Proxy Entities

[krisj89]

I have a drawing that was started in Civil 3D 2011. When i try to open it in Civil 3D 2010, i get a message that staes: "This drawing was created with a newer version of Civil 3D. All entities created by Civil 3D withih the drawing are in a proxy state. Additionally, all commands, settings, and displays of Civil 3D are disabled for this drawing."

I don't want these objects to be in a proxy state!! I don't want my commands, settings, and displays to be disabled!!

Please help!!

Opening/using an 2011 version in 2010 has discussion a lot in here.. If you need to work on it in 2010 then your option is export to LandXml from 2011 and import into 2010.

Civil 3D drawings are not backwards compatible. Civil 3D 2011 drawings will have objects in them that Civil 3D 2010 cannot interpret, so all objects are put into a proxy state to prevent issues. Once a drawing is created in Civil 3D 2011, it has to stay in 2011. 

The workaround for this is to export your data to LandXML as Murph suggested, and then export your drawing to AutoCAD. You can then open the drawing with the linework and import your data via LandXML into your 2010 drawing.

Just keep in mind, LandXML is far from perfect as Autodesk loves to simplify their response by saying "export to autocad and use LandXML for your design".  The alignments you get are not as easily edited as the original alignments would be (elements all become fixed), existing groud profiles are static so they will need to be recut, you can't use LandXML to export your feature lines, and 3d feature lines you had with varying elevations will be drop the arcs they previously had, etc, etc, etc.

Don't get me wrong if you don't need to make any edits and want to be able to do things like add notes and labels LandXML works but if you want to actually use your design data you will end up recreating much of it.  The need for this data to move smoothly between dwg files THAT USE THE SAME DWG VERSION is something that has not been addressed for as long as civil 3d has been around and whenever we mention the need the over simplification of LandXML and export to DWG gets presented as a solution.

Hope it helps to know others feel your pain on this, the solution I tell our staff is you can go forward but going back means you are recreating much of your work if you need to edit it.

Can a "straight" AutoCAD 2011 drawing (without any Civil 3d objects in the drawing) be saved to an earlier version and then be opened & used in as 2009 Civil 3d file?

WHAT A JOKE!

Oh and look 2012 is out and it's got all these great new features.....bull****!

Fix what you have and then tout the new stuff.

Oh and I can "Save As", oh but wait it alreadys saves as a 2010 drawing, thats weird.....but I can't even see my linework, what a piece of junk, it does all these great things

No, well, yes & no.  None of the C3d enties will work.
