Before Upload
What to get right before the file goes in.
These are the prep decisions that usually make the difference between a clean quote and a frustrating one.
What to check first
Run through these basics before upload.
- Model the real thickness you expect to buy.
- Upload the final formed geometry instead of a placeholder concept.
- Expect review when bend length, tonnage, or geometry confidence pushes the part outside online rules.
What usually goes wrong
Most upload trouble starts with a mismatch between the file and the real part.
- Uploading a placeholder block model instead of the real formed part.
- Modeling the wrong thickness.
- Expecting a very long or heavy bend to stay in the instant-quote path.
What a better file changes
A cleaner file makes the result easier to trust.
- Better models reduce false review triggers.
- Cleaner geometry improves 3D preview quality.
- Customers understand why review is normal on some formed parts.
How The Tool Responds
What the quote system will do with the file.
The site is not just storing the file. It is classifying the part, building preview logic, and deciding whether the row deserves an instant number.
What the system is looking for
The quote tool is trying to route the part into the right manufacturing path.
- The site tries to find the bends, the likely flat blank, and the brake fit.
- Formed STEP models can stay instant-quotable when the geometry is simple and the limits are met.
- The system uses review when the bend logic is unclear or the brake requirements get too aggressive.
When review is normal
Review is the correct answer when the file or part is outside the safe instant-quote envelope.
- Bends longer than the online brake limit.
- Estimated tonnage above the supported online limit.
- Complex or unclear geometry that needs manual estimating judgment.
How to keep the next step obvious
The easiest way to avoid friction is to upload a file that matches the real part state.
- Use a flat file for flat parts.
- Use formed STEP for bent parts.
- Let quantity, material, and thickness changes happen in the quote table instead of in the CAD file.
FAQ
Questions buyers ask before they upload.
Why is STEP preferred for bent sheet-metal parts?
STEP preserves 3D formed geometry and is better suited for bend-aware review than a flat DXF alone.
Will the site quote every formed part instantly?
No. Parts that exceed bend length, tonnage, thickness, or confidence limits are routed to review.
What if my formed part is actually flat?
Flat STEP parts should be treated as laser-cut parts rather than being misclassified as failed formed parts.
