Hi every one:
any one can give me some hint about how to run the MS FS models under
flightgear?
I have searched for long time, It is said Wolfram's manual can help,
http://home.t-online.de/home/Wolfram.Kuss/,this websit looks
and also is Germany
I don't understand.
I very appreciate your help.

Yes I can help in detail,
Hello Clifford
You will find as attached document the very beginning of
How to :for conversion (importing) from MSFS to Flightgear
i don't know if that first draft will help you.
You will discover, a such manipulation is rather difficult.
Tell us what is missing for you

That document is only an quick help, it should be improved
The purpose of FlightGear is to offer a realistic flight simulator which gives
to anybody, opportunity and facilities to manipulate every aircraft
characteristics parameters.
One could prefer to spend the best of is time to that technical aspect, to test
these parameters with a nice 3D model,rather than loosing is time to make model.
Only, for a home usage, converting a .mdl Aircraft is an opportunity. He can
get quickly, a model which is yet existing ( most of these models are
protected by copyriht)
You are supposed to know:
how to place a 3D model in the FlightGear world
how to use the FG properties and animate a 3D model
how to build a flight dynamic model with Yasim or JSBSim or Uiuc or
Larcsim .
AOverview.
The processing of an Aircraft.mdl format depend on the PLIB library
functionality.
PLIB being used by FlightGear.
That library contains the input function, which gives the possibility to
extract from a .mdl format the full vertex and faces definitions of a
model. The texture coordinates are kept.
That library contains the output functions, for translation in others 3D
formats, the mains format are: .ac, .dxf,.3ds and others
(the full list can be seen in the PLIB source--plib/src/ssg/...).
The mdl animations are not converted .
This help-description is Plib 1.8.4 related to.
It has been experimented under Linux, only, we cannot guaranty his full
availability under others operating system (however it should do, because of
the portability of FlightGear, and Plib)
We will see in the next chapters:
-limitations of these resources and how to use directly a .mdl
model in FlightGear, without any external translation.
-how to convert a mdl model
B=Limitations and how to use directly a mdl model.
One same extension name define in fact several .mdl format,
They are not compatible, they are on the MS FS side dedicated to, FS98 or
FS2000 or FS2002 or FS2004 and MS Player has to try to convert the old models
to get it running on newer Flying simulator game.
The static part of the Aircraft.mdl is supposed to be existing in a .bgl
format, encapsulated in the.mdl format
PLIB looks for the .static bgl part--beginning address and length.
It try to extract that part only.
FS98
By that way, because mdl FS98 format is simple, due to FS98 limitations itself.
PLIB is able to extract it at the good scale, the good orientation, the good
textures (textures are in a specific format which is red by PLIB)
In FG it is necessary to include the mdl model and the textures in the same
directory
(usually -- ..yourAircraft/Models/..) and to declare it in the file
yourAircraft-set.xml.
however a limitation is existing: you do not get any animation.
An other limitation coming from FS98, the model is not detailed, rather simple,
not up to the quality we are waiting for the last FlightGear release
FS2000 to 2004
Here we depend mainly on the CAD 3D program which was used to build the
original model.
(in order to help for a quick test of usability, you could use threedconvert,
it will be explained in the next chapter- How to convert)
Models originally modelled with Abacus FSDS modeller gives the best result
That type of mdl models can be directly used.
That kind of model have a very good quality, detailed, up to the FlightGear
quality, the good scale, the good orientation, the good texture.(textures ares
in bmp format)
The process is identical to FS98 model:
In FG it is necessary to include the mdl model and the textures in the same
directory
(usually -- ..your Aircraft/Models/..) and to declare it in the file your
Aircraft-set.xml.
For the Linux user it could happen a difficulty with the texture name (wrong
upper case, lower-case), which must be adapted to the model request (error
messages during FlightGear loading)
However a limitation is existing: you do not get any animation.
Here an example of a model which can
