The Transform of BoundingBoxXYZ is useless.

[Anonymous]

I found that I could not control the 'Transform' properties to modify the BoundingBox.

```csharp

var box = new BoundingBoxXYZ();
var builder = new StringBuilder();

builder.AppendLine("Before Rotation Matrix:");
builder.AppendLine($"The Min of Box: {box.Min}");
builder.AppendLine($"The Max of Box: {box.Max}");
builder.AppendLine($"The Transform of Box: {box.Transform}");

// It doesn't seem to work.
box.Transform = Transform.CreateTranslation(XYZ.BasisZ * 200);

builder.AppendLine("After Rotation Matrix:");
builder.AppendLine($"The Min of Box: {box.Min}");
builder.AppendLine($"The Max of Box: {box.Max}");
builder.AppendLine($"The Transform of Box: {box.Transform}");

```

Oh dear. You sound a bit negative here. I guess it depends on how it is used. I think that certain aspects of setting the view crop box, scope box and section box make use of this functionality. You can probably set the bounding box transform, just as you have done, and then make use of it in your own code, which you are apparently not yet doing. I guess Revit does, in certain situations. For instance, take a look at the documentation and sample code of the Transform property:

Yes, I should have thought of that, didn't look in the right place.
