When working in a model that was created using 
  Revit, the 
  Revit LT user can add and modify some types of elements, but not others. 
The 
  Revit LT user 
  can do the following: 
- Add elements that are supported by 
	 Revit LT. 
  
 
- Add instances of families that were loaded into the 
	 Revit model, even if the family categories are not generally supported by 
	 Revit LT. 
  
 
- Move elements that were created using 
	 Revit but that are not supported by 
	 Revit LT, such as (not a complete list): 
	 
- Adaptive components 
		
 
- Assemblies and parts 
		
 
- Panel-based curtain elements 
		
 
- In-place elements 
		
 
 
   
- Move and modify the following elements created using 
	 Revit: 
	 
- Masses 
		
 
- Sketched stairs
		
 
- Slanted columns 
		
 
 
   
The 
  Revit LT user 
  cannot do the following: 
- Load additional families for unsupported categories into the model. 
  
 
- Copy and paste elements from a linked model into the current model.
