C3D Files supported

The websites listed above all offer products that support C3D files. Please contact us if your product supports the C3D format to request that your website be added to this list.

The C3D-L list server

C3D-L is the e-mail discussion group for issues and information relating to the C3D file format.  Message to and from the C3D-L list are checked for and any message that contains a virus will be automatically deleted before distribution. Membership is open to anyone.  Most companies that distribute or write C3D software are members of the list, as are many C3D users.  Message volume is generally low (less than 1 message per week on average).  You can contact the list administrator via the info@c3d.org e-mail address.

How to send a message to C3D-L

Messages can be sent to the subscribers of the C3D-L list server by addressing an email to C3D-L@c3d.org - please give as much background information about your query or request as possible. Please note that in an effort to eliminate unsolicited commercial mail from the list you must be a list member to post a message.In addition, to avoid cluttering up C3D-L mail-boxes, messages with large attachments (> 500kb) may not be distributed.  These should be exchanged privately or emailed directly to info@c3d.org. Although primarily intended for C3D support and discussions, announcements of product availability, new features etc., by manufacturers or users that relate to the C3D file format are welcome.
