I am an occasional and inexperienced user of cadtools. Basically, I need it to create ditches and slopes. Of course, I also need, secondly, to create a longitudinal profile and characteristic sections from this. If I can ask for a short instruction: how to create a slope in that order: I have a bottom line (3Dpl) on level below terrein and I need to create a slope from this level up, (e.g. 1: 3 33%) until to intersect with the terrain. I have terrain triangulation * .tsd and pl3D (on set level) of the pond boundary. How to make an up cut to generate a top slope for such a slope?
If I use this tools the program hangs:
