Help - acad proxy entities - data extract

[Anonymous]

Hello!

So I am using autocad Civil 3D 2012 and I have a dwg that has some spot elevations that are stuck as proxy entities. 

My end goal is to create an ascii file including the x,y,z coordinates of these spots. 

I realize the only easy way to do this is to have the author of the dwg save it back to 2012, but I can't do this. 

I have tried listing the spots in TrueVIew and I can see that they are cogo points and it shows all the information I need in the command prompt but I need to export it somehow. 

If anyone has experience with this please let me know!

Thank you in advance!

Hi @Anonymous, I downloaded your drawing but it is not information on it...

Hi!

Thank you for replying, I have attached the correct dwg now.

Here you go @Anonymous, the attached file is txt file format PNEZD comma delimited

That is perfect! Thank you

How in the world did you do that?

I am using C3D 2018 so I can open anything older than that.

1. Rigthclick on points from your Prospector tree and select export points

2. Then choose a file format from the pulldown list, give it a name, a location and select a file type to export

It is my pleasure to help 😉

Oh I see. This is great for now, but I still need to be able to do it myself in the 2012 version. 

Thank you for you help!

You can't do a Data Extraction from Proxy objects to get x,y,z location

1. So the next time ask whoever sent you the file to do a _AecExportToAutoCAD2010

2. That will show all the COGO points as block of reference with x,y,z

3. Create a surface from them (Surface -> Definition -> add drawing objects -> blocks)

4. Change the surface style to show the surface points

5. Use this command to extract the points from the surface _AeccSurfaceExtractObjects

This will create regular ACAD points that you can do a DATAEXTRACTION or you can create COGO from.

Is a long workflow but that is what I could come out with for now...
