helical stair

Advance PowerPack 2016 for Autodesk[R] Advance Steel 2016 adds a wealth of localized manufacturer profiles and default settings, as well as new tools for creating splines of complex

helical stair

stringers, tools for automatic creation of floor coverings to standard grating sizes, improvements to many of the existing tools with new functionality and strategically, the introduction of a bi-directional link with Autodesk[R] Advance Steel and Advance Workshop that allows users to retrieve and graphically display production data in real-time, which can be published to the cloud for access in the field.

Simplistically, a

Again, however, specifics of place have prevailed as the cruciform arrangement has been usefully colonised by exhibition designers Thomas Matthews and linked by A & M's dramatic

helical stair

, situated at the crossing point where the Thompson Equatorial telescope originally stood.

Larson wondered at the difficulty of installing the

helical stair

. Ironically, installing the stair was straightforward.

Instead of using his original plan for a wall of glass, the architect settled on a half-wall of windows, which draws a visitor's attention away from the window and focuses it on the

helical stair

. The window plan also diminishes the A motif.

A gym, sauna, hydrotherapy bath and music room are located in adjacent modules, while an upper deck, reached via a

helical stair

rising through an atrium, has a tv lounge, library and office.

The two parts are linked by a

helical stair

that sweeps down in a supple curve from the new entrance hall that anchors the north edge of the exhibition space.

Spiralling up from the main hall, a

helical stair

leads to the various reading room levels.
