GeometryObject.Name via Revit API

[AAlKallas]

Hi All,

I hope you are doing well.

Could someone please help me to get the name of a GeometryObject using the Revit API in C#?

Specifically, I am trying to achieve the same name as displayed in AutoCAD when the Revit file is exported as DWG.

For your reference, I have attached both the Revit and AutoCAD files.

Thank you in advance for your support!

Hi @AAlKallas 

 Are you trying to create Revit Object using AutoCAD file ? I didn't understand your context

[AAlKallas]

No!
I need help retrieving the name of a GeometryObject for a DirectShape created from a STEP file using the Revit API in C#.

This name is visible in AutoCAD when the DirectShape is exported to DWG, but I want to access it directly from the Revit API without having to export it to DWG.

You need directly access the DWG file using Revit API? Still I have confusion 

[AAlKallas]

If you open the Revit file I shared earlier, you will see a DirectShape without a name.

However, the name I am looking for is embedded in the GeometryObject, as demonstrated when exporting the file to DWG (shared previously).

My goal is to get this specific name directly from the Revit API using C# and rename the DirectShape accordingly, without having to rely on a DWG export.

Hi @AAlKallas 

I got your question, it is a DirectShapeType name, so you need to access the DirectShapeType to get the name. Kindly check the below code for additional reference.

And thank you for you replies 🙂

Reference Code Snippet

///Selection Reference
Reference selRef = uiDoc.Selection.PickObject(ObjectType.Element, "Select elements");

///Get Element
Element e = doc.GetElement(selRef);

///Get Symbol Id
Options options = new Options { ComputeReferences = true };

GeometryElement geometryElement = e.get_Geometry(options);

foreach (GeometryObject geoInst in geometryElement)
{
    if (geoInst is GeometryInstance)
    {
        GeometryInstance geoInstance = geoInst as GeometryInstance;

        SymbolGeometryId symbolId = geoInstance.GetSymbolGeometryId();
        Element symElement = doc.GetElement(symbolId.SymbolId);

        if (symElement is DirectShapeType)
        {
            TaskDialog.Show("Symbol Id", symElement.Name);
        }
    }
}

 Output

Hope this will helps 🙂
