The Import option allows one, or more, Phases from within an InfoDrainage design to be imported into the Civil 3D® design.
This will create a Pipe Network for each phase imported that will contain the Closed sections and Manholes. Where it is not possible to represent elements within the InfoDrainage design within the Pipe Network, i.e. open channels, or Stormwater controls, they will be created as alternative entities. Please see Representation of Unsupported Data for more information.
There is a wizard to guide the user through the import process. The wizard presents the user with a sequence of dialog boxes that lead the user through a series of well-defined steps. To progress through the steps in the wizard, press the Next button. To return to a previously completed step, press the Previous button.
Step 1: File Selection
This step allows the selection of the file to be imported from. Pressing the select button invokes a file selection dialog to allow easy location of the file/folder.
Only InfoDrainage files from the currently installed version or previous versions can be loaded. An attempt to load an InfoDrainage file from a newer version will result in a warning message.
Step 2: Phase and Surfaces Selection
This step allows the selection of phases and surfaces that will be imported from InfoDrainage. Each selected phase will be imported as a Pipe Network in the Civil 3D® design.
There are three surface import options that can be selected on the Part Mapping Manager during the import from InfoDrainage.
Use Existing Civil 3D® surface - The existing network surface will be used. The import will not modify the surface.
Load Surface from Phase - A surface will be created from the InfoDrainage phase surface vertices and breaklines.
Phases in an InfoDrainage design must be valid in order for the import to be successful. Invalid phases will be disabled on the Phase Selection page.
Step(s) 3 till end: Parts Mapping
For each selected phase there will be a parts mapping step, which allows the mapping of InfoDrainage types to Civil 3D® part types. See Parts Mapping for more details.
When the step is initially shown, the phase to import is examined. If any network parts are discovered that have no current mappings, a blank entry will be added for that part type.
When Next or Finish is pressed at each parts mapping step the given parts mappings will be validated. Any invalid properties will be flagged and will need correcting before the step can be completed.
Civil 3D® does not allow the following characters \<>/:;?*|,="" and these will be removed in the names of entities if found.
The following table lists some common Import Warnings you may encounter when importing a InfoDrainage file.
|"Connection has vertical sides which is not supported in Civil 3D®. The top Area has been increased slightly to avoid this."|
|"Stormwater Control has an overhang which is not supported in Civil 3D®. The data has been capped where the Area increases with depth after decreasing with depth."|
|"Stormwater Control has vertical sides which is not supported in Civil 3D®. The top Area has been increased slightly to avoid this."|
|"Duplicate name detected original name has been changed to new name"|
|"The number of barrels specified means that pipes do not all fit inside the manhole. Pipes have been overlaid to maintain connectivity but a larger manhole may be needed."|
Removal of Items
If an InfoDrainage phase is re-imported, it will replace the previously imported network. Any items that were deleted from the InfoDrainage phase since the previous import will be removed from the Civil3D® design. Any items that have been added to the network using Civil 3D® will not be deleted, as they were not a part of the previous import.
Any locked layers will be temporarily unlocked during import to grab the relevant data out and then re-locked when finished.
