To Create a Surface

To create a surface, the drawing file must have Civil 3D settings defined. Such a drawing file can be created by either using the INSERT command to insert a Civil template into a Utility Design drawing, or by opening a Civil template and importing a Utility Design industry model, using the AUDINDUSTRYMODELADD command.

You can create a civil surface from points, lines, or blocks, and then inserted Utility Design features can get elevations from the surface. The command MAPIMPORT can be used for generating point entities from survey or GPS point data.

To configure the styles and settings for surfaces, see Civil Options.

To create a surface by inserting a Civil template into a Utility Design drawing

1. Open a Utility Design template.
2. Use the INSERT command to insert a Civil template.
3. Use the MAPIMPORT command to import survey or GPS point data.
4. Click HomeProject Area panelBase MapCreate Surface.
5. Select the points, lines or blocks to define surface

Here is an alternative workflow.

To create a surface by importing a Utility Design industry model into a Civil template

1. Open a Civil template in Utility Design.
2. Use the AUDINDUSTRYMODELADD command to add a Utility Design industry model.
3. Use the MAPIMPORT command to import survey or GPS point data.
4. Click HomeProject Area panelBase MapCreate Surface.
5. Select the points, lines or blocks to define surface

You can also use the AUDSURFACEIMX command to import an InfraWorks .imx file and create a corresponding Civil 3D surface.
