AutoCAD Civil 3D

[#1]

I am working on standard naming conventions for Civil 3D objects. Surfaces, alignments, profiles, etc. This is so everyone in the company will name their C3D objects with names that make sense to everyone. So far I have the surfaces done, but am unsure of where to go with the other types of objects. If anyone has a standard naming conventions that works well, I'd like to hear it. Here is what I have for surfaces:

1)      Surfaces

a)      EG - Existing grades surface

EG is used to identify any surface created from any type of existing data.

1. EG                                Finalized existing grade surface. This surface may be comprised of Aerial topo, Lidar contours, pasted survey surfaces, etc.
2. EG-Aerial                    Surface created from Aerial topo
3. EG-Lidar                     Surface created from Lidar data.

b)      FG - Finished grade surface

FG is used to identify any final grade surfaces

1. FG                              Finalized finished grade surface. This surface may be comprised of various pasted transitional grade surfaces or may simply be one single surface created using the grading tools.
2. FG-Lot-Name            Finished grade for a specific parcel. i.e. FG-Lot-1
3. FG-Septic                  Finished grade for a septic system.
4. FG-Basin-Name        Finished grade for a basin. i.e. FG-Basin-A
5. FG-Road-Name         Finished grade for a road. i.e. FG-Road-Brodhead

c)       SG - Survey grade surface

SG is used to identify any surface created from survey data.

1. SG-Road-Name         A surface created from surveyed points for a road. i.e. SG-Road-Brodhead
2. SG-Stream-Name     A surface created from surveyed points for a stream. i.e. SG-Stream-1
3. SG-River-Name         A surface created from surveyed points for a river. i.e. SG-River-Lehigh
4. SG-Wetland-Name    A surface created from surveyed points for a wetland. i.e. SG-Wetland-1
5. SG-Topo                     A surface created from surveyed points for any miscellaneous ground area.

d)      TG - Transitional grade surface

TG is used to identify any surface created to transition between other surfaces. These surfaces are only used to create topo for a feature and then the surface is added to an FG surface at a later point.

1. TG-Road-Name         A surface generated for a road or access road. i.e. TG-Road-Brodhead
2. TG-Trap-Name          A surface generated for a trap site. i.e. TG-Trap-Chase
3. TG-Basin-Name        A surface generated for a basin. i.e. TG-Basin-A

e)      VOL – Volume surface

VOL is used to identify any surface created as a volume surface to calculate the volume between two other surfaces and/or to display the cut/fill between the two surfaces. To make it easy to tell which surfaces the volume surface is doing the calculations for be sure to include the surface names in the name of the volume surface. See below for an example.

1. VOL-EG to FG            A surface created to calculate the volume between the EG surface and the FG surface.

Template looks good. Keep going

Agreed... good job

For a reconstruction job we will typically have at least two alignments for a street:

CL OLD STREET  the actual control line, stationing etc.

XCROWN OLD STREET alignment along the existing crown.  This will be profiled and superimposed so we get existing crown profile on control line stations

We may also superimpose profiles from the matchpoint, so I have used the names

XBS EAST

XBS WEST

 for the back of sidewalk alignment.  Typically I will give the same name to the profile too.

To my thinking, simply using EG and FG for surface object may confuse your folks because EG and FG could equally mean existing and finished profile. I'd suggest something like

EG-SURF and FG-SURF

EG-SURF-AERIAL

EG-SURF-LiDAR

EG-PROF and FG-PROF

Just to reply we use a similar practice and no one confuses an FG surface with an FG profile lol... not even sure how one could.

I agree. And I follow the EG FG convention from all the Autodesk tutorials. I like short names & long descriptions
