I know this may sound similar to other questions about the same topic but I didn't find a good solution.
My objective is to create a function which will get the all the elements in all Linked models Visible in a 3D view.
Afterwards, it should copy all the elements to the active document from which we called this function.
I can't figure out how to get the elements from the linked models effectively, I tried using the Bounding Box Filter
but it doesn't return any results, just some other 3D views, it worked for me before when applied to non-linked
models but doesn't give me the same result here:
{
var activeView = ActiveDoc.ActiveView;
var activeBBox = activeView.get_BoundingBox(null);
var activeOutline = new Outline(activeBBox.Min, activeBBox.Max);
var result = new List<Element>();
foreach (var doc in Documents)
{
var collector = new FilteredElementCollector(doc)
.WherePasses(new BoundingBoxIntersectsFilter(activeOutline));
result.AddRange(collector.ToElements().ToList());
}
}
I was able to solve this using ElementIntersectsSolidFilter, with some help from this post:
https://forums.autodesk.com/t5/revit-api-forum/create-solid-from-boundingbox/td-p/6330376
but I really didn't want to use this slow filter, any way this can be solved with a quick filter ?
var activeView = ActiveDoc.ActiveView as View3D;
if(activeView == null) { return; }
var activeSolid = solidBoundingBox(activeView.GetSectionBox());
var result = new List<Element>();
foreach (var doc in Documents)
{
var collector = new FilteredElementCollector(doc)
.WherePasses(new ElementIntersectsSolidFilter(activeSolid));
Transaction targetTrans = new Transaction(ActiveDoc);
CopyPasteOptions copyOptions = new CopyPasteOptions();
copyOptions.SetDuplicateTypeNamesHandler(new CopyUseDestinationHandler());
targetTrans.Start("Copy and paste linked familys");
ElementTransformUtils.CopyElements(doc, collector.ToElementIds(), ActiveDoc, null, copyOptions);
ActiveDoc.Regenerate();
targetTrans.Commit();
}
Thanks.
