Hi,
no need for Elements at all, the Category visibility is always attached to a given view, not to the model itself.
Revit 2018:
View.GetCategoryHidden(catId)
View.SetCategoryHidden(catId, bool hide)
Previous:
View.GetVisibility(catId)
View.SetVisibility(catId, bool show)
Note the unnecessary negation in 2018 :-(
You can create the needed ElementId just by using the BuiltInCategory in the constructor, "new ElementId(BuiltInCategory.OST_DetailComponents)".

I am looking to monitor file exports. In my addin application I am subscribing to both FileExporting and FileExported events. When running the addin, I am experiencing what looks to be an issue with the API.
In testing, file formats that trigger FileExportingEvent are: DWG, DXF, DGN, SAT, DWF, ADSK Building Site, gbXML, and IFC.
Those that don't trigger are: FBX and NWC.
I didn't test Family types, ODBC, Images and Animations, and Reports.
Looking at the documentation, ImportExportFileFormat enumeration list contains both FBX and NWC. This makes me believe that exporting to those formats should trigger the FileExport events. I also checked and they are not triggered with a SaveAs event.
Hi friend,
I need the code for obtaining the Id of the solid fill pattern. This is in order to set a filter view in revit project.
I followed the solution on this link below but there is no answer.
https://forums.autodesk.com/t5/revit-api-forum/solid-linepattern/td-p/4651067
Thanks for your reply..
The following code allows to solve this problem for the french Revit version 2016.
FillPatternElement fillPatternElement;
fillPatternElement = FillPatternElement.GetFillPatternElementByName(doc, FillPatternTarget.Drafting, "Uni");
filterSettings.SetProjectionFillPatternId(fillPatternElement.Id);
For another version of Revit use the translation of "Uni" in this version.
Revitalizer,
1. thank you for your help
2. the method format is:
bool View.GetVisibility(Category cat); // Revit 2015
so what i did is this:
bool isCategoryVisibile(Autodesk.Revit.DB.ViewPlan view)
{
ElementId eid = newElementId(BuiltInCategory.OST_DetailComponents);
Element element = m_doc.GetElement(eid);
return view.GetVisibility(element.Category);
}
but i get exception saids "Object reference not set to an instance of an object."
and if i may ask (with your permission?) i would like you also to know how to check if an Element is inVisibile by VG Filter and WorkSet
thanks again

How can I dissable space button for rotate example generic model.
I want for specified generic model wall hosted disable space button for rotate....can use arrow for dissable rotation but not don't dissable space button if you are in create mode for place generic model in project.
thx.
found this solution
privatebool isCategoryVisibile(Autodesk.Revit.DB.ViewPlan view)
{
Category category = doc.Settings.Categories.get_Item(BuiltInCategory.OST_DetailComponents);
return view.GetVisibility(category);
}
would be grateful if you reply my other questions.
What's the best way to get the material JPG, image stretch and size information through the API? I heard this was almost impossible to do and that it's making developer's work very hard to use Revit materials in external plugins like Otoy's Octane renderer.
https://render.otoy.com/forum/viewtopic.php?f=25&t=52667&p=318312#p318312
The API about the topic is very brief.
What are the preconditions for displaying of "deformation" state of an analytical model (surface) in Revit?
Does anyone have experience with the topic in general?
Hi,
the API gives you a language-independent approach, no need for string comparison at all.
For each FillPatternElement (can be got via FilteredElementCollector), you can get its FillPattern (GetFillPattern()).
FillPattern.IsSolidFill is the property you need to check.

Thanks Revitalizer.
I made a simple wall-mounted family using the "Generic Model wall based.rft" template. The family is just an extrusion attached to the top side of the wall as viewed in the Ref. Level
wall-mounted-box.rfa:
I want to import this wall-mounted-box.rfa into another Family (I will call this import.rfa) that also uses the "Generic Model wall based.rft" template. I want to place the box on the opposite side of the wall though, like the picture below. I can do this easily within the Revit UI. But I can't figure it out with the Revit API.
import.rfa:
Here is code showing the methods I've tested
string templateFileName =
@"C:\ProgramData\Autodesk\RAC 2016\Family Templates\English_I\Generic Model wall based.rft";
Document document = uiApplication.Application.NewFamilyDocument(templateFileName);
Family family;
using (Transaction transaction = new Transaction(document))
{
transaction.Start("Load Family");
document.LoadFamily(@"...\wall-mounted-box.rft", out family);
transaction.Commit();
}
FamilySymbol symbol = document.GetElement(family.GetFamilySymbolIds().First()) as FamilySymbol;
FilteredElementCollector wallCollector = new FilteredElementCollector(document);
Wall wall = wallCollector.OfClass(typeof(Wall)).FirstElement() as Wall;
using (Transaction transaction = new Transaction(document))
{
tx.Start("Instantiate Family");
symbol.Activate();
// METHOD 1: Default wall host
FamilyInstance familyInstance = document.FamilyCreate.NewFamilyInstance(new XYZ(0,0,0), symbol, wall, StructuralType.NonStructural);
// METHOD 2: try setting referenceDirection
document.FamilyCreate.NewFamilyInstance(new XYZ(0,0,0), symbol, new XYZ(0,-1,0), wall, StructuralType.NonStructural);
// METHOD 3: Try flipping the FamilyInstance
familyInstance.flipFacing();
// setup for METHOD 4/5
Reference reference = HostObjectUtils.GetSideFaces(wall, ShellLayerType.Interior).First();
// METHOD 4: use reference to face with method from this site
// http://adndevblog.typepad.com/aec/2015/06/revitapi-create-familyinstance-on-a-wall-face.html
document.FamilyCreate.NewFamilyInstance(reference, new XYZ(0, 0, 0), new XYZ(0, -1, 0), symbol);
// METHOD 5: Get the face to place on
// I just grabbed the index-2 face arbitrarily since this method doesn't work anyways
Options opt = new Options();
opt.ComputeReferences = true;
Face face = (wall.get_Geometry(opt).First() as Solid).Faces.get_Item(2);
document.FamilyCreate.NewFamilyInstance(face, new XYZ(0, 0, 0), new XYZ(0, -1, 0), symbol);
tx.Commit();
}
SaveAsOptions saveAsOptions = new SaveAsOptions();
saveAsOptions.OverwriteExistingFile = true;
document.SaveAs(@"...\import.rft", saveAsOptions);
METHOD 1 and METHOD 2 just places the box on the default side of the wall which is the top. Looks exactly like the wall-mounted-box.rfa picture.
METHOD 3 doesn't work because familyInstance.CanFlipFacing is false.
Here are the properties I grabbed from FamilyInstances I creating using the Revit UI.
default orientation on top of wall:
opposite orientation on bottom of wall:
METHOD 5 says "Family cannot be placed as hosted on an input face reference, because its FamilyPlacementType is not WorkPlaneBased"
METHOD 4 also says that FamilyPlacementType is not WorkPlaneBase.
How do I do this?
Hi everyone,
I wonder, is it possible to implement an auto-update functionality into the Revit add-in? I understand that the external application can run the code only when called from Revit, but if I place a button "Update add-in" on a ribbon, is there a way to implement it (download and rewrite itself)? If so, has anyone tried this successfully? Is there any code sample?
Thank you in advance,
Martin
I need use DUM for specified generic models that have special parameter.
But work only if I have only one typ of generic model ...other don't work..why?
var otCategoryFilter = new ElementCategoryFilter(BuiltInCategory.OST_GenericModel);
var familyInstanceFilter = new ElementClassFilter(typeof(FamilyInstance));
FilteredElementCollector eCollector = new FilteredElementCollector(doc);
eCollector.OfCategory(BuiltInCategory.OST_GenericModel);
String parameterName = "Type E";
ParameterValueProvider pvp;
FilterStringRuleEvaluator ele = new FilterStringEquals();
FilterStringRule frule;
UpdaterRegistry.RegisterUpdater(this, doc);
foreach (Element e in eCollector)
{
foreach (Parameter p in e.Parameters)
{
if (p.Definition.Name == parameterName)
{
ElementId idparametru = p.Id as ElementId;
pvp = new ParameterValueProvider(idparametru);
frule = new FilterStringRule(pvp, ele, "TEST", true);
epf = new ElementParameterFilter(frule);
}
else
{ }
}
}
LogicalAndFilter otInstanceFilter = new LogicalAndFilter(new List<ElementFilter> { otCategoryFilter, familyInstanceFilter, epf });
UpdaterRegistry.AddTrigger(m_updaterId, doc, otInstanceFilter, Element.GetChangeTypeElementAddition());
UpdaterRegistry.AddTrigger(m_updaterId, doc, otInstanceFilter, Element.GetChangeTypeGeometry());
Hi Jeremy,
I still have not received any advice as to how to get around not being able to duplicate dimension styles in 2018. I had hoped it would be fixed or workaround suggested before we released our product.
Best regards
Paul
Hi Matt
You haven't included this one, assuming it is a bug:

Paul
Hi
I think that your code needs to copy/paste the new .dll file to the correct location (something like Appdata\Roaming\Autodesk\Revit\Addin\XXXX) to do it. It should work with that.
Regards,
GM
Hi Paul,
2018.1 is out. Have you tested using that version?
If you're desperate for an API workaround, here's one way to do it:
It'll be slow, but it should work.
[Edit]
p.s. If you've not signed up to Revit Beta testing, then it would be worthwhile doing (to see if the issue persists there).
