There is a workaround, but the workaround may require access to AutoCAD, in addition to Microstation:1] In Microstation, save the seed file containing the CELL as an AutoCAD DWG2] In the attribute table for the point feature class to be exported, add the fields CadType, and RefName, both defined as text, with a length sufficient to accommodate the required values.CadType is calculated = "Insert"RefName is calculated to the name of the BLOCK, in this case "circle_G_2"3] run the Export to CAD tool. If run from within ArcMap, you must browse to the input data on disk. My experience is that the proces will fail if the input is displayed in ArcMap, and is selected using the dropdown arrow in the Export to CAD dialog.4] direct the output DWG file from the tool to a suitable location on the local hard drive.5] select the AutoCAD DWG file containing the BLOCK as the seed file and export.6] open the output DWG file in Microstation. The point will be symbolized with the chosen symbol. Save as a DGN, and be sure to Compress the DGN when saving to a verson 8 format. The point will be symbolized as a shared cell.
