one model, every view!
Draw one side. Get every view.
Front, plan, profile and trimetric come from the same solid, so a change in one updates the others. No redrawing the side view at midnight.

lines, kept!
Your lines stay yours.
Orthelle keeps the character of your drawing: the lean of a wall, the size of a radius. Drag across to compare the sketch with the model it became.

Same camera, same object
three steps, no plug-ins!
From paper to part list in an afternoon.
step 01
Draw or upload
Pencil, iPad, a photo of a foam study or a sentence. Write the sizes you care about on the sketch.
step 02
Shape the solid
Orthelle builds editable surfaces and parts. Anything it guessed is marked in orange for you to accept or change.
step 03
Check and send
Cut sections, explode the assembly, pick a colourway, then send STEP to engineering with the feature tree intact.

“We used to spend a week redrawing a sketch in CAD before anyone could argue about it. Now the argument starts on Monday afternoon, on a real section.”
Saga Lindqvist
Design lead, Norrow · Stockholm
“The section cut paid for the year in one tooling meeting.”
Rafael Duarte · Oddwork, Lisbon
“Our STEP files open in SolidWorks with the fillets still fillets.”

to the people who make things,
An open letter
To the people who make things,
Objects start in a pencil line. The lean of a wall, the size of a radius, the place a thumb lands. Then that line gets redrawn, again and again, by people translating it into software that asks for numbers first.
We built Orthelle so the drawing stays the source. You sketch the way you always have; the model follows, and it stays editable when you change your mind next week.
Nothing here replaces your judgement. It removes the redrawing, so you have more afternoons for the parts only you can decide.
Make more things.
