referenceWithContext showing as null although elements intersects?
I am having walls they are making closed loop .want to place the family instances with fixed distance in that.Using ReferenceIntersector i am trying. I got ray direction but in referenceWithContext value is remain null so not able to proceed further.
Reference oref =uiApp.ActiveUIDocument.Selection.PickObject(Autodesk.Revit.UI.Selection.ObjectType.Element);
Element ele = activeDoc.GetElement(oref);
LocationCurve ocurve = ele.Location as LocationCurve;
XYZ startPoint = ocurve.Curve.GetEndPoint(0);
XYZ endPoint = ocurve.Curve.GetEndPoint(1);
XYZ rayDirection = endPoint.Subtract(startPoint).Normalize();
List<BuiltInCategory> builtInCats = new List<BuiltInCategory>();
builtInCats.Add(BuiltInCategory.OST_Walls);
builtInCats.Add(BuiltInCategory.OST_GenericModel);
ElementMulticategoryFilter intersectFilter = new ElementMulticategoryFilter(builtInCats);
FilteredElementCollector collector1 = new FilteredElementCollector(activeDoc);
Func<View3D, bool> isNotTemplate = v3 => !(v3.IsTemplate);
View3D view3D = collector1.OfClass(typeof(View3D)).Cast<View3D>().First<View3D>(isNotTemplate);
ReferenceIntersector refIntersector = new ReferenceIntersector(intersectFilter, FindReferenceTarget.Element, view3D);
refIntersector.FindReferencesInRevitLinks = true;
it is working fine upto this line
ReferenceWithContext referenceWithContext = refIntersector.FindNearest(startPoint, rayDirection);
but here it is showing null.
After getting this I want to place family with fixed distance apart .

Re: How to Get floor's Core Thickness
Hi
Is your floor is Floor:Architectural or Floor:Structural?
If your Floor is structural and you use
BuiltInParameter.STRUCTURAL_FLOOR_CORE_THICKNESS
then you will get the Core thickness of the floor
otherwise
for architectural floor it will be always 0.

Issue while reading Data using "ScheduleDataParser"
Hi,
while reading schedules from a Revit file, but a schedule contains a parameter called function 2 times. I just export it to a text file and try to read using ScheduleDataParser .
ScheduleDataParser parser = new ScheduleDataParser(Path.Combine(_export_folder_name, FileName + _ext));
But it throw exception like "A column named 'Function' already belongs to this DataTable."
can you help me to solve the issue or give an alternative for this.
Thanks in Advance.

Re: Addin WPF Windows Renders As Expected In 2018, not 2019
Dear Chris,
I didn't find potential Revit API which will result in this issue.
The problem here is some assemblies are not loaded successfully, I guess this is why the window rendering doesn't work; you may refer to these page on how to load assemblies properly, hope it's helpful:

C++ : can we do everything?
Hello
Before to begin write any programs in c++ for Revit, I want to be sure that we can to do everything with this language.
Are there c ++ restrictions?
I can read some things were not possible...
Exemple :
-Manage color choices
-Access the formulas of a nomenclature;
-No JIG as in AutoCAD;
-You can not create project settings, only shared settings;
-You can not rename a project parameter;
-You can not create / edit a label in a label;
-You can not create custom object snaps;
-You can not overload the drawing / behavior of an object as you can with AutoCAD;
-No transient graphics like AutoCAD or Inventor (you can do some things with AVF, but it's limited);
-We can not do much with the variants;
-Decompose a CAD import symbol (DWG for example). However, we can find the geometry contained in the symbol and recreate elements but it's a lot of work;
-Attach a linked file;
-Modify an in-situ family;
-Select a point in 3D (you can only select a point on the active construction plane).
Thanks

Re: Distance point to solid
Hi list,
Unfortunately the Solid-Intersection-Approach does not work as expected, since the call to
BooleanOperationsUtils.ExecuteBooleanOperation(sphere, theSolid, BooleanOperationsType.Difference);
can lead to an exception:
"Failed to perform the Boolean operation for the two solids. This may be due to geometric inaccuracies in the solids, such as slightly misaligned faces or edges. If so, eliminating the inaccuracies by making sure the solids are accurately aligned may solve the problem. This also may be due to one or both solids having complexities such as more than two faces geometrically meeting along a single edge, or two coincident edges, etc. Eliminating such conditions, or performing a sequence of Boolean operations in an order that avoids such conditions, may solve the problem. "
It is not really clear to me, why this exception is thrown, because in the case I catch it, no complicated solids were present (just one solid consisting of two rectangular boxed and the sphere). The sphere is defined straight forward:
XYZ profileArcPlus = center + new XYZ(0, 0, radius);
XYZ profileArcMid = center + new XYZ(radius, 0, 0);
XYZ profileArcMinus = center - new XYZ(0, 0, radius);
Frame frame = new Frame(center, XYZ.BasisX, XYZ.BasisY, XYZ.BasisZ);
List<Curve> profile = new List<Curve>();
profile.Add(Line.CreateBound(profileArcPlus, profileArcMinus));
profile.Add(Arc.Create(profileArcMinus, profileArcPlus, profileArcMid));
CurveLoop curveLoop = CurveLoop.Create(profile);
SolidOptions options = new SolidOptions(ElementId.InvalidElementId,
ElementId.InvalidElementId);
Solid sphere = GeometryCreationUtilities.CreateRevolvedGeometry(frame, new CurveLoop[] { curveLoop }, 0, 2 * Math.PI, options);

Re: Changing the Font of schedule headers with SetCellStyle
Dear David,
Can you provide a reproducible case for it? I didn't find problematic code in your sample code.
In order to explore this matter further, we will need to provide a minimal reproducible case for the development team to analyse in depth.
In order to understand exactly what you mean and be able to research possible reasons for the discrepancy between the observed and expected behaviour, they require:
· A short exact description of what you are trying to achieve.
· The behavior you observe versus what you expect, and why this is a problem.
· A complete yet minimal Revit sample model to run a test in.
· A complete yet minimal macro embedded in the sample model or Visual Studio solution with add-in manifest that can be compiled, loaded, run and debugged with a single click to analyse its behavior live in the sample model.
· Detailed step-by-step instructions for reproducing the issue, e.g. which element to pick, what command to launch etc.

Re: referenceWithContext showing as null although elements intersects?
Thank you for reply.
It is now working when draw walls in existing project.
But Now having another isssue. When reference intersector is use
ReferenceWithContext referenceWithContext = refIntersector.FindNearest(startPoint, rayDirection);
Reference reference = referenceWithContext.GetReference();
XYZ intersection = reference.GlobalPoint;
Not able allocate correct intersection
when i place family instance at intersection it is placed on the wall itself (where i have given the reference) although their is no intersection on this point.

Re: Units on the elements, that conform the assets of materials
Dear Javier,
I looked at the built-in Revit materials in the material browser.
Looking at the standard built-in Concrete material, I see that it has a physical description saying, "Default Concrete f'c=3.5 ksi".
I just published a new version of RevitLookup that enables the snooping of appearance assets:
- https://github.com/jeremytammik/RevitLookup
- https://github.com/jeremytammik/RevitLookup/releases/tag/2019.0.0.10
Using that version, I find that the description of the built-in Concrete material is located in the 'Description' parameter along the following path:
- Snoop DB > Material > Concrete 216216 > StructuralAssetId > Parameters > Description.
I hope that this new version of RevitLookup will enable you to find the corresponding paths for the other values you are after as well.
Best regards,
Jeremy

Re: Enhanced DWG Exporter for Revit API
Dear Kevin,
Thank you for your query.
I looked at the main web page describing the BIM Interoperability Tools and see the Enhanced DWG Exporter you mentioned:
- https://www.autodesk.com/solutions/bim/hub/bim-interoperability
- http://www.biminteroperabilitytools.com/dwgexporter.php
I am not aware of any API for driving this, nor would I assume that one currently exists.
However, I am checking with the development team for you to make sure.
Best regards,

Re: C++ : can we do everything?
Dear Arnaud,
The Revit API is based on .NET.
You can use any language support .NET to interact with it.
There are no differences in functionality between different .NET languages.
A lot of the items in your list have nothing to do with Revit.
It seems you come from the AutoCAD side of programming.
That may make it harder for you to learn (and accept) how to work in the BIM world.
Revit and its API is different:
