I am not sure it was clear what I was trying to say, and what Matt commented on. The command in picture below does not need to be there. It gets hit accidently when trying to select the command below it. Agree you need to re-interpolate, when you add hyd item or pipe, and when Irricad doe this, it is reasonably quick. Its when it does the whole lot again that is annoying, when you hit this button by accident.
What the "would you like to re-interpolate" should be on this command only, if your not getting rid of it, not when its an auto command, like when you change a valve location or submain pipe and you hit zone design anaylsis (auto interpolate), you don't want this pop up coming up, for a quick re-interpolate that has to be done, this would be even more annoying.
What Matt was trying to say, Irricad auto interpolates anyway, if you don't hit this command and try to do zone design, mainline design or DEM view, so why have it there. (or pherhaps its to prompt your to have a break

)
