This class is used to store externally created geometric shapes. Primary intended use is for importing shapes from other data formats such as IFC or STEP. A DirectShape object may be assigned a category. That will affect how that object is displayed in Revit.

Namespace: Autodesk.Revit.DB
Assembly: RevitAPI (in RevitAPI.dll) Version: 21.0.0.0 (21.1.1.109)
Since:  2015

Syntax

C#
public class DirectShape : Element
Visual Basic
Public Class DirectShape _
	Inherits Element
Visual C++
public ref class DirectShape : public Element

Remarks

DirectShape is not a replacement for "real" Wall, Roof, Window, etc. It would typically be used where there is not enough information to create, e.g., a Wall, or full functionality of a Wall object is not needed. Some category-specific functionality may be available. If you need to modify a shape held by a DirectShape object, use Revit Geometry API, and then store the modified shape back to the DirectShape object.

Examples

CopyC#
// Create a DirectShape Sphere
public void CreateSphereDirectShape(Document doc)
{
    List<Curve> profile = new List<Curve>();

    // first create sphere with 2' radius
    XYZ center = XYZ.Zero;
    double radius = 2.0;    
    XYZ profile00 = center;
    XYZ profilePlus = center + new XYZ(0, radius, 0);
    XYZ profileMinus = center - new XYZ(0, radius, 0);

    profile.Add(Line.CreateBound(profilePlus, profileMinus));
    profile.Add(Arc.Create(profileMinus, profilePlus, center + new XYZ(radius, 0, 0)));

    CurveLoop curveLoop = CurveLoop.Create(profile);
    SolidOptions options = new SolidOptions(ElementId.InvalidElementId, ElementId.InvalidElementId);

    Frame frame = new Frame(center, XYZ.BasisX, -XYZ.BasisZ, XYZ.BasisY);
    if (Frame.CanDefineRevitGeometry(frame) == true)
    {
        Solid sphere = GeometryCreationUtilities.CreateRevolvedGeometry(frame, new CurveLoop[] { curveLoop }, 0, 2 * Math.PI, options);
        using (Transaction t = new Transaction(doc, "Create sphere direct shape"))
        {
            t.Start();
            // create direct shape and assign the sphere shape

            ds.SetShape(new GeometryObject[] { sphere });
            t.Commit();
        }
