Rim & Inverts

MikeOD · 2014-03-27T18:46:00Z

Hi All, Curious to know who you all handle your Rim & Invert data once brought in by your field crews? Currently we manually type everything into CAD (Civil3D) using a calculator to subtract the invert measure downs from the rim elevations. We are looking to automate a little more to avoid any "chubby finger" mistakes, flipping a number here or there and not have to enter in numbers twice. Just trying to eliminate a step or two. What we've been brain storming with is creating a template in Excel. Here's our idea, we would export our rim elevations out of CAD (cogo points), sort them by manhole # and import them into the excel template. We would then (by theory) just need to key in the measure down and description (pipe size & type), excel does the math and then arranges into the predetermined format. We then copy the results out of excel and paste right into cad. So easy right?? Unfortunately we are at a wall with excel. Anyone have any ideas or care to share how they handle their rim & inverts?Here is an example of our rim/invert.RIM = 565.55' (STORM)48" CONCRETE STRUCTUREINV = 552.55' (18" RCP W)INV = 553.55' (12" PVC N & S)Any input is greatly appreciated. Mike

I generally don't like to shoot the invert directly, because then I have to make sure that the shot doesn't end up in the DTM. But when I do choose to do it, I just add the measure-down to the rod height.
