5 - Combining 2 TIN surfaces to create new surface in Civil 3D

[@jessiemartinez7681]

is it possible to combine more than 2 surfaces, say corridors to your main grading surface?

[@johnedwards4115]

It should be if you just keep pasting surfaces to the newly created one. You just need to remember the order of pasting them. I do this when pasting a corridor on top of the existing surface topo.

Hi. Im unable to paste dem. how did you do that?

[@johnedwards4115]

Its hard to say without more information, but I guess the main thing is the DEM you are pasting needs to already be in the drawing to appear on the list. Also, I'm not sure if its required, but it would be ideal if each DEM is in the same horizontal and vertical units and coordinate system

Your instruction / guide is very helpful! Only comment I have is if you are copying and pasting from one file to another for those tin surfaces to select the base tin (your "DEM Surface" here) and copy to clipboard. In the combined drawing file, I right clicked and pasted to original coordinates. Since I geolocate everything, it aligned perfectly. @ekelwantsfood this may help you
