Setting up Survey Point programtically

[Anonymous]

Hello Everyone,

I want to perform a seemingly trivial task. I am trying to setting-up positional values (NS EW Elev) of a Survey point, programtically.

One of the articles on this topic says its not possible via API. However the article is almost three years now, so i hope API has got richer in this area.

if(basePoint.IsShared)
{
                  basePoint.Pinned = false;
                  basePoint.get_Parameter(BuiltInParameter.BASEPOINT_NORTHSOUTH_PARAM).Set(100);
}

This code throws exception: "There parameter is read-only".

Is there a better / another way of doing it in Revit API 2016?

Thanks in advance.

Best regards,

Kinjal.

Finally figured-it-out. It can be achieved uidoc.Document.ActiveProjectLocation.

Following is code to set value of Survey point programtically (that is values for NS, EW, Elev):

//1: Set Survey point values

ProjectLocation projectLocation = uidoc.Document.ActiveProjectLocation;

ProjectPosition projectPosition = projectLocation.get_ProjectPosition(origin);

projectPosition.NorthSouth = <double value>;
projectPosition.EastWest = <double value>;
projectPosition.Elevation = <double value>;;
projectLocation.set_ProjectPosition(origin, projectPosition);

//2: Move survey point wrt Project base coordinate
var locations = collector.OfClass(typeof(BasePoint)).ToElements();

foreach (var locationPoint in locations)
{
        BasePoint basePoint = locationPoint as BasePoint;
        if (basePoint.IsShared)
        {
                basePoint.Pinned = false;
                basePoint.Location.Move(new XYZ(0, 1, 0));
        }
}

One issue remains. If survey point is relocated (see step 2 in code above) to Origin instead of a non-origin (0,1,0 in this case), the Survey point doesn't move to origin and appears at negative relational position from Project Base point. But thats separate issue so i will make it to a separate question. Thanks everyone.
