When I open an airfoil component file, I have an error message !
Please check your directories :
I suppose you have installed TraCFoil in the directory "C:\Program Files\TraCFoil".
- Make a subdirectory for your airfoils files, you name it "airfoils" for example and a subdirectory for your Set of ribs, you name it "profils evolutifs" for example.
- You must copy the airfoils files in the subdirectory "C:\Program Files\TraCFoil\airfoils".
Run TraCFoil, go to the View menu and,
- Select in Template defaults Select Coordinates Path (in red), use the Browse button to select the subdirectory "C:\Program Files\TraCFoil\airfoils",
- Select Coordinates Path Set of ribs, use the Browse button to select the subdirectory ""C:\Program Files\TraCFoil\profils evolutifs",
- Click on Save button.
See the coordinates of your airfoil, something is wrong.

When I open an airfoil generate by "set of ribs"I have an error message!
see above

How Generate full set of ribs ?
Use the Menu "Generate full set of ribs"
You must enter :
- the number of intermediate ribs,
- the airfoil and major chord length,
- the airfoil and minor chord length.
- Click on Compute or press "Enter" for saving airfoils on the disk on the subdirectory "C:\Program Files\tracfoilE\setofribs"
Now open the Airfoil xxxxxR1.dat, use the percent position for you spars and holes, and save your configuration with the "Save as Airfoil components".
Open the Airfoil xxxxxR2.dat, and so on.....

I have an error message xxx, like that "the component is not registered ..." .
Error message at launch: Missing file MSVBVM50.DLL :
Error message at launch: The language DLL.dll or 409 could not be found
- repeat the complete installation from ctracfoilE.exe.
Other cases: Contact me by indicating the exact error message.

Do not confuse an airfoil file, a file rib component, a rib and a DXF file ?
- airfoil file:
TraCFoil use *.dat Selig's x,y format or *.cor (coordinate file)
The format is :
The first line describes the airfoil.
1.000000 0.xxxxxx Trailing Edge - Start
0.9xxxxx 0.xxxxxx along Upper surface towards Leading Edge
......... .........
0.xxxxxx 0.xxxxxx Leading Edge
......... .........
0.xxxxxx -0.xxxxxx along Lower surface back towards Trailing Edge
0.900000 -0.xxxxxx
1.000000 0.xxxxxx Trailing Edge - End
Open only by menu File /Open Airfoil file or the Airfoils button.
Create new Coordinates by menu Utilities/Create new coordinates file

- Rib components:
File *.tra (TraCFoil) = a file of the components of your rib (the airfoil file, the chord, the sheeting thickness, the leading edge width, the spars, the holes, the trailing edge width, the station lines, foam, washout angle... )
Open only by menu File /Open Rib components
to save and name the active Rib with all the components menu File /Save as Rib components

- a rib :
is displayed (from an airfoil), may have components (Chord, thickness, leading edge, trailing edge, spars, holes ..)
see menu Rib

- DXF files :
files *.DXF (Drawing eXchange Format) = is a CAD data file format developed by Autodesk[1] for enabling data interoperability between AutoCAD and other programs. See Wikipédia information
TraCFoil can NOT open that files
Can be exported from TraCFoil only via menu File/Export to DXF

Exploiting DXF
TraCFoil uses the DXF Reference Autodesk DXF (AutoCAD ® Release 14 database and AutoCAD ® 2000) normally compatible with all versions
See "résultats de l'enquête sur le DXF" in french(PDF)
For information DraftSight Béta is free an use DXF and dwg format.
An example : DraftSight (CAO) sur Debian 8

DXF file is not correct when I open it in a CAD drawing program.
The decimal symbol must be the point (dot). Check Control Panel / Regional Settings / Number. See how to (in french).

When I try to open an airfoil, I get this error message: Coordinate are the same on line X=0and line x=0
So edit the airfoil file by Utilities/Create new coordinates file or a notepad, check that the coordinates at the line X=0 which should be twice, if yes delete on row.
Warning: check that the decimal symbol must be the point (dot). Check Control Panel / Regional Settings / Number. See how to (in french).

I sent an email and I have no answer? what are the possible reasons ?
- You use IncrediMail and all messages sent go to the trash!
- You've sent a mail with an attachment over 2MB and therefore the mail is in the trash, if you want to send files using an appropriate system!
