Import HEC RAS Dialog Box

Use this dialog box to import an SDF file that was exported from the HEC-RAS software program.

Workflow: To Export and Import HEC-RAS Data

Reach Alignment

Site For Reach Alignment

Specifies the site into which the stream alignment is imported.

Note: The stream alignment is imported into the drawing only if an alignment of the same name does not already exist in the site you specify. Existing alignments of the same name and site are not overwritten. LINE objects that represent the sections are only imported if the alignment is imported.

Style For Reach Alignment

Specifies the style to use for the stream alignment when it is imported.

Alignment Label Style Set

Specifies the label set to use for the stream alignment when it is imported.

Profile Style

Specifies the profile style to use for imported profiles.

Profile Label Style Set

Specifies the label style set to use for imported profiles.

SDF To Import

File

Specifies the SDF file that was exported from the HEC-RAS software application. Click the browse button to select the file. For more information, see To Import Data into and Export Data from HEC-RAS Software.

Stream

Specifies which stream within the SDF file to import. When you select a stream, the number of profiles and sections that exist for that stream are shown in the dialog box.

• The profiles are imported as Autodesk Civil 3D profile objects. You must create a profile view in the drawing to view them.
  Note: Existing profiles of the same name inside the same alignment will be overwritten. This behavior enables you to perform multiple iterations within the HEC-RAS application without having to manually delete profiles in Autodesk Civil 3D when you bring in updated data.
• The section data is imported as LINE objects along the alignment. These lines show the top water surface at each section. They are created on layers using the convention <alignment name> - <profile name>. The section lines are imported only if the alignment is imported.

Import

Imports the specified SDF file.
