Here is the problem:
We have original surface x,y,z, point data for a large surface (call it Surf1).
We built Surf1 and created a TIN consisting of 3D lines.
We then added as-built data by building the as-built surfaces (call them Surf2, 3, and 4) and creating TINs consisting of 3D lines and adding them to Surf1 by removing the 3D lines from the as-built areas on Surf1, adding the 3D lines for those areas from Surf2, 3,and 4, and rebuilding the surface (call it Surf5).
We now have data (x,y,z point data and 3D breaklines) for an additional area (call it Surf6) adjacent to one side of Surf5.
Using Autocad LDD 2005, I am looking for the most efficient way to add Surf6 to Surf5.
To put it simply:
Using Autocad LDD 2005, I am looking for the most efficient way to add additional surface data consisting of 3D points and breaklines (or 3D TIN lines) to a surface consisting of 3D TIN lines?
We have Civil 3D 2009 if there is a better way in C3D 2009 to build this surface and export it back to LDD 2005.
