Share the drawing,not the right to keep it.
DekkoCORE lets engineering and design teams share drawings, models and specifications with clients, contractors and fabricators at exactly the access each one needs. Files of any size go up through the Upload Accelerator, and every view and download is recorded.

Layer · Questions
Asked by engineering and design teams.
Can recipients view CAD files without downloading them?
The secure viewer opens PDF, Word, Excel, PowerPoint, text, image (including SVG), MP4 and MP3 files. Native CAD formats such as DWG or STEP aren't viewable in the browser, so share PDF exports View only and give Download access to native files only to the people who need them.
Is there a file size limit?
No. DekkoCORE has no file type or size limits, though your tenancy can set one. Very large uploads take time on a slow connection, which is what the Upload Accelerator for Windows is for. For more than 200 files, zip them first.
What's the difference between Listing only and View only?
Listing only shows that files exist, with their names, sizes and dates, and nothing more. View only lets the person open supported files in the secure viewer, but not download them.
Can a contractor reshare our drawings?
Only people with Manager or Full permissions can reshare. A Hub can also restrict external uploads and sharing altogether, and every share is recorded in the audit log.
What happens when a share expires?
Everyone it was shared with loses access automatically. The file isn't deleted, and your own access doesn't change.
Can we sync design folders to our file server?
Yes. DekkoDrive for Windows keeps a Hub's folders in step with local or network storage, encrypting and decrypting as it goes, and files placed in a shared folder are shared automatically.
