I am new to Civil 3D, I am working with Civil 3D 2014, I played with 2009 back in 2008 and before that it was Land desktop. I don't know if I am not following a standard workflow, or if I am missing a step.
Here is what I am doing.
I keep having the file crash after grading about 10 lots. I recover and it works find, but then the file runs very slow, and will crash. I haven't taken any classes in Civil 3d, and am looking for one in my area, but does anyone have any ideas of what I am doing wrong?
I am use to creating the vertical surface then creating points along the CL, TBC, FL, BOW then creating break lines along the points. Then create a break line for the pads, and build the FG contours from these break lines.
Thanks in advance for any help,
You might want to rough grade the pads first and target your roads based on the new grading. Might save you a little heartache. Instead of doing "Breaklines" you can use Feature Lines and set transitions and elevations.
With regard to your item #8, you will typically want to grade from the edge of the roadway or sidewalk to the pads, so the ROW usually doesn't come into play for that scenario.
As to when to tie the roads into the terrain, I like to first see how the road fits the terrain before moving on to pad grading. The visual feedback can help determine if adjustments are needed. There are likely some techniques you can use to preserve the daylighting for reference while you develop the pad grading if it helps.
" If I am grading the entire site"
If this is a typical new subdivision and the above is true, then the Corridors for the internal streets typically do not use any surface targets in the typical workflow. They are simply a part of FG.
