I've had some discussions with colleagues in the office who are claiming that a tin file is more an accurate representation of a surface than a Carlson Grid.
I've always found grid files provide better profiles and sections especially when the 3D data is mainly polyline contours. In the past I have had inaccurate earthwork estimates by using tin files generated by LDD. That's why I began using Carlson Software. Now Carlson has both types of surfaces. Does anyone else have an opinion on this and had a similar experience with Tins? I am sort of old school in that I believe not every thing has to be modeled. At times grading by hand and then digitizing contours to a drawing file is the most efficient design process.
