Hi,
I'm doing a track off/on and to draw the alignment onto open rail using a single element regression, it appears that I need to use trial and error.
The following is my current method:
After creating a regression line using the survey, I select "single horizontal regression" and using the "horizontal curvature diagram" I create an alignment. I open up the horizontal regression report and look through it to see if the line meets my requirements (I require the slew of the line to be less than +/- 15mm), I then edit the length and location of the alignment (via the toggle points on the curvature diagram) until the report states that it fits my requirements.
There must be a more efficient way of doing this? What is it?
Is there a method to set the maximum slew of an alignment and then draw it?
Many thanks.
You can have a try with the quick regression
