AUTOCAD CIVIL 3D - GRADING
Heads Up Grading for Parking Lots In the good ol' days, before data collectors were in wide spread use, we used to get our existing topo on paper. We'd have to throw it over a big ol' digitizing board and trace it with a puck. This was referred to as digitizing which was a very time consuming task. Later, we were able to have the paper scanned, insert the image into AutoCAD, scale it up, and trace it on screen. This was referred to as "heads up digitizing" which was a lot more efficient and faster. I've coined this term "heads up grading" for those who give up the paper, scale, and calculator way of grading to use the grading tools in Civil 3D instead. The example presented in this post will show how quickly and efficiently one can arrive at a grading solution using this method. If there are any fundamental concepts in this post that you do not understand, please refer to Mastering Civil 3D by Richard Graham & Louisa Holland . The illustration ...
