Manual review on a STEP file usually means the part is pushing a rule or the geometry is not confident enough for an instant price.
Use this page to answer the sourcing question in front of you, then carry that answer back into the quote flow with the right file and the right expectations.
These are the main ideas that usually decide whether the job goes smoothly.
Before you upload, make sure the file and part state match the manufacturing route you actually expect.
These are the practical factors that usually move cost, routing, or review outcome.
The point of the article is not just to explain the topic. It is to help you decide what to upload, what to compare, and what to expect next.
Once the topic is clear, the next move should be obvious.
The live quote flow still matters because it shows the cost impact of the decisions you are weighing.
A good article should help buyers recognize when review is the right answer instead of being surprised by it.
It matters when why step files go to manual review changes which file you should upload, how the part is priced, or whether the row stays instant-quotable.
Use the article to decide whether the part should go in as DXF, flat STEP, or formed STEP, then let the quote flow handle the next step.
Upload the cleanest file that matches the real manufacturing route and use the quote table to compare the practical options.
Use the same upload flow for DXF, STEP, and STP files. The site will guide the part into instant pricing or manual review as needed.
