Rotate family instance

[devX6MRR]

Hi, 

I'd like to know if there is a way to rotate a just-inserted family instance as shown in the video below.

The video is from AutoCad

are you sure that this is a right kind of forum for this post? It is forum for application programming interface.

I'm sure it's the right place 

I'm inserting family with the "PromptForFamilyInstancePlacement" and i'dlike to launch the command to rotate the programmatically.

In the video i attached rotation follows immediately the insertion because the program provide to it.

I hope being more clear now.

public void RotateColumn(Autodesk.Revit.DB.Document document, Autodesk.Revit.DB.Element element)
{
    XYZ point1 = new XYZ(10, 20, 0);
    XYZ point2 = new XYZ(10, 20, 30);
    // The axis should be a bound line.
    Line axis = Line.CreateBound(point1, point2);
    ElementTransformUtils.RotateElement(document, element.Id, axis, Math.PI / 3.0);
}

from the RevitAPI.CHM

Thanks, Ibrahim Naeem

Here Goes:

LocationPoint lp = familiyinstance.Location as LocationPoint;
 XYZ ppt = new XYZ(lp.Point.X, lp.Point.Y, 0);
Line axis = Line.CreateBound(ppt, new XYZ(ppt.X, ppt.Y, ppt.Z + 10));

using (Transaction t = new Transaction(Command.doc, "Rotate"))
{

t.Start();
 ElementTransformUtils.RotateElement(Command.doc,familiyinstance.Id, axis, (Math.PI / 180) * (angle);
 t.Commit();

}

Thanks & Regards

I'm sorry but i had a problem with another project and I could check solutions only this morning.

The solution best fit my problem is the @Anonymous's one.

I'd like to ask another thing: how can i get the variable angle the i saw in the snippet?

Thank you again
