it Works!! thank you for suggestion,
public static void ApplyNavisworksClipping(double cloudX, double cloudY, double cloudZ, double cloudXLen, double cloudYLen, double cloudZLen)
{
try
{
// Use culture-invariant formatting to ensure decimal points are always periods
System.Globalization.CultureInfo invariantCulture = System.Globalization.CultureInfo.InvariantCulture;
// Calculate the box corners
double minX = cloudX - cloudXLen / 2;
double minY = cloudY - cloudYLen / 2;
double minZ = cloudZ - cloudZLen / 2;
double maxX = cloudX + cloudXLen / 2;
double maxY = cloudY + cloudYLen / 2;
double maxZ = cloudZ + cloudZLen / 2;
// Create JSON string for OrientedBox3D format
string jsonClipPlaneSet = $@"
{{

// Remove newlines and extra spaces for a more compact JSON
jsonClipPlaneSet = jsonClipPlaneSet.Replace("\r", "").Replace("\n", "").Replace(" ", "");
// Log coordinates for debugging

bool success = Application.ActiveDocument.ActiveView.TrySetClippingPlanes(jsonClipPlaneSet);
if (!success)
{
System.Diagnostics.Debug.WriteLine("Failed to set clipping planes with TrySetClippingPlanes");
// Fall back to SetClippingPlanes which will throw an exception with more details if it fails
Application.ActiveDocument.ActiveView.SetClippingPlanes(jsonClipPlaneSet);
}
// Request a view update
Application.ActiveDocument.ActiveView.RequestDelayedRedraw(ViewRedrawRequests.All);
}
catch (Exception ex)
{
