To open a .cdm file, please install the Konica Minolta CDM importer from our File Import Converters webpage.
Also, please install the Minolta SCSI drivers ( ASPI ). The ASPI driver is located at http://dl.geomagic.com/binaries/support/downloads/import/Minolta_aspi.zip. If the drivers are not installed you will get an error related to missing Minolta libraries.
