Fillet
The Fillet constraint can be assigned to any arc that qualifies as a fillet in the model. To qualify as a fillet, an arc must have at least one line segment or arc element at each of its ends. When an arc is constrained to be a fillet, SOLVE will ensure that it remains tangent to both the elements at its endpoints. The fillet may change radius, length or orientation as a result of the solve.
To assign Fillet constraints:
1. Select ASSIGN on MENU 2.
2. Select type Fillet.
3. Pick the arc to be constrained.
4. Pick an element at each end of the arc to complete the fillet.
5. Press END or go on to the next constraint.
Fillet-constrained arcs are represented by the fillet icon,
