I've just had the same problem.
There four methods within AIS_InteractiveContext to do that:
- SetDeviationAngle
- SetDeviationCoefficient
- SetHLRDeviationCoefficient
- SetHLRAngle
One peculiar thing is that SetDeviationAngle calls SetDeviationCoefficient instead of SetDeviationAngle (from the Prs3d_Drawer). But it works anyway.
