A landscape A4 sheet with four views of the model and a panel with dimensions, volume, surface area and face count.

The STEP file carries its own unit and we read it. If the model was drawn in inches, inches is what we measure. That is the difference from STL, which stores only numbers and therefore needs a guess.

Which STEP files work?

Ordinary exports in AP203, AP214 and AP242 with a .step or .stp extension — what SolidWorks, Inventor, Fusion, Creo, CATIA and NX write by default.

What does detail level do?

STEP holds mathematical surfaces, so we decide how finely a hole or a fillet is drawn. Fine gives rounder edges and a bigger file; fast is enough to check dimensions.

Is the drawing vector?

Yes. The whole sheet is vector graphics, so it stays sharp however much you zoom or print it.

No. The file is processed on servers in the Nordics and deleted automatically within 24 hours. You get a certificate of deletion.

What is the difference between STEP and STL?

STL is a shell of triangles with no unit — a hole is a polygon and the sizes have to be interpreted. STEP is the real geometry with surfaces, curves and the file's own unit. That is why STEP is what moves between designer and manufacturer, while STL is for 3D printing.

Can I open a STEP file without CAD software?

Here you can. You get dimensions and four views as a PDF without installing SolidWorks, Inventor or Fusion — enough to judge the part, quote it or pass it on internally.

Can I use the sheet as a production drawing?

It is an overview with overall dimensions and key figures, not a full production drawing with tolerances, sections and weld symbols. For documentation, quotes and talking to a customer or a supplier it is precise enough.

STEP to PDF

Turn your STEP file into a PDF sheet: isometric view, three projections, dimensions, volume and surface area. The unit is read from the file. Free and online.

Got a STEP file from a customer or a supplier and just need to see how big the part is? Upload it and get an A4 sheet with the model seen isometrically, from the top, the front and the side — plus dimensions, volume and surface area. The unit is declared inside the STEP file, so the measurements are read rather than assumed. The whole sheet is vector and prints at any size.
