Short answer
Yes, you can send it, but your ZIP isn’t opened for an instant quote. To see each part in 3D with its price right away, unzip it and upload your files individually.

Your ZIP is saved to your quote as a reference file: you won’t see your parts in 3D, they don’t go through the DFM analysis, and your quote stays in engineering review until we finish it by hand.
You don’t have to upload them one by one. Drag all your files together into the upload box, or in “Select files” pick several: with Ctrl on Windows or Cmd on Mac. You can upload up to 10 files per batch. If you have more, upload the first 10 and add the rest to the same quote. Each part becomes a line of your quote, with its own process, material, finish and quantity, and all of them add up to one total.
Upload each part’s PDF drawing alongside it, if it has one. Leave out full assemblies, off-the-shelf hardware and native files from your CAD program: those are not quoted instantly either. More in How do I prepare my file for a quote?.
Your ZIP can be up to 50 MB; a single 3D model, up to 150 MB. Along with your 3D models, you can include your drawings and any technical files for your parts: specifications, bills of materials, quality requirements or manufacturing notes. We open it, organize your files and set up each part in your quote with its drawing. We email you as soon as your price is ready.

2 min readYou can upload a PDF, a photo or a scanned sketch straight to the quoter, just like a 3D file. Since it isn't a 3D model, that part has no instant price: you send it with Request PREMSA review, we quote it from your drawing and send you the price in the same quote.

1 min readYou can change it while your quote is a draft or already has a price. To change the 3D model, upload the new file to the same quote and remove the old part. You change the technical drawing from the part's configuration.
Upload it and we’ll make it real. One part or a thousand.
