You can import JT files with the following conditions.

• JT files made of meshes can be imported.
• B-rep elements can be imported as SmartSolids or SmartSurfaces.
• You can import various levels of detail of geometry from a JT file. Because MicroStation does not have a concept of level of detail, only one level of detail can be imported at a time. Selecting a higher level of detail will result in a less detailed DGN model.

The JT Files Settings dialog is used to import JT files into MicroStation.
