Drop a STEP file.Read the part.Nothing is uploaded.
Outer dimensions, volume, weight, surface area, the projected area along each axis and an indicative locking force, read by OpenCascade from the geometry itself, with the part in 3D. It all runs in this browser tab: the file isn't sent anywhere.
No STEP file to hand? Open one of ours, from the quote assistant's examples:
01Boundaries
What it reads,and what stays with you.
It reads
- Outer dimensions, overall and per axis
- Volume, and weight for the material you choose
- Surface area
- The part's shadow along X, Y and Z, at 0.25 mm per pixel
- An indicative locking force from that area and your pressure
Your team decides
- The opening direction and parting line
- Cavities, runners, gates and overflows
- Undercuts, slides and lifters
- The press, the steel and the price

Ask Carlos directly. He answers every email himself, within one working day.
01Is my file uploaded?
No. The page loads OpenCascade into this browser tab and reads the file there. Nothing about the part is sent to us or anyone else; the only figures we ever see are the ones you choose to send with the button.
02How accurate are the figures?
Dimensions and volume come from the geometry, meshed to within 0.2 mm: a flat-faced part reads exactly, a round one up to about 0.3 % small. The projected area is the part's shadow drawn at 0.25 mm per pixel, within about 1 %. The locking force is only as good as the pressure you assume.
03Why does it suggest that opening direction?
A STEP file doesn't say how the part sits in the mould, so it suggests the axis with the largest projected area, which is usually the one the force acts along. If your parting line is elsewhere, pick another axis and the force follows.
04Does it work on assemblies?
It reads every solid in the file and measures them together, so the force for an assembly is for all of it at once. For a quote, export the single part.
05Is this the quote request assistant?
It's one step of it. The assistant measures every STEP file attached to an incoming RFQ, puts the figures on a summary sheet in your team's language, lists what's missing to quote and drafts the reply. This page lets you try the measuring on your own files.
03Next step
Measure every RFQbefore anyoneopens it.
The quote request assistant reads the STEP files on every incoming request, puts these figures on a summary sheet and lists what's missing to quote. Twenty minutes to see whether it fits your shop.
