01 / Sketch
Start with a line. Add a dimension, a constraint. Your sketch becomes the foundation of a part you can keep refining.
Lines, arcs, circles and profiles. The tools you need to turn an idea into precise geometry.
Keep two lines parallel, center a hole, lock a distance. Constraints preserve your design choices.
The profile updates while its constraints hold. Explore variations without starting over.
02 / Model
Extrude, cut, round and assemble. Go back to a dimension and let the rest of your model follow.
