Grading objects vs Corridors
Grading objects vs Corridors
I always find grading objects for edge grading to be, well, less than ideal and somewhat touchy to deal with. They seem ok for simple stuff, but are still quirky.
I have a site in a current project where I had reason to use 5 different grading abjects around the perimeter. All pretty simple, just grade to daylight at a specific slope. Then I paste them all with the 'main' surface into a "composite" surface... which I D-ref out.
Then, I needed one to grade to a specific target pline on the existing surface, knowing the slope would vary. Come to find out you cannot do that with a grading object, so I faked it with feature lines. Then, we decided we wanted to add a ditch along that same edge. At this point I decided to do a corridor in that section instead, and now I'm starting to wonder why use grading objects at all.
Is there a downside to using a simple corridor at the edge of a site instead of a grading object? Seems corridors have more flexibility and are easier to manipulate, plus I can now target a horizontal pline.
What am I missing?
