Civil 3D 2007 Grading Features

Civil 3D 2007 Grading Features

Here are some of my favorite NEW grading features in Civil 3D 2007

Elevation Editor
We had the elevation editor in the 2006 version but it has been improved. When you click on a specific elevation in the elevation editor, there is now a visual marker in the drawing indicating which PI you are editing. Now we can intuitively use the elevation editor to adjust feature line elevations efficiently.

Quick Elevation Edit
This one is very cool, similar to the elevation editor above except there is no dialog interface. It allows you to scroll through the PI's of a feature line and change the elevations quickly by typing in a value at the command line or through dynamic input; it also shows a visual marker so you know where you are. Additionally, it allows you to jump between PI's in order to change the grade or slope between two elevations. Very useful command and very efficient.

Insert Elevation Point
If you need to add an additional PI along your feature line path, you can freely pick anywhere along the feature line to add an additional point and then you are prompted for the appropriate elevation

Elevations from Surface
This existed in the 2006 version, but it is worth noting. Don't underestimate this command; it is useful for many different design scenarios. If you are not familiar with it, it will drape any feature line (polyline) onto a surface, essentially creating a daylight line (in a sense) that you can grade from...

Insert PI
Similar to the Insert Elevation Point except this option allows you to pick a new point anywhere and then add the elevation whereas the "Insert Elevation Point" has to be along the current path of the feature line

Join Feature Lines
Pick any two feature lines, even if where they connect they don't share the same elevation. Just pay attention to which object was created lasts. If you have two endpoints you want to join but they are at different elevations it will always assign the elevation of the point that was added last

Fillet
You an now fillet feature lines even if they originated from two 3D polylines
