If you haven't noticed already, you can share your CAD files privately in GrabCAD library with other users. You only need to know their name. For each file you upload there are 3 options: Public, Private, Shared. You can set the sharing in the upload form or in the file view under the name of the file. Here's how it works.
Public files
1. The uploaded file is public and everybody can download it.
Option one in the sharing window.
The file will be shown under your models like every other file.
Private files
2. The uploaded file is private. Nobody besides you has the access to this file.
Option two in the sharing window.
The file will have a tinted screenshot with a lock icon under your files.
Shared with someone
3. The uploaded file is shared with another user or e-mail. Only you and the other person has access to this file.
Option three in the sharing window.
The file will have a small sharing icon on top of the screenshot under your files.
Files that somebody else has shared with me
Files that are shared with you can be found again under my files in the "Shared with me" tab.
Don't forget to back up your files!. Unfortunately we've heard from many of you guys, that you have blown your hard drive or damaged your external flash drive. Upload your important files to GrabCAD so you don't have to re-model something that took 50h to make.
If you have any suggestions or ideas how to improve the sharing functionality let us know @ indrek@grabcad.com
Happy sharing!
