STEP and STL
Download the solid as STEP and STL, together with the CAD script that builds it.
Drawing to STEP
Turn a 2D technical drawing into a 3D solid you can open in your CAD system. An AI reads the views and dimensions, builds the part and checks it against your drawing.
How it works
From drawing to 3D model in four steps
Upload the drawing
A PDF, PNG or JPG of up to 40 MB. Add notes if something is not on the drawing, such as a material thickness.
The AI builds the part
It works in the background and writes a parametric CAD script that builds the part.
It checks its own result
Rendered front, top, right and isometric views go back to the AI, which fixes what differs from the drawing, for up to four rounds.
Download
Look at the result in the 3D viewer and download STEP, STL or the script. Check it against the drawing before you use it.
What you get
A solid, checked against your drawing
Checked in rounds
Every round renders four views that the AI compares with the drawing. You can open each round's result.
PDF, PNG or JPG
Drawings up to 40 MB. From a PDF, the first four pages are used.
Nominal geometry
Tolerances, GD&T and surface finish are not carried into the STEP file, and threads are modelled as plain holes.

Your data
The drawing is stored in Imnoo's hosting in Germany and sent to an AI model to build the part. Google Analytics never receives it. Anyone you give a result link to can open that result.
Questions
Drawing to STEP FAQ
What does Drawing to STEP do?
It turns a 2D technical drawing into a 3D solid model. An AI model reads the views and dimensions, writes a CAD script and builds it, then compares rendered views of the result with your drawing and corrects it, for up to four rounds.
Which files can I upload?
A PDF, PNG or JPG drawing of up to 40 MB. From a PDF, the first four pages are used.
What do I get back?
A STEP file and an STL file for your CAD system, the CAD script that builds the part, and rendered front, top, right and isometric views.
How accurate is the model?
It is nominal geometry only: tolerances, GD&T and surface finish are not carried into the STEP file, and threads are modelled as plain holes. Check every result against the drawing before you use it for quoting or manufacturing.
Is it free?
It is free to try: 1 conversion a day without an account, 3 with a free Imnoo account and 30 with an Imnoo subscription.
