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.
- Upload the actual part you want quoted, not a placeholder shape.
- Keep the modeled thickness representative of reality.
- Use formed geometry when bends matter and flat geometry when the part is truly flat.
What usually goes wrong
Most upload trouble starts with a mismatch between the file and the real part.
- Uploading a conceptual solid instead of the actual part.
- Using the wrong modeled thickness.
- Sending a formed part as a flat placeholder, or a flat part as a needlessly complex model.
What a better file changes
A cleaner file makes the result easier to trust.
- Cleaner routing between laser and formed-part logic.
- Better preview quality for the customer.
- More trustworthy review decisions on complex 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 first decides whether the STEP is flat or formed.
- Flat STEP files can route to laser pricing.
- Formed STEP files trigger bend-aware checks, weight checks, and brake-fit review.
When review is normal
Review is the correct answer when the file or part is outside the safe instant-quote envelope.
- Geometry that keeps the system from finding bends or wall faces cleanly.
- Blank estimates outside the flat-part limits.
- Bend, tonnage, or thickness conditions that exceed the online rules.
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.
Should I upload a flat pattern STEP or a formed STEP?
Use the actual form you want quoted. Flat parts can stay flat, while bent parts should be represented as formed models.
What does the site do with a flat STEP file?
A flat STEP file should route to the laser pricing path instead of being treated as a failed formed-part analysis.
Can a good STEP file still go to manual review?
Yes. Review can still happen because of size, tonnage, thickness support, or commercial rule limits.
