Chapter 7: Selecting Features

Face Fillets are sometimes amazing at covering over a mess of geometry that you might think you

could never fillet. The main limitation on fillets of this type is that the fillet must be big enough to

bridge the gap. That’s right, I said big enough. Face Fillets can fail if they are either too small or too

large. Figure 7.43 shows a complex fillet situation that is completely covered by a face fillet.

Curvature continuity refers to the quality of a transition between two curves or faces, where the

curvature is the same or continuous at and around the transition. The best way to convey this con-

cept is with simple 2D sketch elements. When a line transitions to an arc, you have non-continu-

ous curvature. The line has no curvature, and there is an abrupt change because the arc has a

specific radius.

Note
Radius is the inverse of curvature, and so r = 1/c. For a straight line, r = ∞, in which case c = 0.n
