The definition name of a symbol should be unique in the database. It is recommended that the namespace of symbol definition class should be specified as follows:
<CompanyName>.SP3D.Content.<Specialization>.
For example, Ingr.SP3D.Content.Support
We also recommended that if a delivered symbol definition must be changed to meet a specific requirement, its namespace/symbol definition class name be changed so that the identity of the modified symbol is different (unique) from the one delivered in the software.
