Know who's opened your shared CAD files
Sending CAD drawings, technical models, or engineering packages to clients and collaborators is only productive when you can see who's engaged with them. WeTransfer lets you track when recipients preview or download your files, so you know exactly where a project stands before your next check-in.
Keep count of who views your transfer
When CAD files move between design teams, contractors, and approvers, a sent confirmation is rarely enough to know whether the right people have actually looked at the work. WeTransfer's Transfers panel records preview activity and download events for every transfer you send, giving you a clear, named picture of recipient engagement. Enable download tracking before you send, and each access event is tied to a verified email address and a precise timestamp, so your project lead or account manager has real evidence to work from, not a hunch. For sensitive technical files like unreleased product geometries, proprietary assemblies, or client-specific schematics, you can restrict access to a defined list of email addresses so only the contacts you intend can open the transfer. Your CAD files arrive exactly as exported, with no compression, re-encoding, or quality loss.

FAQs
All your questions answered.
Yes. WeTransfer's Transfers panel distinguishes between in-browser preview activity and a completed file download, so you can see whether a contact has browsed the transfer or saved the files to their device. Enable download tracking before sending and each event is tied to a verified email address with an exact timestamp, giving you a named record for every interaction with your CAD transfer.
Before you click Transfer, open the transfer settings panel and enable download tracking. From that point, every preview and download event on your CAD files is recorded in the transfer's activity log inside your Transfers panel. The setting must be enabled by you as the sender before the transfer goes out, so it's worth making it part of your standard workflow when sharing technical deliverables.
Yes, using the restricted access option you can specify a list of email addresses that are permitted to open the transfer. Anyone who visits the link but isn't on your list will be blocked from accessing the files. You can update the access list after sending from the transfer details page, and changes take effect immediately, so you stay in control even after the files are out.
Yes. When download tracking is enabled, each access event is tied to the specific verified email address of the person who previewed or downloaded the transfer. If you send to multiple engineers, contractors, or client contacts, the activity log in your Transfers panel shows a separate named record for each person, so you can tell exactly who has engaged and who hasn't.
No, recipients don't need a WeTransfer account to access a transfer. They can open the download link and preview or download your CAD files directly in the browser without signing up. If you've enabled restricted access, they'll need to verify their email address to confirm they're on your approved list, but that doesn't require creating an account.
