Variable slope to surface

hello,
Can someone help me on SAC, I have a road project when a portion of the embankment must be a variable slope of 1:1 to 3: 1,as input,I have PR1 and PR2 and the ditance L between the two PR, also I have the slope (PR1) and slope (PR2).

thank you for giving me your suggested for codify a SA that solve my problem.
thank you in advance.

It is really hard from my understading to transition subassemly daylight slopes. I would try a different method and use grading creation tools if possible. And use the transition command between the slopes.

If you are using grading creation tools, use the Transition Command between the 2:1 and 3:1 gradings. Refer to both links if needed.

Peter Funk created a subassembly that transitioned a daylight slope over a station range. It may suit your needs.

You could use superelevation to create a variable daylight slope.   Assign any unused superelevation parameters to the slope value of your custom daylight subassembly.

 

This is done by using API functions to access superelevation data in the slope property of the point element.  Look in the API section of the help document  for examples of using the SE API functions in SAC expressions.

 

IF((Side=Left)AND(SE.HasLeftLO),SE.LeftLO,myDefaultSlope)
