I am trying to export a 3d Revit model family image for a thumbnail using the Revit API. I have tried to turn on the model edges so that they are displayed as darker lines and I have tried to turn on anti-aliasing so that lines are smoothed. I realise it is probably hopeless to switch on the shadows as this option isn't available in a family doc.
I have exhausted all the image export options properties. The code below has the export image options and the enumerated Revit API properties I have managed to set so far.
if (view3D != null)
var graphicDisplayOptions = view3D.get_Parameter(BuiltInParameter.MODEL_GRAPHICS_STYLE);
// Settings for shaded with edges
var detailLevelOptions = view3D.get_Parameter(BuiltInParameter.VIEW_DETAIL_LEVEL);
//Settings for view detail, 3 = fine, 2=med, 1=coarse
var ieo = new ImageExportOptions
//Export image file configuration settings
FilePath = ImageFamModelFileName,
FitDirection = FitDirectionType.Horizontal,
HLRandWFViewsFileType = ImageFileType.BMP,
ShadowViewsFileType = ImageFileType.BMP,
ImageResolution = ImageResolution.DPI_600,
ShouldCreateWebSite = false
At this blog post there is a test case for Family documents and the View, please take a look. Below is a piece of it.
#if !VERSION2014 var direction = new XYZ(-1, 1, -1); var view3D = doc.IsFamilyDocument ? doc.FamilyCreate.NewView3D(direction) : doc.Create.NewView3D(direction); #else var collector = new FilteredElementCollector( doc ); var viewFamilyType = collector .OfClass( typeof( ViewFamilyType ) ) .OfType<ViewFamilyType>() .FirstOrDefault( x => x.ViewFamily == ViewFamily.ThreeDimensional ); var view3D = ( viewFamilyType != null ) ? View3D.CreateIsometric( doc, viewFamilyType.Id ) : null; #endif // VERSION2014
