Overview
Next to Commenting, the most effective way to communicate with a 3D Service is to exchange files. This is easily done by attaching one or multiple files to a 3D Project.
Drag and Drop the attachment into the 3D Project or use Click to Upload. Any file that isn't a supported 3D model will be treated as an attachment.
The uploaded files will be displayed under 3d Project Attachments. Anybody who has access to this 3D Project, including the 3D Service, will be able to download any file attachment.
