- Visibility control over linked models
- In-place and conceptual massing families
- Limited structural tools
- No access to the API.
In addition to allowing concurrent access, worksets are a valuable model management tool. Without them you have no method for 'demand loading' portions of your model. This may limit the scale and complexity of the projects where offices might be able to effectively and efficiently use LT on its own.
Clash detection is also eliminated from the equation
LT has all the power of the family editor required to create architectural content for most uses. Yes, adaptive components are missing but we managed quite nicely without them for a number of years and there seems to be enough content out there for the vast majority of needs.
