I created a new User-Defined Property called As-built elevation. Then created an input fromat called As-Builts, where the elevation gets read into this user defined property instead of the point elevations.
Them I elevate all points to the design surface. This fills in the point elevation column, and I can using another defined format export both elevations to a csv and into a spreadsheet, converting that to any report I want.
I've also created an expression which is the As-built elevation minus Point elevation. Then used that expression in a label, this labels up all my points with the elevation difference and I get a nice conformance check plot.
Pity one can't created "calculated" User Defined properties, i.e. one whose value is calulated from one or more point properties.
Thanks for the tip!!!
If terramodel has it... why doesn't civil 3D? Is somebody slacking off, throwing rubber bands at the wall at autodesk???
I'd like to see a POINTS to SURFACE elevation deviation report choice. Surveying has been in need of this since the beginning of days. Need to hand a CUT/FILL report to contractors for road construction, parking lot paving, etc... Need this feature.
One of the beauties of Civil 3D is that it includes a programmer interface, making it easy to solve small issues like the one presented in this thread. The following code is an example. If it works for you, you are welcome to use it as-is or change it so it does work for you.
