remove nwd from nwf. Save nwf with clash tests.

[Evgueny]

Hi dears.
I have a problem with remove nwd files from nwf using api functions.
I try to use this function:

            Autodesk.Navisworks.Api.Controls.DocumentControl doccontrol = new DocumentControl();
            Document doc;
            doc = doccontrol.Document;
            doc.TryOpenFile("filename")

            Model item = doc.Models.First;
            doc.Models.InternalRemove(item);

Error message:

System.NotSupportedException: Use Document.RemoveFile
   в Autodesk.Navisworks.Api.DocumentParts.DocumentModels.InternalRemove(Model item)

But i'm not find this function. May be there is Com function?

And second problem. Most importantly.

If my nwf file contains a clash test then after the save clash test is disappears.
(doccontrol.Document.TrySaveFile("filename",DocumentFileVersion.Navisworks2012))

How to save document with clash tests?
Thank you! Regards! Evgeny Fedorov.

ps. I know about restriction of clash when using api function. But maybe there is a way out of the situation.

As to clash test, do you mean the clash test info will disappear if saving by API? Does this occur with a plugin or a control based app?

Hi, Xiaodong Liang.
Yes clash test info will disappear if saving by API occur with a control based app.

Hi,

Sorry I was not able to get back. I can reproduce this problem and logged this issue as NW-48310 - Control based app cleans up Clash Test when saving. Sorry for the issue.
