Arch Site/fr

Description
L'objet Arch Site est un objet spécial qui combine les propriétés d'un objet groupe FreeCAD standard et un objet Arch. Il est particulièrement adapté pour représenter un site entier, ou un terrain. Dans le travail d'architecture SFI, il est surtout utilisé pour organiser votre modèle, qui contient un objet building. Arch Site est également utilisé pour gérer et afficher un terrain physique, et peut calculer le volume de terre a ajouter ou supprimé.

Utilisation

 * 1) Optionnellement, selectionnez un ou plusieurs objets pour les inclure dans votre nouveau site
 * 2) Pressez le bouton , ou les touches  et

Options

 * After creating a site, you can add more objects to it by drag and dropping them in the Tree View or by using the [[Image:Arch Add.png|16px]] Arch Add tool. This only determines which object is part of the given site, and has no effect on the terrain itself.
 * You can remove objects from a site by drag and dropping them out of it the Tree View or by using the [[Image:Arch Remove.png|16px]] Arch Remove tool
 * You can add a terrain object by editing the Site's Terrain property. The terrain must be an open shell or surface.
 * You can add volumes to be added or subtracted from the base terrain, by double-clicking the Site, and adding objects to its Subtractions or Additions groups. The objects must be solids.
 * The Extrusion Vector property can be used to solve some problems that can appear when working with subtractions and additions. In order to perform those additions/subtractions, the terrain surface is extruded into a solid, which is then appropriately unioned/subtracted. Depending on the terrain topology, this extrusion might fail with the default extrusion vector. You might therefore be able to remedy the problem by changing this to a different value.

Properties

 * : The base terrain of this site
 * : The street and housenumber of this site
 * : The postal or zip code of this site
 * : The city of this site
 * : The country of this site
 * : The latitude of this site
 * : The longitude of this site
 * : An url that shows this site in a mapping website
 * : The area of the projection of this object onto the XY plane
 * : The perimeter length of this terrain
 * : The volume of earth to be added to this terrain
 * : The volume of earth to be removed from this terrain
 * : An extrusion vector to use when performing boolean operations
 * : Remove splitters from the resulting shape

Typical workflow
Start by creating an object that represents your terrain. It must be an open surface, not a solid. For example, it is easy to import mesh data, that can be turned into a Part Shape from menu Part -> Create Shape from Mesh.... Then, create a Site object, and set its Terrain property to the Part we just created:



Create some volumes (they must be solids) that represent the areas that you wish to be excavated or filled. Double-click the Site object in the Tree View, and add these volumes to the Additions or Subtractions groups. Click OK.



The site geometry will be recomputed and the areas, perimeter, and volumes properties recalculated.



Script
L'outil site est utilisable dans une macro et dans la console python en utilisant la fonction suivante :

crée un site en incluant les objets dans la liste.
