Hi ymg.Look If you know for example the coordinates ,the distanse and the angle you can calculate the coordinates of a new point.I have in a file the distanse and the elevetion of the new point but i dont have the angle so. I need a lisp to select the aligment of the cross section ,grab the cordinate of the midle point of the cross section ,and convert the length , elevetion txt file to (point,x,y,elev) (with point name 1,2,3 .... i don't care what).
I dont need the chainge i can do it this manualy for eatch section. For the time is very big help to convert the file
Thanks
