IfcOpenShell

============

open source (LGPL) software library for working with the IFC file format

http://IfcOpenShell.org

Compiling on Windows

====================

Users are advised to use the Visual Studio .sln file in the win/ folder.

For Windows users a prebuilt Open CASCADE version is available from the

http://opencascade.org website. Download and install this version and

provide the paths to the Open CASCADE header and library files to MS

Visual Studio C++.

For building the Autodesk 3ds Max plugin, the 3ds Max SDK needs to be

installed as well as 3ds Max itself. Please provide the include and

library paths to Visual Studio.

For building the IfcPython wrapper, SWIG needs to be installed. Please

download the latest swigwin version from http://www.swig.org/download.html.

After extracting the .zip file, please add the extracted folder to the PATH

environment variable. Python needs to be installed, please provide the

include and library paths to Visual Studio.

Compiling on *nix

====================

Users are advised to build IfcOpenShell using the cmake file provided in

the cmake/ folder. There might be an Open CASCADE package in your operating

system's software repository. If not, you will need to compile Open

CASCADE yourself. See http://opencascade.org.

For building the IfcPython wrapper, SWIG and Python development are

required.

To build IfcOpenShell please take the following steps:

$ cd /path/to/IfcOpenShell/cmake

$ mkdir build

$ cd build

Optionally:

$ OCC_INCLUDE_PATH="/path/to/OpenCASCADE/include"

$ OCC_LIBRARY_PATH="/path/to/OpenCASCADE/lib"

$ export OCC_INCLUDE_PATH

$ export OCC_LIBRARY_PATH

$ cmake ../

$ make

If all worked out correctly you can now use IfcOpenShell. For example:

$ wget ftp://ftp.dds.no/pub/ifc/Munkerud/Munkerud_hus6_BE.zip

$ unzip Munkerud_hus6_BE.zip

$ ./IfcObj Munkerud_hus6_BE.ifc

$ less Munkerud_hus6_BE.obj

Or:

$ wget ftp://ftp.dds.no/pub/ifc/Munkerud/Munkerud_hus6_BE.zip

$ unzip Munkerud_hus6_BE.zip

$ python

>>> import IfcImport

>>> IfcImport.Init('Munkerud_hus6_BE.ifc')

>>> geom = IfcImport.Get()

>>> geom.name

>>> for v in geom.mesh.verts: v
