3D modelling helps new V&A Dundee to take shape
Advances in technology have enabled the new V&A design museum to take shape on Dundee's waterfront.
The building's curves mean none of its walls are completely flat.
A 3D model controls every aspect of the project, helping engineers envisage how the structure will twist and turn while supporting itself.
BBC Scotland's science correspondent Kenneth Macdonald has been taking a closer look at how it works.
