How to detect the orientation of pipe fittings connected to the pipe?

[Anonymous]

Hi as shown in the above graphics, i have to find the orientation of the pipe fittings and the distance between the start point.

Can anyone suggest me how to do this using revit API?

Thank you in advance.

At this blog post (http://adndevblog.typepad.com/aec/2014/12/revitapi-align-2-pipes-through-center-lines.html), you'll find the following code that might help

private static Line GetCenterline(Pipe pipe)
{
Options options = new Options();
options.ComputeReferences = true; //!!!
options.IncludeNonVisibleObjects = true; //!!!
if (pipe.Document.ActiveView != null)
options.View = pipe.Document.ActiveView;
else
options.DetailLevel = ViewDetailLevel.Fine;

var geoElem = pipe.get_Geometry(options);
foreach (var item in geoElem)
{
Line lineObj = item as Line;
if (lineObj != null)
{
return lineObj;
}
}
return null;
}
