I think something is wrong with the dates in this thread. I see 3 post from the OP that have have yesterday's date but I know were earlier posts. This includes the one about the drawing you responded to. I also got email updates about those posts. I don't know how just the dates for those posts changed. Strange!
Based on your suggestions I could create the surface. I discussed all the problems found by you in the first drawing and the topographer send me another file in the format csv. It seems ok now.
But I have another question, that I would like to have an answer, even It doesn't affect to continue me design.
When I go to drawing setting to change the units and select the units from feet to metric the elevation change.
If the units are in feet, the elevation are the same with the elevation that are in the file format csv, if I change the units in the drawing from feet to metric the elevation are not the same with the ones in the format csv.
I don't know why It happens!? It depends from the way the topographer have worked?
In attach you will found the file
I'll take a look at it when I have the opportunity.
Can you say which elevations are changing? Points? Drawing? Surface? Also. Would you please post the CSV file.
