We have a project where architectural, structural and MEP is being done in Revit, while process piping is to be done using PlantSpace XM. From Revit 2013 we used the i-model plug-in to generate i.dgn files. This was very successful! Then we tried to reference the i.dgn files into the DGN model to be used for PlantSpace. For some reason we are not seeing all the graphics, yet the elements are showing as existing in both level manager and level display. If we open the same DGN file in Microstation V8i, then we are seeing everything perfectly (but are unable to run PlantSpace as PSDS is only in XM).
Any thoughts? Is there a known issue with the i-model plugin and Microstation XM?
