Hi @preeti.kumari9TBN6 ,

If you are looking for a way to access Level property of an element via Navisworks API, then I would suggest you use the search API.

Hey @Anonymous, Thank you for your response. Actually, I am not looking for the level property. My concern is how to get the elevation of a particular level. Basically, I wanted to create a bounding box from level to level(such as from level1 to level2) . This bounding box, I wanted to created a viewpoint accordingly. Hope, I make you understand my concern.

Hi @preeti.kumari9TBN6 ,

I created a simple Furniture elements in Revit.

I placed one furnitue in Level 0 and another one in Level 1 and exported the file to nwc.

I can see the level property category.From the property category, I can get the Elevation data property. Please see the attached images.

My Suggestion to you is
1)Get an element with category "Level" via search API
2)From "Level" property category, access the "elevation" data property and get it's value.

I think search API will help you to achieve what you want.

Here is the sample code

private void SimpleCode(Document doc) { string itemAndElevation = ""; Search search = new Search(); search.SearchConditions.Add(SearchCondition.HasCategoryByDisplayName("Level")); search.Selection.SelectAll(); ModelItemCollection collection = search.FindAll(doc, true); foreach(ModelItem item in collection) { DataProperty dataProperty=item.PropertyCategories.FindPropertyByDisplayName("Level", "Elevation"); string elevationValue = dataProperty.Value.ToString(); itemAndElevation = itemAndElevation + "\n" + item.DisplayName + " -- " + elevationValue; } MessageBox.Show(itemAndElevation); }

You can then access the "elevationValue" and create your bounding box.
