Should I use reference models or overlay models in Trimble Connect?

In the following tables, see the pros and cons of reference models and overlay models, and the operations that you can perform in these model types in the linked Trimble Connect project.

Reference models Overlay models

+ Parts of the Tekla Structures model, so more operations are available

- Increase the size of the .db1 files

+ Fast to load and display

+ Allow each user to view the model versions that they need

+ Do not affect the size of the .db1 files

- All operations are not available
