问题 I have a bunch of ramps that I would like to know the begin and end points of (and in case of multiple begin/end points I would like to know how they connect). I currently get these as List<TransitionPoint> ret = new List<TransitionPoint>(); FilteredElementCollector collector = new FilteredElementCollector(doc); ICollection<Element> ramps = collector.OfCategory(BuiltInCategory.OST_Ramps).ToElements(); foreach (var ramp in ramps) { //what goes here? } These ramps contain the following

It seems Revit itself manages the unhandled expections and shows its own crash dialog. What should I do to catch all unhandled exceptions in revit addin before Revit cathes them?

问题 I'm trying to set a view title to show up on a Revit project using the Revit API however I can't figure out how to access it.

问题 When loading Revit models which are aligned by shared coordinates, the models does not align in Forge Viewer with globallOffset settings. The loadModel with placementTransform option seems to be viable, but the shared coordinates data is not made available until after the model is loaded, via viewer.model.getDocumentNode().getAecModelData().refPointTransformation earliest I have the model data is inside the onLoadModelSuccess which is too late to feed into the load options, and will require

问题 I'm trying to pass a value(an element id) from a WinForm back to the Command.cs file but I'm getting an error: System.NullReferenceException: Object reference not set to an instance of an object. at BatchSheetMaker.Command.Execute(ExternalCommandData commandData, String& message, ElementSet elements) I'm following the youtube tutorial here and it seems fairly easy and straight forward but passing back to the Command.cs is another layer of complexity. I have the Command.cs code wrapped in a
