Microstation C# Update 16 : Set Scale and Active Angle

We want to scale an element and set its active angle.

We are applying the below chunk of code for scale of element. Is this the appropriate way to do it?

// where center is origin of the element and scale value as 0.25, 0.50, 0.75
DTransform3d transform = DTransform3d.FromUniformScaleAndFixedPoint(center, scale);
TransformInfo transformationInfo = new TransformInfo(transform);
newelement.ApplyTransform(transformationInfo);

How to set the active angle for an element and rotate it by that active angle?
