AEC-objects and MV-blocks (AutoCAD)
A CAD drawing may contain AEC-objects (Architecture, Engineering or Construction) such as doors, walls and windows. It may also include MV-blocks (multi-view blocks), which are architectural objects that can have different representations in different view directions.
AEC-doors, AEC-walls, AEC-windows and MV-blocks can be imported as constructional data via CAD Import, provided that you have placed them in a drawing layer that is mapped as constructional layer.
 | Since AEC-objects and MV-Blocks are complex, importing them as constructional data may negatively affect the performance of CAD Integrator. It is recommended to only import AEC-doors, -walls, -windows and MV-blocks that are absolutely required. |
