Civil 3D and Survey

Autodesk Civil 3D is a civil engineering design and survey product that
sits on the AutoCAD software platform and has been around for several years. It is most commonly used for the design of land
development sites as well as Road and Rail design and supports Building Information Modeling (BIM) workflows.

Autodesk Civil 3D has the ability
to create such things as:

  •  Existing ground model & surface
  •  Design model & surface
  •  Pipe networks
  •  Longsections
  •  Cross Sections
  •  Quantity Analysis

Civil 3D is not only being used by civil engineers but also by
surveyors as the software has a dedicated survey interface. This interface can
be used to setup standards for interpreting the information from the survey equipment
while importing the field data straight into Civil 3D. If setup correctly Civil
3D will recreate the survey automatically drawing lines and breaklines between
points, adding symbology and traverse lines. As stated above, Civil 3D can perform quantity
analysis which is ideal for cut and fill calculations by using surface models
such as existing ground vs excavated level vs design level. Civil 3D is built on a GIS engine (MAP 3D) so this allows for the import and export of GIS information and the ability to assign NZ coordinate systems.
Creating land parcels is made easy with the Parcel Creation wizard
and editing tools.
Point clouds can also be imported, Civil 3D has the capacity
to handle a large amount of data and provides various tools for exploring and
interpreting the point cloud.
Surveyors and contractors often require set-out data of the design or surface when on-site, this can sometimes be quite time consuming and difficult
getting the data into a format that the surveyor or contractor can use (setout coordinates). With the progression
of technology Civil 3D can make this process easier by exporting 3D
models in a format that is suitable so that it can be viewed and used on
site using mobile devices, tablets and GPS.

To accompany the features I have discussed above, there are some really good add-ons available for Civil 3D, such
  • Data Extension for 12d – Import/Export 12d data.
  •  Civil Engineering Data Translator – Exchange civil
    engineering data between other software applications.
  •  Extension for Civil View 2015 – Export civil
    engineering data to 3ds Max.
  •  Import-Export Extension for GENIO.
  •  LINZ Survey Utility – interact with LINZ
    Landonline system.
  •  Rail Layout Module – place and edit track layout
  •  Shared Reference Point – Create a shared
    reference point with Revit.
  •  Productivity Pack:
 Coordinate Geometry Editor – Enter, edit and
analyse 2D traverse data.
 Open Infraworks Model – opens Infraworks models
in Civil 3D.
 Create AutoCAD 3D Solids – Create 3D solids for
surfaces and pipe networks.
  • Geotechnics Module – Bring geotechnical data
    straight into Civil3D.
  • Bridge Modeler – Create concrete bridges.

These add-ons are only available to Maintenance Subscription
or Desktop Subscription users.

Civil 3D works well with Autodesk Infraworks 360, the import/export between both have been streamlined to allow quicker and smoother collaboration. A concept design can be output from Infraworks 360 and brought into Civil 3D for more detailed work to be done. Any changes made to the model can be reflected in either Infraworks 360 or Civil 3D.
