DBGT10K_22_v04 - 02 Coverage Element
Description
It describes one of the various roofing parts of a building, i.e. pitches, terraces, domes, etc. but also elements to complete the roofing and which are mutually exclusive with respect to the pitches in the view from above, i.e. ''the roofing pitches''. While the elements at the top but superimposed on the roofs (ie that do not puncture the aquifer as the case of chimneys) are described among the architectural details. See: Acquisition of two of the four roof layers of the Cassone Edilizio Among the objects that participate in the three-dimensional modeling there are the roofs of the building. These are cut at most on each building such that each roof consists of one or more aquifers, and each aquifer as a separate surface with a closed 3D broken outline; the vertices of the break have the value q of the share that belongs to them. With reference to the proposed three-dimensional model, the reference surface is that consisting of each aquifer of the roof to which is associated as an extrusion quota that of the point of the aquifer having a minimum quota; in this case this share is still the eaves share of the building. The geometric planimetric and altimetric congruence between the aquifers and the built bodies that they cover must be verified. The extrusion surfaces of the roofing elements can also be the roofs of the attic floors, terraces, well terraces inserted in the slopes of the roofs, those located on towers, etc. For all these types of extrusion surfaces the relative extrusion share will be the eave share of the building on which they insist. Also included are the flat or inclined aquifers of hemispherical domes or similar to them that will be made by dividing them into contour segments (closed polyline 3D). Each segment will constitute the extrusion surface and its extrusion share will be the share of the dome base. See: Here are some examples of roofing elements corresponding to aquifer surfaces. See: And the result of the extrusion up to the height in the eaves provides in fact the volume of the attics.
