# Send CAD, BIM and Architecture Files to Clients and Consultants Last updated: 2026-09-23 Architecture and engineering files are big, full of references, and usually going to someone outside your company. storage.to gives you one download link for a drawing package, a Revit model or a point cloud, up to 25GB per file, with a password if you need it and no account for you or the consultant. [Upload Files Now](https://storage.to/) - Unlimited downloads - No speed throttling - No wait timers - No transfer quotas ## Why storage.to? - **Room for Real Project Files**: Central models, linked models and scan data outgrow email within a week of a project starting. storage.to takes files up to 25GB each for free. - **Any CAD or BIM Format**: DWG, RVT, RFA, IFC, NWD, SKP, 3DM, STEP, E57 and RCP files go through untouched. Nothing is converted or flattened, so references and metadata survive. - **Password-Protect Sensitive Drawings**: Add a password before a tender or planning submission goes out, and choose how long the link lasts, from 1 to 7 days. - **Nothing for Consultants to Install**: Consultants, contractors and clients open the link in a browser and download. No account, no plugin, no viewer to install. ## How It Works 1. **Package the Drawings and Models** - Package the set so nothing is missing: eTransmit in AutoCAD for DWGs with xrefs, fonts and plot styles, or eTransmit for Revit to bundle a model with its links. Zip the result. 2. **Upload the Package** - Drag the ZIP onto storage.to, or use the desktop app for large models. Add a password if the issue is confidential. 3. **Send the Link with Your Transmittal** - Paste the link into your issue sheet, transmittal email or project chat. ## Perfect For - **Models to Consultants**: Issue Revit models to structural, MEP and landscape consultants for coordination. - **Drawing Sets with Xrefs**: Send a drawing set with all its xrefs to a contractor or planner, in one ZIP. - **Point Clouds and Scans**: Hand large E57 or RCP laser-scan files from the survey team to the design team. - **Client Presentations**: Deliver renders, fly-throughs and presentation files to clients alongside the models. ## Frequently Asked Questions ### What is the best way to send CAD files to a client? Package the drawings first (eTransmit in AutoCAD bundles xrefs, fonts and plot styles), zip the folder, upload it to storage.to and send the link. Up to 25GB per file is free with no account. ### How do I send AutoCAD files with xrefs? Use AutoCAD's eTransmit, or zip the DWG together with every referenced file, keeping the folder structure. Sending the DWG on its own breaks the references on the other end. ### Can I send Revit models? Yes. RVT and RFA files, and any linked models zipped with them, upload like any other file, up to 25GB each on the free plan and 100GB each on Premium. ### How long does the link last? Links are free and last 1 to 7 days. If a model has to stay downloadable for the length of a project, Premium from $5/month keeps files permanently. ### Can we work on the model together through storage.to? No. storage.to is for sending and handing over files, not for syncing a live model. Use a common data environment for live coordination and storage.to for issues, transmittals and one-off deliveries. ## Send Your Next Issue CAD and BIM files up to 25GB, password protection, no account for anyone.
