Hello, Jeremy.

In Revit 2013 API added new class - DataStorage - an element which provide storage for entities with any data for whole project. But there are no examples to demonstrate how does it work and how to use it properly.

I think it would be perfect if you explain it.

Best regards, Victor.

Hi Jeremy..

I am trying to create NewFamilyInstance using NewFamilyInstance Method (Reference, Line, FamilySymbol) constructor. sample code...

LocationCurve wallCurve = wall.Location as LocationCurve;
XYZ startPt = wallCurve.Curve.get_EndPoint(0);
XYZ endPt = wallCurve.Curve.get_EndPoint(1);
XYZ dir = endPt - startPt;
XYZ cutVec = dir.CrossProduct(XYZ.BasisZ);

ReferencePlane rp = doc.Create.NewReferencePlane(startPt, endPt, cutVec, doc.ActiveView);

famIns = doc.Create.NewFamilyInstance(rp.Reference, Line.get_Bound(startPt, endPt), familySymbol);

Revit shows error "Family cannot be placed on this line as it does not coincide with the input face."

But in Revit 2012, it works fine.
Is there any change in NewRefPlane() or NewFamilyInst() internally in revit 2013?
If any please share any sample..

Thanks..

Hi Jeremy,

First thank you for this wonderful blog.

With the 2012 API I used PipeSizeSettings listPipeSizeSettings = PipeSizeSettings.GetPipeSizeSettings(document) to get the list of PipeSize, but I can not find PipeSizeSettings in 2013 API.

Have you an idea how to do that?

Thank you

I am having problems with Revit MEP 2013, I can not edit any fire pipes and when ever I try the program just hangs and evntually I have to restart. When I was using Revit MEP 2012 this never happened.

Dear Jeremy,

I played a little bit with the PreviewControl in a modal Dialog. I changed the orientation of a perspective View3d with a user input (a trackbar) in that PreviewControl but I have problems to redraw the PreviewControl! The changes are only visible after clicking with the mouse on the control and scrolling with the mouse wheel! Is their a possible to redraw the PrieviewControl automatically?

I was looking for a list of pipe sizes in a project and thought I would let you know what I used:

private void GetPipeSegmentSizesFromDocument(Document document)
{
FilteredElementCollector collectorPipeType = new FilteredElementCollector(document);
collectorPipeType.OfClass(typeof(Segment));

IEnumerable segments = collectorPipeType.ToElements().Cast();
foreach (Segment segment in segments)
{
StringBuilder strPipeInfo = new StringBuilder();

using (System.IO.StreamWriter file = new System.IO.StreamWriter(@"C:\REVIT\WriteLines.txt", true))
{
file.WriteLine(Convert.ToString(segment.Name));

}
foreach (MEPSize size in segment.GetSizes())
{
using (System.IO.StreamWriter file = new System.IO.StreamWriter(@"C:\REVIT\WriteLines.txt", true))
{
file.WriteLine(Convert.ToString(Math.Round(size.NominalDiameter * 25.4 * 12, 0)) + " " + Convert.ToString(Math.Round(size.InnerDiameter * 25.4 * 12, 0)) + " " + Convert.ToString(Math.Round(size.OuterDiameter * 25.4 * 12, 0)));

}
}
}
}
