Topic: Saving down with Objectdbx

[OcCad]

I'm modifying multiple drawing with odbx but some files were becoming unreadable for clients. Normally I save down to 2004 from 2008 but in odbx the default saveas seems to be 2007. How do I do a saveas savedown to 2004? Or convert to 2004?

Have you tried this.
It will convert multiple files.

Thats the thing though. i dont want to have to use dwgconvert. I would rather do it in the lisp. Right now the routine is causing the problem by vla-saveas to 2007. is there a way to tell it to save to 2004 version?

[CAB]

Bad news I'm afraid.

I dont understand. that post says the vla-save method doesnt work in odbx. But I'm looking to use vla-saveas but to an older format

True, you can't.

AKAIK ... You can't specify the format. The SaveAs method for documents opened via ObjectDBX takes two arguments, the first (mandatory) is a string representing the file path and name. The second (optional) is a variant allowing one to encrypt and digitally sign the drawing. I personally haven't used the latter and can't say I'm an advocate.

Sorry to confirm the bad news.

Do you have to use ObjectDBX? Are you processing hundreds/thousands of drawings?

I'm sure you have your reasons for not using dwgconvert, but I can't immediately think of one ... care to share the reasons ?

Don’t know if this will help you but here is an ARX routine that might do the trick.

Code: [Select]

(saveas2004 "c:\\1.dwg" "c:\\2.dwg")
(saveas2000 "c:\\1.dwg" "c:\\2.dwg")

Daniel,

That's interesting. Where did it come from? Google search finds no mention of it elsewhere.

A few quick tests indicate it *may* be a solution for saving down an ODBX document. After the document is released, I think you would have to give the file a unique saveas name. Then delete the original/source file and rename the new file the same as the original. IOW, it does not allow this (saveas2000 "c:\\example.dwg" "c:\\example.dwg").

...Where did it come from?....

I just wrote it,
 my tests also show that it can’t be the same filename 

[MP]

Nice, I'll have to try that Daniel. Like Joe said, where did it come from? Is the source code available? I'd be wary of building a solution around it without knowing something about it's origins and future. Nonetheless has promise.

Bah, ya snuck in as I was posting, I'll leave it verbatim; peace.

Thanks Daniel, that's be great.

I'm modifying multiple drawing with odbx but some files were becoming unreadable for clients. Normally I save down to 2004 from 2008 but in odbx the default saveas seems to be 2007. How do I do a saveas savedown to 2004? Or convert to 2004?

AutoCAD 2008 has a new command called AECTOACAD that will allow you to save in a lower version (back to R14).  Might be of some use?!?

[It's Alive!]

added (saveasR14  "c:\\1.dwg" "c:\\2.dwg")

Very generous Daniel, thanks again.

Kerry, Though my response seems a little late (and by the way thanks, daniel!) the reason I would prefer not use dwgconvert is that it would take me just as much time to run a batch version of my lisp that will save as 2004 as it would to run the much quicker odbx and then use dwgconvert which is not that fast.

And did everyone just completely ignore Matt W's response. I did not know that about 2008. I will have to look into this.

Cannot use command calls with an ODBX document.

[Joe Burke]

Daniel,

I'm not familiar with the code you posted.

I'm wondering what's the mechanism involved? Specifically, is it exactly the same as what happens when Options > Open and Save tab is set save down to a previous file format?

Looking forward to your post in Show your stuff.

Thanks

Joe's right.  I just threw that out as an option, figuring you were more focused on ODBX.  You'd still have to actually open each drawing, call the command, wash, rinse, repeat.  Like I said, I just threw it out as an option.

(That command may have been introduced in 2007, for what it's worth)

[Joe Burke]

Matt,

If the document involved in not an ODBX doc, the SaveAs method allows a choice of file format.

ODBX would be more powerful if it offered the same option.

I am not sure what Autodesk does internally, but does act different that what I am doing. All I am doing is opening the database and saving it down through the method provided in the ARX SDK, have  look at acdbSaveAs2004()  and AcDbDatabase::saveAs(). In the ARX docs
