How it works

Open and measure your STEP file in three steps

No installations, no licenses, no waiting. It works in your browser and we do not keep your files.

Step 01

Upload your file

Drag your .step file into the box to get started.

Step 02

View it in 3D

Rotate the part, zoom in, and jump to predefined views. Select points and edges to inspect the real geometry.

Step 03

Measure and weigh

Measure point-to-point dimensions and edge lengths, and get the real volume and weight based on the material you choose.

Not just a viewer

From “I can see it and measure it” to “I know what it costs to machine it”

Any viewer can show you the part. Fabriqer goes further: using the same STEP file, it helps you quote the machining by comparing your part against others you’ve previously quoted or against our database of thousands of preconfigured parts, giving you a suggested estimate of the processing time.

This is what separates a shop that quotes by eye from one that quotes with data.

Fabriqer is the quoting software for CNC machining shops

If you receive many STEP files a day and spend hours quoting, Fabriqer turns that process into minutes without losing technical rigor.

📦

Automatic CAD analysis

Upload the STEP file and we extract dimensions, volume, weight by material, and features (holes, threads, flats).

Comparison with parts already quoted

Compare your part with similar parts you have quoted before or with our database of thousands of preconfigured parts to get a suggested estimate of the process time.
