How to share an Altium project

An Altium Designer project opens in Altium Designer. For anyone without a licence, that means a PDF, a screenshot, or a link that does the rendering for them. Here is what each one gives the person you send it to.

Option 1: export a PDF

Smart PDF produces a document of the schematic sheets and, if you add them, the PCB layers. It works everywhere and needs nothing installed. It is also frozen: no BOM to sort, no layer to toggle, no 3D, and a reviewer cannot tell which revision they are holding once two PDFs are in the same thread. Every change means another export and another attachment.

Option 2: the Altium 365 Viewer

Altium's free viewer at altium.com/viewer opens a project you drag in, with no account on either side, and shows the schematic, the PCB in 2D and 3D, and a BOM. The upload lives for your browser session; a share link lasts 48 hours, and Altium notes that such links can be indexed by search engines. With a free Altium account the design can be saved to a personal space permanently, with comments and downloads. If your team's project lives in an Altium 365 workspace, the workspace shares it the same way, with project history and comparisons behind it.

That is the quick answer for a one-off look at one Altium design, and the native answer inside a team that already lives on 365. It is not a home for the project next to your KiCad boards, your public work, or a collaborator's design from another tool, and a personal-space snapshot carries no version history.

Option 3: upload the project to BoardRepo

Zip the project folder, including the .PrjPcb, the .SchDoc sheets, the .PcbDoc, and any libraries and outputs alongside them, and upload it. BoardRepo converts the design for viewing and gives the project a page: the schematic sheets and the PCB drawn in the browser, an extracted BOM, the file tree, and every original file downloadable exactly as you zipped it. The reader needs no account and no Altium.

Two things to know about the conversion. It is for viewing, so keep working from your original project and verify anything that matters in Altium Designer; BoardRepo keeps the original beside the converted copy for exactly that reason. And fabrication outputs are not generated from a converted board: BoardRepo does not produce Gerbers from a lossy import. If you include your own Gerbers or position files in the zip, they are listed and downloadable like every other file.

Everything else works the way it does for any board. Upload a new revision and it becomes the next numbered version; the link keeps pointing at the latest, older versions stay downloadable, and a signed-in reader can compare two versions visually. The board can be public, an unlisted link, password protected, or kept inside an organization.

Choosing between them

A PDF is fine for a one-off glance, and so is a 48-hour viewer link. Altium 365 is the right home inside an Altium team that already lives there. BoardRepo is for the case where the reader is outside that circle, or the link has to outlast the week: a client, a contract manufacturer, a firmware engineer, a reviewer who uses KiCad, or the public. The link is the same kind of link for every one of them, and it stays current as the design moves.
