############# Initialization ###################################################

so far it only works on a linux box with libopencascade-dev 6.5-0 installed.

in order to build the brep_to_xml converter, go to FreeCAD/BrepConversion and

run:

make

make install

or

sudo make install

this should build a binary file 'brep_to_xml' and copy it to ~/bin if

you call make install as current user or to /bin if you call it with

sudo. Make sure that in any case the corresponding bin directory is in

your PATH environment variable. This binary is then called by Brep.hs

while running in case it reads an xml containing at least one of the

following:

rectangle

line

it is possible to skip this step, but then the program would crash, giving a

runtime error if it needs to read the details of an object from a .brp file.

############ Using the module #################################################

Compile Hets if it is not already done.

cd /path/to/Hets

make

To open the free-cad file in hets and visualize the graph, run:

./hets -i fcstd path/to/freecad/file.fcstd -g

To export the free-cad file xontent into an xml, run:

./hets -i fcstd -o fcxml path/to/freecad/file.fcstd

############# Visualising the xml outputted by Hets ############################

In order to generate the free-cad document from the xml file

generated by

./hets -i fcstd -o fcxml path/to/freecad/file.fcstd

you need free-cad-0.11 or newer.

--Go into the directory containing 'fcmacro.py', which is in

'Hets/FreeCAD/Plugins' by default;

--Open freecad from the terminal from that directory;

--Open the python interpreter within freecad if it is not already opened by

default.

--In the freecad python interpreter execute the following commands:

import fcmacro

fcmacro.fromHets('path/to/file.xml', App, Gui)

--The content should be generated automaticly and the view centered on the

collection of objects.

The output in the python interpreter should be the information from the xml.
