I am receiving my EG surfaces from the surveyor in LandXML format. He is creating them in Land Desktop and exporting them to the XML. I am opening them in Civil 3d. On a couple of projects he has had to make updates to the surface and send me a new one, when he does this I notice "holes" in the surface. Usually I notice them when I create profiles. The drawings he sends to accompany the XML file contain contours (even in the area of the "holes"). He does not see holes on his end.
Has anyone experenced this. I believe it is related to him merging multiple surfaces on his end and it leaving some holes, but clearly he is able to produce contours with no blank spots, so I don't know for sure. I am gonig to discuss his method in more detail with him, but was hoping to get some ideas of the issue first.
Once before this happened and since I had information for the one point that existed in the "hole" area I was able to add that point to my surface and edit my tin to match his to fixt it. Now I am working with a much larger surface and this is not a reasonable fix.
Thank you in advance!
