Description

The Arch Site is a special object that combines properties of a standard FreeCAD group object and Arch objects. It is particularly suited for representing a whole project site, or terrain. In IFC-based architectural work, it is mostly used to organize your model, by containing building objects. The site is also used to manage and display a physical terrain, and can compute volumes of earth to be added or removed.

Usage

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

Typical workflow

Start by creating an object that represents your terrain. 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 ДаніTerrain 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 and wind diagrams

If Ladybug is installed on your system, Arch Sites can display a sun path diagram and/or a wind rose. For this, ДаніLongitude, ДаніLatitude and ДаніDeclination (previously ДаніNorth Deviation) must be correctly set, and ВиглядSolar Diagram or ВиглядWind Rose set to true.

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

See also: Arch API and FreeCAD Scripting Basics.

The Site tool can be used in macros and from the Python console by using the following function: 

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

Example: 

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

A sun path diagram can be created with the following function, independently of any site. 

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)
