ReferenceIntersector return distance

[Anonymous]

I'm experimenting with ReferenceIntersector and I don't understand the problem i'm having with distance. I'm filtering for columns and If I use 'referenceIntersector.Find' it returns a list of columns intersecting along the direction. But if I use 'referenceIntersector.FindNearest' I can only get a column if it's less than 1'-6" away. What am I missing or what should I be looking for? My start and direction XYZ are both (0,0,0).

            ElementFilter columnFilter = new ElementCategoryFilter(BuiltInCategory.OST_StructuralColumns);
            ReferenceIntersector referenceIntersector = new ReferenceIntersector(columnFilter, FindReferenceTarget.Element, view3D);
            ReferenceWithContext referenceWithContext = referenceIntersector.FindNearest(_rayStart, _rayDirection);

Dear Bthatcher,

Thank you for your query.

Maybe your 3D view is set up to eliminate all geometry outside certain bounds?

Here are two discussions on using FindNearest by The Building Coder:

The Building Coder samples also includes sample code for that:

I hope this helps.

Best regards,
