Cornice BETTER

NOTE: some people have experienced troubleswith the above standalone .exe, especially on Windows XP. As I don't have anXP box, I can't tell what the problem is, but it has been reported that theissue might involve the wxPython version used (2.5.2.8). So I'm still providingthe exe of the previous version (0.5.2), built with wxPython 2.4, here. Maybe this helps...(if not, tellme... and if it does and you know why, tell me even more! ;-)NOTE 2 (For Windows and Mac advanced users): cornice comes with a custom directory tree view that needs to be compiled (being partially written in C) on Windows and MacOSX. The sources distribution comes with a precompiled module, but for python 2.3 only. So, if you are on python 2.4, you need to compile it yourself. It is actually not that hard, but at the moment undocumented. But if you have some experience with python, the distutils setup file to use is "dirctrl/dirctrl_mac/_dirctrlmac_helper_setup.py" (on OSX) or "dirctrl/dirctrl_win/_dirctrlhelper_setup.py" (on Win). DevelopmentDevelopment of Cornice has stopped. I will still accept patches for fixing bugs or updating translations, but I will not add new features. For those who are interested, the sources are available on BitBucket, using Mercurial. The repository is here: you have comments or questions, you can drop me an emailat .

A projecting cornice on a building has the function of throwing rainwater free of its walls. In residential building practice, this function is handled by projecting gable ends, roof eaves and gutters. However, house eaves may also be called "cornices" if they are finished with decorative moulding. In this sense, while most cornices are also eaves (overhanging the sides of the building), not all eaves are usually considered cornices. Eaves are primarily functional and not necessarily decorative, while cornices have a decorative aspect.

In Ancient Greek architecture and its successors using the classical orders in the tradition of classical architecture, the cornice is the topmost element of the entablature, which consists (from top to bottom) of the cornice, the frieze, and the architrave.[2]

Where a triangular pediment is above the entablature, the cornice continues all round the triangle, the two sides being "raking cornices". The vertical space below the cornice is typically decorated by dentils (little teeth), or the larger modillons. The soffit, or horizontal space under a projecting cornice, may be elaborately carved with vegetal designs.

A rake is an architectural term for an eave or cornice which runs along the gable of the roof of a modern residential structure. It may also be called a sloping cornice, a raking cornice. The trim and rafters at this edge are called rakes, rake board, rake fascia, verge-boards, barge-boards or verge- or barge-rafters.[3] It is a sloped timber on the outside facing edge of a roof running between the ridge and the eave.[4] On a typical house, any gable will have two rakes, one on each sloped side. The rakes are often supported by a series of lookouts (sometimes also called strong arms) and may be trimmed with a rake fascia board (which is not a true fascia) on the outside facing edge and a rake soffit along the bottom.

In an open cornice, the shape of the cornice is similar to that of a wide box cornice except that both the lookouts and the soffit are absent. It is a lower-cost treatment that requires fewer materials, and may even have no fascia board, but lacks the finished appearance of a box cornice.

Ancient Egyptian architectural tradition made special use of large cavetto mouldings as a cornice, with only a short fillet (plain vertical face) above, and a torus moulding (convex semi-circle) below. This cavetto cornice is sometimes also known as an "Egyptian cornice", "hollow and roll" or "gorge cornice", and has been suggested to be a reminiscence in stone architecture of the primitive use of bound bunches of reeds as supports for buildings, the weight of the roof bending their tops out.[6]

The term cornice may also be used to describe a form of hard window treatment along the top edge of a window. When used in this context, a cornice represents a board (usually wood) placed above the window to conceal the mechanism for opening and closing drapes. If covered in a layer of cloth and given padding, it is sometimes called a soft cornice rather than a hard cornice.

Cornices grow through the winter on the leeward side of wind exposed ridges and summits. Cornices range from small wind lips of soft snow to overhangs of hard snow larger than a school bus. They can break off the terrain suddenly and unexpectedly and can sometimes be triggered from a distance. Overhung cornices can pull back further than expected onto a flat ridge top and catch people by surprise. While large cornices are quite destructive by themselves, even a small cornice can be deadly if it carries you over a cliff or rocky terrain below. The impact from a Cornice Fall can also easily trigger slab avalanches on steep slopes below. Travel cautiously on corniced ridgelines, giving cornices or unknown edges a wide berth. Limit your exposure to slopes below cornices. Cornice Fall is most likely during periods of significant temperature warm-up or rapid cornice growth due to wind loading.

Cornice Fall is the release of an overhanging mass of snow that forms as the wind moves snow over a sharp terrain feature, such as a ridge, and deposits snow on the downwind (leeward) side. Cornices range in size from small wind lips of soft snow to large overhangs of hard snow that are 30 feet (10 meters) or taller. They can break off the terrain suddenly and pull back onto the ridge top and catch people by surprise even on the flat ground above the slope. Even small cornices can have enough mass to be destructive and deadly. Cornice Fall can entrain loose surface snow or trigger slab avalanches.

Cornices can never be trusted and avoiding them is necessary for safe backcountry travel. Stay well back from ridge line areas with cornices. They often overhang the ridge edge and can be triggered remotely. Avoid areas underneath cornices. Even a small Cornice Fall can trigger a larger avalanche and a large Cornice Fall can easily crush a human. Periods of significant temperature warm-up are times to be particularly aware of.

Cornices develop whenever snow is available for transport and the wind is sufficiently strong to move the snow. The ideal wind speed for cornice development is 15 to 25 mph. Stronger wind speeds tend to move snow further down the slope, which creates other hazards (see Wind Slab, Persistent Slab). Cornices can form quickly with favorable wind speeds and abundantly available snow, typically following a recent storm. Multiple wind events over time generate large overhanging cornices comprised of numerous hard snow layers often interspersed with soft weak snow layers or hollow tunnels.

Cornices develop in periods ranging anywhere from hours to all season. A brief wind event following storm snow quickly generates soft cornices on the lee of any terrain feature. Soft wind cornices are easy to trigger artificially. If they are not large, then they are often manageable by themselves. Soft Cornice Fall, however, can run long and fast while quickly entraining additional snow that results in a much larger and more dangerous avalanche. A longer wind event, typically lasting at least a day, generates larger and harder Cornices. These stiff Cornices may appear supportive of a human, but they cannot be trusted. Additional weight, from more snow load or a human, can result in a crack that easily propagates resulting in a Cornice Fall. This can happen from a distance resulting in a remote release. Cornices can build to very large sizes through the winter. These large Cornice Falls are difficult to trigger, but if they do, the consequences can be deadly.

Fortunately, Cornices are easy to see. Weather and terrain awareness are the best tools for recognizing potential cornice problems. When planning a backcountry trip, use topographic maps to learn where potentially hazardous cornices can form. Pay attention to weather observations during the past several days and wind forecasts to understand where Cornices are forming. While in the backcountry, look for cornice formation on the lee of terrain features. Look for local terrain-driven wind effects, which may generate Cornices in unexpected locations. Pay attention to unusual weather events. For example, winds from the east (often associated with a Front Range upslope storm) generate Cornices on westerly aspects. e24fc04721
