01 / Sketch
Every dimension
has a purpose.
Start with a line. Add a dimension, a constraint. Your sketch becomes the foundation of a part you can keep refining.
Set the rules
Keep two lines parallel, center a hole, lock a distance. Constraints preserve your design choices.
Change one dimension
The profile updates while its constraints hold. Explore variations without starting over.
02 / Model
From a profile
to a complete
assembly.
Extrude, cut, round and assemble. Go back to a dimension and let the rest of your model follow.
