Ycad - Java CAD library

Hi, YCad team.

I have a problem here. I am using the YCad Java
Library, but when I am importing some DXF files, I
find an entity called AECC_POINT. I don´t know if it
is really an entity. I just know that YCad unknow this
type of entity, I guess.
I need to know, how can I process this entity? Or,
what is AECC_POINT? Can I to go inside this group and
take the entities that I find there? How can I do that?
Please, I need your help.

Thanks.
