Collaborate on CAD files without the back-and-forth
WeTransfer lets architects, engineers, and designers share CAD files and gather feedback directly on each file, inside the browser. Reviewers can open, comment, and mark favorites without installing anything or creating an account, while you stay in control of the transfer and its settings from your own account.
Collaborate on every transfer
Getting useful feedback on CAD work usually means chasing replies across emails and trying to match comments to the right layer or view. WeTransfer keeps reviewer responses tied to the actual file, so when a structural engineer or client opens your transfer in the browser preview, they can comment on each file without needing to download or sign up first. You get an email notification each time a new comment lands, so input from multiple reviewers stays visible and easy to track across a project. From the transfer detail page, you can rename the transfer, revise its description, and toggle commenting settings at any point after sending, which matters when design iterations move fast or a revision supersedes the version already in someone's hands. For confidential drawings or proprietary designs, password protection and access restriction to specific email addresses are available on every plan.

Yes. Recipients can open supported file types in the browser preview and comment on individual files without downloading anything or creating a WeTransfer account. They just need the transfer link. Comments are tied to the specific file they were left on, so feedback from a structural engineer or project manager stays anchored to the right asset.
WeTransfer supports in-browser preview for a wide range of file types including images, PDFs, video, audio, and common office formats. For CAD workflows, you can send any file type, including DWG, DXF, and 3D model formats, and your files arrive in their original quality with no compression or re-encoding. If a specific CAD format is not previewable in the browser, recipients can still download the original file and comment via your transfer detail page.
WeTransfer sends you an email notification each time a reviewer adds a comment to a file in your transfer. You can also open the transfer detail page from your account at any time to see all comments and check which files have received feedback, so nothing slips through during a busy review cycle.
Yes. From the transfer detail page in your account, you can rename the transfer, edit its description, and change comment settings at any point after sending. This is useful when a revised drawing supersedes the version you already shared, or when you want to close commenting once a review round is complete.
Every plan includes password protection and restricted access options. You can lock a transfer behind a password that only your intended reviewers know, or restrict access to a specific list of email addresses so that only named recipients can open the files. Both options are available on free and paid accounts, and you can apply or update them from the transfer detail page after sending.
