2.2.7.5 Cornu Easements Modifying a Cornu
Because a Cornu is defined by its end points position, angle and radius - it can only be directly modified by dragging an end point along a track.
-
Click the Modify button (
) to activate the Modify function.
-
Click on the Cornu track. The track ends will turn into roundels
-
Left-Click the endpoint and Left-Drag it to move the endpoint along the connected track, or beyond it if you want that track extended ( but this only works in the direction of the Cornu).
-
Repeat with the other end-pint if desired
-
Once you are happy, hit the spacebar or Enter, or to cancel hit Escape.
Note: A Cornu can also be modified by moving or rotating a connected track.
