Descriere

Site-ul Arch este un obiect special care combină proprietățile unui obiect standard al grupului FreeCAD și a obiectelor Arch. Este deosebit de potrivit pentru a reprezenta un întreg sit de proiect sau teren. În cazul lucrărilor arhitecturale bazate pe IFC, se utilizează cea mai mare parte pentru a vă organiza modelul, conținând obiecte building. Site-ul este, de asemenea, folosit pentru a gestiona și a afișa un teren fizic și poate calcula volumul de pământ care trebuie adăugat sau eliminat.

Cum se folosește

  1. Optionally, select one or more objects to be included in your new site
  2. Press the Arch Site button, or press the S then I keys

Opţiuni

  • After creating a site, you can add more objects to it by drag and dropping them in the Tree View or by using the 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 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.

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.

Solar diagram

If pysolar is installed on your system, Arch Sites can display a solar diagram. For this, Longitude, Latitude and NorthDeviation properties must be correctly set, and SolarDiagram view property turned on. introduced in 0.17

Note: If you don't have Ladybug, pysolar (version 0.7 and above) is still supported to generate sun path diagrams, but not wind roses. However, Ladybug is a much more powerful tool that will probably be used more in the future, so we recommend using it instead of pysolar. Ladybug can be installed simply via the pip Python package manager.

Scripting

Scrip-Programare

Instrumentul Site poate fi utilizat în macros și de la consola python utilizând următoarele funcții: 

Site = makeSite(objectslist=None, baseobj=None, name="Site")

creează un site incluzând obiectele din lista dată.

Exempluː 

import FreeCAD, Draft, Arch

p1 = FreeCAD.Vector(0, 0, 0)
p2 = FreeCAD.Vector(2000, 0, 0)
baseline = Draft.makeLine(p1, p2)
Wall = Arch.makeWall(baseline, length=None, width=150, height=2000)
FreeCAD.ActiveDocument.recompute()

Building = Arch.makeBuilding([Wall])
Site = Arch.makeSite([Building])

FreeCAD.ActiveDocument.recompute()
FreeCAD.Gui.ActiveDocument.ActiveView.viewIsometric()

Solar diagram

As long as the pysolar module is present, a sun path diagram can be added to the site. Set the longitude, latitude and declination angles as appropriate, as well as an adequate scale for the size of your model.

At this time, the diagram serves only informative purposes and is there for visual display. For a sun path diagram that enables visualizing shadows and interactively changing dates and times, the best option is to use an external website that allows uploading 3D models. Some of them support .obj and .stl formats for instance, which can be exported to with FreeCAD.

Please note that Pysolar 0.7 or above is required, and this version only works with Python 3. 

Site.Longitude = -46.38
Site.Latitude = -23.33
Site.Declination = 30
# Uncomment if you want to show the compass
# Site.ViewObject.Compass = True

Site.ViewObject.SolarDiagram = True
Site.ViewObject.SolarDiagramScale = 10000
FreeCAD.ActiveDocument.recompute()

Solar diagram independent of Site

O diagramă de însorire poate fi creată cu : 

Node = makeSolarDiagram(longitude, latitude, scale=1, complete=False)

import FreeCADGui, Arch

Node = Arch.makeSolarDiagram(-46.38, -23.33, scale=10000, complete=True)
FreeCAD.Gui.ActiveDocument.ActiveView.getSceneGraph().addChild(Node)
