Creating 3D files for grading

[Matthew Timion]

Hello all,

We recently purchased SurvCADD XML for it's ability to produce 3d files for
automated grading (that was the selling point, at least). I am still very
unsure as to the process for creating these files. My general assumption is
that after assigning elevations to a DWG file, something must be done. Do I
need to convert this file to points before I can go on? Can someone help
me? Can anyone give me a very basic instruction guide from start to finish?

Thanks a million,

What type of 3D file do you want to end up with? SurvCADD has the ability to generate a 3D grid file or a triagulation file. Either of these will work in products such as Carlson SurvCE or Tsunami. What is your automated grading software? What sort of input file does it require?

===========Basic instructions=============To create a 3D Grid file:
In the DTM module, choose Make 3D Grid File from the DTM menu.

To create a triangulation file:
In the DTM module, choose Triangulate and Contour from the contour menu. Check on "Write Triangulation File".

If you have any more questions, let us know
