Protected handoffEncrypted transfer
Files are encrypted while they travel between the user's browser and SendThisFile.
Engineering file transfer
Send large engineering files without forcing them through email.
Share CAD files, 3D models, drawings, simulation output, and project packages with clients and partners through a controlled download workflow.
SendThisFile protects files during transfer and temporary storage, lets you apply the recipient protections available with your plan, and shows the delivery outcome in Activity.
The real job
Move finished engineering work across company lines.
Engineering deliverables often need to leave the systems where they were created.
- ClientDrawing set
- SupplierManufacturing package
- ContractorCurrent model or specifications
SendThisFile gives that external handoff a clear path: upload the files, address the transfer to the recipient, apply the protections available with your plan, and check what happened afterward.
A controlled download workflow
From project package to recipient in three steps.
- 01
Add the recipient and files
Address the transfer, then add the CAD files, models, drawings, simulation output, or project package you need to deliver.
- 02
Protect and send
Apply the recipient protections available with your plan, review the handoff, and send the download link.
- 03
Check Activity and end access
Confirm the delivery outcome in Activity, see when access is scheduled to end, and end access sooner when needed.
Verified controls
Protect the handoff without adding a collaboration system.
SendThisFile focuses on the transfer and temporary access window around the files you deliver.
Temporary storage
Files remain encrypted while temporarily stored awaiting the recipient's download.
Recipient protection
Apply the recipient protections available with your plan before you send.
Visible outcome
Activity shows the transfer and delivery outcome, while availability controls let you end access sooner.
Engineering handoffs
Useful when the deliverable has to leave your organization.
CAD files and 3D models
Hand off design packages to clients, reviewers, fabricators, or outside engineering partners.
Drawings and specifications
Deliver drawing sets, specifications, and supporting project documents together.
Simulation output
Send analysis results and output files that do not fit comfortably in an email attachment.
Bids and submittals
Move bid packages, submittals, and review materials across organizational boundaries.
Manufacturing and vendor packages
Share the files a supplier or manufacturing partner needs for the next step.
A clear capability boundary
Secure file handoff—not an engineering workspace.
Use SendThisFile when you need to deliver project files to a client, supplier, contractor, or partner through a controlled download workflow.
It is not CAD co-authoring, version control, real-time sync, project management, or a native ANSYS, MATLAB, or SolidWorks integration.
Common questions
Practical answers before you send.
What is engineering file transfer?
Engineering file transfer is the handoff of project files—such as CAD files, drawings, models, simulation output, or specifications—from one organization or person to another. SendThisFile provides a controlled download workflow for that handoff.
How can I send large engineering files without email attachments?
Add the recipient and files in SendThisFile, apply the protections available with your plan, and send the transfer. The recipient uses the transfer link to download the files while they are available.
Can I send CAD files, 3D models, and simulation output?
Yes. You can use SendThisFile to hand off these files as files. SendThisFile does not open, edit, co-author, or provide a native integration with engineering applications.
How does SendThisFile protect engineering files?
Files are encrypted while they travel between the user's browser and SendThisFile and while they are temporarily stored awaiting download. Recipient protections vary by plan.
Can I check whether the recipient downloaded the transfer?
Activity shows the transfer and delivery outcome. It also shows when access is scheduled to end, and you can end access sooner when needed.
Is SendThisFile a CAD collaboration or version-control system?
No. SendThisFile is for secure file handoff. It is not CAD co-authoring, version control, real-time sync, project management, or a native ANSYS, MATLAB, or SolidWorks integration.
