Civil 3D Surface Import Problem

[sduffin]

All,

I have had lots of experience with importing surfaces into Infraworks but I am stuck.  I created a model using model builder.  I opened up the Infraworks model in Civil 3D; I did some design work in SiteOps and exported to Civil 3D (as a LandXML, and as a Civil 3D drawing).  I try to import the proposed surface back into infraworks and I get the following error:

Failed to import the data.  See the details for further information.

I then tried many different ways to get the surface into the IW model but ultimately get the same error:

• Export surface from Civil 3D as a LandXML
• Export surface from Civil 3D as a DEM
• Tried opening the file in Infraworks from Civil 3D 2020 (IW is 2020)
• Tried opening the file from Infraworks in Civil 3D 2021
• Tried using a blank default template with absolutely nothing in it
• Ensured that Civil 3D is closed when opening in IW
• Exported from SiteOps as a LandXML
• Copied contours from exported Civil 3D drawing, created a new drawing, created a new Civil 3D surface
• Tried creating a brand new IW Model with nothing in it
• Updated patches for Civil 3D and Infraworks as delivered through the autodesk desktop manager

All these lead to the same error.

These are the things I can think of so far.  Any ideas on what may be causing IW to not be able to open the Civil 3D drawing and import the Civil 3D surface?  I have done this successfully many times that is why I am so baffled.  Attached are some of the CAD files, DEM files, LandXML files that I created.

Any help or ideas would be greatly appreciated!  Trying to finish off my model by tomorrow for a proposal that is due soon!  Thanks in advance!!

Hi @sduffin ,

I understand the basic issue is that you cannot import the LandXML file you created in Civil 3D (Proposed Surface.xml) into InfraWorks, correct?

I created a Model Builder model of your area of interest and loaded the file "Proposed Surface.xml" just fine:

Am I missing something?

Regards,
Karsten.

Thanks I was able to do the same.  I didn't try importing LandXML into new model builder model.  Not sure why it wouldn't work in my already built model, but I am good now.  Thanks for your help!

The LandXML file has a problem, in the category "RetWall"

The RetWallPnt do not follow trhe rule "northing easting elevation".

Thanks for digging into this!  I was able to get it to work by importing the LandXML into a new model builder model in IW.  Thanks for the response!
