Creating Our First Link: Moving from 2D to 3D
An episode from the robotic-hand series exploring how a fully defined two-dimensional sketch becomes a parametric three-dimensional mechanical link.
This episode moves the finger-link design from a constrained two-dimensional sketch into a three-dimensional mechanical component.

Design intent
The geometry was built so that important relationships remain preserved when dimensions change.
- Pin centers remain geometrically aligned
- Hole placement follows defined constraints
- Link dimensions can change parametrically
- Design relationships survive modification
Moving into three dimensions
The sketch becomes a physical link through extrusion while retaining the relationships established in the original parametric model.
- Extrusion
- Part thickness
- Hole preservation
- Mechanical interpretation
