Currently if your nominated string is below a selected DTM and you want to enter a Cut slope that has a negative sign (-33.33), the Catch Point calculated will be an ascending grade (positive 33.33). The initial entered Cut Slope -33.33 will eventually intersect with the selected DTM. Therefore can negative Cut Slopes be allowed with Catch Points.
this function I’m always trying to work around - would be a great feature
Vice versa, if your nominated string is above natural surface, can we allow for a positive slope i.e. one that rises up from the string to meet natural surface when eventually the natural surface rises (a ridge line or something).
