Send CAD drawings and 3D renderings

You are handing over a project stage, not a simple attachment. The same package holds PDF drawings, .dwg files, .rvt models, references, textures and 3D renderings. The client wants the images, the structural engineer wants the right model, and the services consultant has to get the same revision. Once the package is bigger than an email will take, splitting it across several messages turns the handover into a manual check: who got part three, which version was opened, and which file is missing?

Transferify fits the clearly bounded moment of a handover. You put the documentation in one transfer, choose between a hosted delivery and peer-to-peer, and send one link. The recipient downloads in the browser, with no account. A transfer of drawings stays tied to one revision and one message, not to a series of attachments with no context.

The project handover, step by step

A well-prepared package cuts the questions after sending and helps you show what you handed over, even though Transferify does not replace your internal project register.

1. Separate work in progress from the files released to the client or to consultants.
2. Name the archive after the project, the stage, the revision and the date, not "final-final".
3. Add an index PDF listing the files, units, coordinates and the software and version each one needs.
4. Choose the hosted mode for a later download, or peer-to-peer when the package is very large and both sides can stay online.
5. Send the link with the handover note, and keep the record of revision and responsibility per file separately.

You can add the whole project folder with Add a folder or by dropping it on the page, and the recipient gets the same subfolders back, as the guide on how to send a whole folder explains. An archive brings order, but it does not make a BIM model or a set of renderings small enough for email. If size is your problem, start with how to send large files, not with one more attempt at compression.

Hosted link or peer-to-peer for a large model

The hosted mode works when the recipient downloads later. You upload once, send the link and can close the laptop. It is the practical choice for a planning set, a batch of renderings or a model that several people collect at different times.

Instant peer-to-peer is the choice for a model or archive above your plan's hosted limit. Instant is free up to 5 GB on the free plan, and any paid plan unlocks any size. It delivers live, though: your browser and the recipient's must stay open and connected until the end. For an arranged handover to an engineer that can be simpler than cutting the model into pieces; for a client who opens the link tomorrow, hosted fits better.

The limits that belong in your calendar

On the free plan the number of transfers is not capped, but live transfers share one storage allowance. You have 50 downloads in a calendar month, and links close after 1–3 days. That covers the running handovers of one project, not keeping several live revisions for a site at once.

Password protection and download alerts start on Basic. Zero-Knowledge encryption is available on the Premium plan. An alert tells you whether and when a download started, never who started it. Extending the expiry of a sent transfer starts on Plus. Premium adds download statistics, your logo and colours on every delivery and a branded link address. Check the current plans and limits before a handover to many recipients.

Confidentiality for drawings that are not public yet

The documentation of a project out to tender, a private house or a piece of infrastructure should not travel as an open link down a long email chain. From Basic you can set a password and share it on a different channel. For projects where the transfer service itself must not be able to read the contents, turn on Zero-Knowledge encryption, on the Premium plan.

That option also moves responsibility to you: if you lose the link needed to decrypt the files, Transferify cannot open them for you. Record the recipients, the revision and the channel you used for the access details in the project register. The transfer protects the delivery; the office procedure protects the whole document cycle.

When a CDE or a shared drive is the better choice

When architecture, structure and services work on the same models every day, you need versioning, comments, folder-level permissions and history. A common data environment or a managed drive wins in that workflow. Transferify does not try to be the project library; it is better at the bounded handover of one revision to someone who simply has to download it.

In the same way, email may be enough for a PDF of a few pages. The guide to email attachment size limits helps you decide before you start an upload. When the job is on site rather than in the studio, the page for construction and trades covers drawings, quotes and site photos.
