6.1. Chapter 2¶

• Basic types of entity: point, curve, surface, solid

• Turn on control points: select shape, F10

• Turn off control points: F11

• Can move control points with shift + left click (orthogonal directions)

• Can select multiple control points to move with shift + click

• Bezier curves - ok for 2D, bad for 3D

• B-spline - better for 3D. Can import illustrator file drawn with Beziers, Rhino will convert it to b-splines

• NURBS Surface - infinitely smooth - display mesh may show straight lines - smaller number of points + curves is better

• Mesh - not smooth at all - geometry mesh is straight lines

• Use Rhino templates Help > About > New > Small objects, millimeters, 0.001mm tolerance (3 d.p.). DECIDE TOLERANCE AT THE START!

• Tolerance can’t be bigger than radii - exploded fillets.

• Draw an area that is roughly the right size - in case you are an order of magnitude out.
