i am currently working on a project where we are laying out our sanitary sewers. unfortunatly my company had paid someone else to start this project and now i am stuck fixing it. my problem is that i had to move some of the already exsiting lines do to the fact that it was plotted wrong. but i am trying to fix the stationing, invert elevations and distance. i have done the corretions needed but when i try to run the chicago tool bar that calculates all he things that need to be updated it does not allow me to do anything . does anyone have the same problem and know how to fix this problem.
