Import Options

The Creo reader uses the ct_reader.ini file.
@AttributesAsMetadata
Value Description
on

Import all generic attributes (global and related to single entities) as metadata.
off Do not import attributes related to single entities. Only import global attributes.
%attribute1%attribute2%attribute3

Import specified generic attributes as metadata.

The attribute names are listed, separated by a character that you choose, and inserted as the first element of the string. The example uses '%' as a separator. You can choose another character as a separator, in case one of the listed attribute names contains '%'. HyperMesh will recognize it as it is the first character of the string.

off Use the conversion functions provided by third-party.
@BodyIdAsMetadata
Value Description
