Delete Civil 3D Elements in Exported to Autocad Files

[Anonymous]

Hi,

My CAD manager asked me if I know how to solve long know problem of deleting elements of Civil 3D out of export to Autocad files.

He is saying that every time he is doing purge and close the drawing things are comming back. As an example materials .

I'm agree that it's unnesesary weight for files and a server after all.

So is there a more proper way of doing export?

Thank you,

Vasily

Doesn't seem to do that for me. When I epxorted the file, opened, purged, there was nothing to be purged. I did this with the Align-7C.dwg from the tutorials. Can you try it with that file and see if you get the same results?

Doesn't work

Before Purge

After purge

After saving and reopening

If you are loading XREFs then yes - materials (and plot styles, and a few other things) will propagate from the XREF into the host drawing.  There's nothing you can do about it, short of removing the offending data from the XREF itself (which might not be desirable).

Fare enough but in my case I don't do referensing and still get materials back.
Single file was purged and saved and just opened after that.

How are you exporting the file? If you're using e-transmit, you can choose in the setup which objects are exported.

We had noticed a lot of 'artifacts' that hang around even after an export. Our solution has been to freeze the layers we don't want and wblock the visible elements out to a fresh new file. Seems the only way we can get rid of them.

I have gotten good results when I export a civil3d file to DXF Version 2000, then open the Dxf and purge the file, then save-as to the DWG format. Clears all hidden objects.
