How can I enable DB field name autogeneration?

[AlexNek]

I have found strange behavior that sometimes table names/column names and type generated automatically and sometimes not. First, I thinking it depends from "Model First" or "Db first" approaches.
But when I use "Model First" approach sometimes I must add all DB names manually.
Where I can find this settings? Are they Computer/User/Project depending?

when I use "Model First" approach

When creating new model, select 'Yes' on the "Model Synchronization" step of the "Create Model Wizard" (or open the Model Settings > Synchronization > Mapping and check whether the "Enable automatic synchronization of storage part and mapping of the model with its conceptual part" option is turned on).
In this case, an empty model will be created as a starting point for visually designing a conceptual model. During design of a conceptual part an automatic synchronization will be performed with a storage part.

If it is not what you mean, please describe the issues you have encountered with this in more details.

I have thinking it is something other.
