Should I send native CAD files or an exported format?
Use the format required for the recipient’s task and software. Include an exchange-format export when appropriate, but confirm what information the recipient needs.

How it works
Send CAD Files Online — step by step
01
Agree on the format
Ask which CAD formats and versions the recipient accepts. Do not assume that a native file opens in another application.
02
Collect related files
Gather referenced parts, drawings, and other required resources. Preserve the folder structure where paths matter.
03
Check an independent copy
Open the delivery from a separate location and verify the assembly and drawings. Confirm revision labels and units.
04
Upload and explain the status
Send the FileFlap link with the part or project number. State the requested action and keep formal approval in your established process.
Before you start
What to know before you transfer
A CAD file can depend on parts or drawings that are not stored inside the main document. Before sharing, find out whether the recipient needs an editable native project or an exchange-format export. Label the package as a review, quotation, or approved production delivery so its intended use is clear.
Checklist
Prepare your files
| Item | What to send | What to check |
|---|---|---|
| Model files | The native or exchange format requested | Check receiving-software compatibility. |
| Referenced parts | Files required by the assembly | Confirm the delivery opens without missing references. |
| Drawings | Applicable drawings in the agreed format | Match their revisions to the models. |
| Revision note | Units, version, and delivery purpose | Identify the required review or approval step. |
Common mistake
Mixing current and superseded revisions
Give the delivery one clear revision and explain what it replaces. Downloading a file does not constitute engineering approval or permission to manufacture it.
