To get the names:What do you mean exactly? could you send me a few lines of code?
Start digging in the extension dictionary of the model space block.
To rename:
You can probably just call the -Parameters command.
> Extension dictionary of the model space object
> BDM_DATABASE dictionary
> BDMDBCONSTRAINTMANAGER entity
An entity list of a BDMDBCONSTRAINTMANAGER entity does not provide any further leads (the gc 330 ename points to the parent dictionary):(
(-1 . <Entity name: 53cc03f0>)
(0 . "BDMDBCONSTRAINTMANAGER")
(5 . "D3")
(102 . "{ACAD_REACTORS")
(330 . <Entity name: 53cc0c70>)
(102 . "}")
(330 . <Entity name: 53cc0c70>)
)
You can try sending in a Support Request.
