Hi Juan, First could you tell me what version of Bentley Descartes and IrasB you are using? Second as far as I know Bentley Descartes has never had the capability of attaching images, when loaded Bentley Descartes just adds extra functionalities to manipulate raster, amongst other things. This is the task of Raster Manager to add new raster to a DGN. I try the following workflow on my side : - Attach a .CIT raster file to a DGN file with Raster Manager V8i. - Close the .DNG file and reopen in with IrasB XM. Note that the .CIT attached previously was visible in the Bentley I/RAS B - Layer Info dialog. - Draw a circle on the .CIT raster file. - Close the .DGN file in IrasB XM and reopen it Descartes V8i. The circle was still in present in the .CIT file. Note that IrasB might not support all the file format supported by Raster Manager. Also IrasB doesn`t handle by default binary image whose pixels are not rectangular. Did you check if any error messages appears in the message center of IrasB? Thanks, Mathieu
