If i clip a raster in Arcmap (10.5) and the export it so as to import it into autocad 2018(vanilla using georefimg - not map3d or civil). it gives me a error message and will not attach the image. it also will not open in adobe lightroom or infraview. If I open it in QGIS and save it from there it works... Any thoughts on why? would love to skip this step and keep all of my processing in arcmap.
I determined that to export a tiff that will be compatible with Autocad you must check "Use renderer" and "Force RGB" to produce an 8bit pixel depth raster. Otherwise the the raster will be promoted to a 16bit pixel depth which autocad will not recognize. Compression, at least LZW compression cannot used either.
