Michael Nabatieh Posted October 28 Posted October 28 Hi everyone, I don't know if it's even achievable or not, but I thought I'd post it anyway. What I need is this : user inputs: Elevation difference Offset slope maximum elevation Offset a 3D polyline using the given elevation difference and slope (%) check if one of the vertices is above the maximum allowed elevation, then change the slope (decrease the slope) so all the vertices are bellow the maximum allowed elevation. Anything that can help is really appreciated ! Thanks in advance Quote
CyberAngel Posted October 28 Posted October 28 There are several AutoLISP routines out there, some of them free, that will draw contours for you. It shouldn't be hard to modify one of them to do what you want. You'll have to identify the highest point on your polyline and use that to calculate the parameters of your drawing function. Quote
BIGAL Posted October 28 Posted October 28 As your playing with 3D elevation & slope parameter in simple terms would be a distance, but a 3dploy can have twists and turns so which direction is the new point implied? Need a dwg to look at. Quote
SLW210 Posted October 29 Posted October 29 Give CadTools a try, it has a lot of tools for contours and similar. Quote
