Depth Profiles from EG

  

Lets talk about 3 options to get create a Depth Profile in Civil 3D: 

First Option:

Creating a copy of the EG surface profile it will be and exact match. We will then drop the copy the needed amount. However if the Alignment path were to change or Surface was to be edited the copy would NOT be up-to-date

     1. Use the AutoCAD command to copy the EG Profile. 

     2. Go into Profile Properties dialog box: Rename it, set a different Style and change the Update Mode to “Static”.

     3. Lower it using the Edit Geometry tools > Raise/Lower PVI Elevations command.

Second Option:

Creating a Feature Line from the Alignment and EG Profile that can be Projected and Lowered.

     1. From the Ribbons Home Tab > Feature Line > Create from Alignment.

     2. Choose of what profile to follow, Uncheck the Dynamic Link box and option set options to weed out vertices.

     3. Next add Feature Line to grid, Select the Profile View > from Ribbon > Project Objects to Profile View button.

     4. Make sure the “Use Object” is set for elevations in the Dialog Box Options.

     5. Lower the Feature Line the Ribbon or Right Click command to Raise/Lower.

Third Option:

Create a surface with EG pasted into it, NOT just a copy for we want the copied surface to be dynamically tied to the original. The down side here is duplicating a TIN surface will increasing the drawing size.

     1. Use the AutoCAD copy command to make a copy of the TIN Surface.

     2. From the Properties Rename it and set appropriate Style.

     3. Then use the Surface Edit command Raise/Lower to drop the elevation.

     4. Sample the new Surface to have it display in Profile View Grid.
