Create Enumeration using RTC 6.0.3
Accepted answer
The question does not provide any steps and seems to be disconnected from what the tools support and how a bit.
Here my summary for the topic.
- You can create enumerations in the place you mention.
- Then you have to create a custom attribute and select a type. The type can be an enumeration or an enumeration list.
- Enumeration allows to select one value, Enumeration List allows to select several values.
- Plan views do not support attribute types of enumeration list.
