Hi Vijay,

I am not sure I understand the request. Is this about the thumbnail image for an idw file? It is captured from the active sheet based on Front view. Do you want it to be looked at from a different angle?

Many thanks!

Hello Johnson Shiue,

   Thank you for your response.

    Actually my requirement is to generate Thumbnails for all document types in structure files.

   I got some piece of code from Online articles. But in below code I am able to generate Thumbnails only Part and Assemblies. I am not able to generate the Drawings(IDW) files.

Can you please suggest how to generate Thumbnails for Drawings(IDW) files.

string fileNameImage = "thumbnail.bmp";
string documentFolder = System.IO.Path.GetDirectoryName(document.FullFileName);
string imageFilename = System.IO.Path.Combine(documentFolder, fileNameImage);
if (document.DocumentType == DocumentTypeEnum.kPartDocumentObject)
{

Camera camera = m_server.TransientObjects.CreateCamera();
camera.SceneObject = (document as PartDocument).ComponentDefinition;
camera.ViewOrientationType = ViewOrientationTypeEnum.kIsoTopRightViewOrientation;
camera.Fit();
camera.ApplyWithoutTransition();
Color backgroundColor = m_server.TransientObjects.CreateColor(0xEC, 0xEC, 0xEC, 0.0);
camera.SaveAsBitmap(imageFilename, 512, 512, backgroundColor, backgroundColor);
}
if (document.DocumentType == DocumentTypeEnum.kAssemblyDocumentObject)
{
Camera camera = m_server.TransientObjects.CreateCamera();
camera.SceneObject = (document as AssemblyDocument).ComponentDefinition;
camera.ViewOrientationType = ViewOrientationTypeEnum.kIsoTopRightViewOrientation;
camera.Fit();
camera.ApplyWithoutTransition();
Color backgroundColor = m_server.TransientObjects.CreateColor(0xEC, 0xEC, 0xEC, 0.0);
camera.SaveAsBitmap(imageFilename, 512, 512, backgroundColor, backgroundColor);
}

You can try it like this:

string fileNameImage = "thumbnail.bmp";
string documentFolder = System.IO.Path.GetDirectoryName(document.FullFileName);
string imageFilename = System.IO.Path.Combine(documentFolder, fileNameImage);
Color backgroundColor = m_server.TransientObjects.CreateColor(0xEC, 0xEC, 0xEC, 0.0);
if (document.DocumentType == DocumentTypeEnum.kPartDocumentObject)
{

    Camera camera = m_server.TransientObjects.CreateCamera();
    camera.SceneObject = (document as PartDocument).ComponentDefinition;
    camera.ViewOrientationType = ViewOrientationTypeEnum.kIsoTopRightViewOrientation;
    camera.Fit();
    camera.ApplyWithoutTransition();                
    camera.SaveAsBitmap(imageFilename, 512, 512, backgroundColor, backgroundColor);
}
if (document.DocumentType == DocumentTypeEnum.kAssemblyDocumentObject)
{
    Camera camera = m_server.TransientObjects.CreateCamera();
    camera.SceneObject = (document as AssemblyDocument).ComponentDefinition;
    camera.ViewOrientationType = ViewOrientationTypeEnum.kIsoTopRightViewOrientation;
    camera.Fit();
    camera.ApplyWithoutTransition();
    camera.SaveAsBitmap(imageFilename, 512, 512, backgroundColor, backgroundColor);
}
if (document.DocumentType == DocumentTypeEnum.kDrawingDocumentObject)
{
    // for this to work the document needs to be the active document.
    document.Activate();

    Inventor.View view = ThisApplication.ActiveView;                
    Camera camera = view.Camera;
    camera.Fit();
    camera.ApplyWithoutTransition();

    camera.SaveAsBitmap(imageFilename, 512, 512, backgroundColor, backgroundColor);
}

 This is the most basic way that I know. It leaves you with some strange borders. Have a look at this post if you want to remove those (partially).
