What is Drive and when should I use it?
Quick answer: Drive (the Permit Drive) is your team's document library: plan sets, corrections letters, standard details, calcs, handouts. Uploading to Drive stores the file. It doesn't start a review — use New Project on Projects for that.
Steps
-
Click Drive in the top nav, or go to Drive.
-
Drag files into Drag files, folders, or ZIPs here, or click it to pick files.

-
Click Upload 1 file (or Upload {number} files) to start the selected uploads. Selecting files alone does not upload them.
-
Keep the tab open while the Keep this tab open banner shows. Each file shows Uploaded · description queued when it's done. If an upload fails, click Retry on that file.
-
Your files appear under Uploaded Files. CrossBeam adds a short description and a document type to each one.
When to use Drive vs. a project
| Use this | If you want to |
|---|---|
| Drive | Store files, keep reference material for your team, bulk-upload folders or ZIPs |
| New Project → Pre-Check Your Plans | Get an AI review of a plan set |
| New Project → Corrections Response | Get a response package for a city corrections letter |
What you can upload
- PDF, MD, JSON, DOCX, JPG, PNG, HEIC, TIFF, XLSX, or ZIP.
- Up to 1 GB per file.
- If Drive already has the exact same file, it asks you to Skip it or Upload anyway.
- If the filename already exists with different content, choose File as new version to preserve the earlier version, or Keep separate to store another document.
Who can see your Drive
Everyone on your team sees the same Drive. On an individual account, only you see it.
