In TopSolid, when we perform a continuous 4/5-axis operation, an unroll occurs in the retraction of this operation to return all axes to their initial values.

In our example, the A axis of the divisor returns to 0° at the end of the operation:

To avoid this unrolling, we can insert a " Numerical reset of axis " in the operation retraction, which will set this axis to 0° without unrolling the axis (at the shortest point):
