Reflection
The Reflect command calculates the reflected rays from selected incident
rays at the intersection point with a reflection boundary curve. The reflected
rays remain selected. Pre-selection of incident rays is possible.
Options:
Trim Rays at boundary: Yes / No
Extend Rays to boundary: Yes / No
If a single ray is reflected the reflected ray angle to vertical is printed
to the command history.
MeasureAngle
The MeasureAngle command measures the angle to the vertical.
