############# 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

sudo make install

this should build a binary file 'brep_to_xml' in /bin, which is 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.
