to have access block attributes
hello
i want to have access to block attribute.
for now, i know how to get the name, but i haven't found yet how to get le 3dpoints of all the attributes of a block (line, arc ...).
could you please tell me wich functions i could use to have access to these attributes?
i have access to the "oddbentityptr" for each attribute, but i don't know how to go further (access to points ...) of each of these attributes.
thanks a lot

if you mean attributes attached to block reference you get access to them via iterator returned from oddbblockreference::attributeiterator().
if you mean attribute definitions they are among entities inside the blocktablerecord (block definition).
you can get pointer to attribute or attribute definition having pointer to oddbobject or oddbentity using:
code:
oddbobjectptr pobj;
oddbattributeptr pattr = oddbattribute::cast(pobj);
or
oddbattributeptr = pobj;
the difference between these 2 methods is:
if pobj points to an object which is not oddbattribute or its inheritor using the first method you get null pointer.
using the second method exception "enotthat kindofclass" will be thrown.
having pointer to oddbattribute you can call methods of oddbattribute class (dbattribute.h)
