The AutoCAD LT behavior is the same as it was in previous releases. In AutoCAD LT, you can use only one UCS in each drawing file. Work with Multiple User Coordinate Systems: In AutoCAD, you can choose to use a different user coordinate system (UCS) in each viewport in a single drawing file.However, the drawings created in AutoCAD that contain LispVariables can be opened without errors in AutoCAD LT, and the cached value is displayed. Work with Fields: In AutoCAD, you can insert LispVariables fields, which are not available in AutoCAD LT.However, you should understand how AutoCAD LT handles AutoCAD-only features.
AutoCAD LT offers full compatibility when working with AutoCAD drawings.
