[cgma-dev] RefGroup question

[David Thompson]

Hi Jane,

Sorry for the slow reply. Thanks for finding the problem! I was unaware of the difference between

	auto_flag(CUBIT_TRUE);

and

	set_all_auto_read_flags(true);
	set_all_auto_write_flags(true);
	set_all_auto_actuate_flags(true);

Once the repository is migrated to bitbucket, I'll submit a pull request with some more documentation.

	Thanks again,
	David

Starting at line 178, you will see that if the flag 'act_att' is set to true (it is initialized to true at line 136), then the attribute_manager is set to automatically read and apply the attributes upon reading a file.
