### Decal Property Type Change Example

Source: https://revapidocs.com/2024.htm

Illustrates the change in type for decal asset properties from AssetPropertyInteger to AssetPropertyInt64.

```C#
AssetPropertyInteger decalElementIdProp= (asset.FindByName("decalelementId") as AssetPropertyInteger);
if (decalElementIdProp.Type == AssetPropertyType.Integer)
```

```C#
AssetPropertyInt64 decalElementIdProp= (asset.FindByName("decalelementId") as AssetPropertyInt64);
if (decalElementIdProp.Type == AssetPropertyType.Longlong)
```

### Document.CreationGUID Property

Source: https://revapidocs.com/2024.htm

This snippet shows the new Document.CreationGUID property which represents the document's creation GUID from the document history.

```csharp
Document.CreationGUID
```

### Family Instance Creation API

Source: https://revapidocs.com/2024.htm

Shows the new location and usage of the NewFamilyInstance method in both family and project documents.

```C#
Autodesk.Revit.Creation.Document.NewFamilyInstance()
```

```C#
Autodesk.Revit.Creation.FamilyItemFactory.NewFamilyInstance()
```

### EvaluatedParameter.AsValueString Overload

Source: https://revapidocs.com/2024.htm

This snippet shows the new overload for EvaluatedParameter.AsValueString to format evaluated parameters with custom format options.

```csharp
EvaluatedParameter.AsValueString(Document, FormatOptions)
```

--------------------------------

### FilteredElementCollector Constructor

Source: https://revapidocs.com/2024.htm

Creates a FilteredElementCollector set to iterate the visible elements in a Revit link instance in a certain view of the host document. Elements returned by iteration of this collector will be from the Revit link instance's document.

```C#
FilteredElementCollector(Document hostDocument, ElementId viewId, ElementId linkId)
```

--------------------------------

### Filled Region Masking Region Creation

Source: https://revapidocs.com/2024.htm

Methods to create a masking region on a sketch plane in a 3D model family or a view specific masking region from given boundaries.

```C#
FilledRegion.CreateMaskingRegion(Document, SketchPlane, IList<CurveLoop>)
```

```C#
FilledRegion.CreateMaskingRegion(Document, ElementId, IList<CurveLoop>)
```

--------------------------------

### SunStudyTimeInterval Enum Values

Source: https://revapidocs.com/2024.htm

This snippet lists the new values for the Autodesk.Revit.DB.SunStudyTimeInterval enum, allowing for second-level precision in solar study time intervals.

```csharp
