I created a surface in 2013 for an old project by importing a TIN from LDD, which worked fine, but the survey crew recently went back to the same site and did an update (asbuilt) with updated elevations. A good portion of the survey is still accurate and has not changed, but there was an area of new construction. My question is what is the best way to remove the old TIN lines (that are actually still connecting some old, incorrect survey points) and incorporate the new elevations that will now reflect new TIN lines in certain areas. Basically, I need to get rid of some old TIN lines and replace with new and updated survey. The surface in LDD used a point group, which was fine then, but now some of those points in that point group are incorrect.
thanks in advance for any help.

I would create a seperate surface using the asbuilt data. Then create an aditional new surface and paste the original surface first, followed by the new asbuilt surface. if you would like further instruction, let me know.
On the prospector expand your surface all the way to definition. Near the bottom of defintion there is an option for edits, right click and select the option paste surface. A list of surfaces in the drawing will pop up choose the surface you would like to paste. The order that you paste the surface matter. The second surface pasted will over ride any of the information on the first surface pasted.
