Profile is a Windows 95 program intended to plot airfoils and templates. 
This is free software and is freely distributable under certain conditions; it comes with 
NO WARRANTY. See the GNU GPL included (GNU-GPL.txt) for details.

Full Source code is also available for those who wants to play with it or add new futures.
I want to keep responsible for incorporating all the changes into the official release,
of course, I will give you credit of the changes!!.
If some one wants to collaborate with a nicer manual  let me know!!

HISTORY
---------------
Version 2.2 (1998) by Frankie Arzu. 

First, I want to thanks  Stone, Jon  <jdstone@ingr.com> for fixing some printing problems,
he rewrote most of the printing code.  He also added support for English and Metric units.
I added the File->Page_Setup where page margins can be specify.
---------------------------------------------------------------------------------------------------------------------------------------
Version 2.1 (1997) by Frankie Arzu. 
Support to load other common airfoil formats found in the UIUC database. (*.dat).
---------------------------------------------------------------------------------------------------------------------------------------
Version 2.0 (1997) by Frankie Arzu. 
Multi Page printing, Station Lines, Able to change camber and thickness. 
---------------------------------------------------------------------------------------------------------------------------------------
Version 1.0 (1995) by John Garnham. Original Code in Visual C++.

MENU DESCRIPTION

FILE Menu

New, Open,
Save, Save As: 	Loads and Save template definitions and airfoil coordintates.
Print, 
Print Preview: 	Normal Printing Functions!!
Print Setup:	Setup printer parameters (Paper size, orientation, etc.)
Page Setup:	Setup page Margins. You can specify Top, Left and Right
		margins, as well as an extra Overlapping parameter 		(Lees than the right margin). The Overlap is useful to 		align big templates printed in several pages.

SECTION Menu

Choose:		Choose the airfoil to use.
Chord:		Specify chord lenght.
Thickness:	Change thickness of the airfoil (% of Chord)
Camber:		Change camber of the airfoil (% of Chord)
LE Balsa:	Width of the LE block to use.
Skin Thickness:	Specify the skin thickness.

LAYOUT Menu

Foam:		Specify the dimensions of the Foam block to use.
		Thickness is the vertical height of the foam block, 		while "height" is where the center line of the airfoil 		will be place from the bottom of the block.
Leadings:	Specify the length of the LE and TE ramps.
WashOut:	Wash Out  to be use (can be negative to give Wash In!!)
Stations:	Number of stations to be plot in the template.
Wire:		Thickness of the wire cut, this parameter  is at least 		the diameter of the wire. To compute it you have to  		make several cuts in the scrap foam and measure the 		diameter  of the cut when the wire is hot.  This is why
		if  you zoom the LE of the template, the lower template 		will look shifted to the left the same distance as the 		wire diameter.

Lower Core:	Hides/Show the lower line of the core.


AIRFOILS

You can download the airfoils from many places in the internet, I specially recommend the 
UIUC Airfoil database at   http://amber.aae.uiuc.edu/~m-selig/.   

Preferable you can download  .COR format.  The database has several file with different
formats, all with the same extension (.DAT).  Profile can load and recognize the most
common formats of this DAT files, BUT NOT ALL. If the program displays crazy things, you
know that it did not recognize well the format. All this files are TEXT, so you can edit
them in the window notepad.exe program.


FOAM CUTING

This program was design to help plot the airfoil templates.  

First you have to cut two lower core templates and two upper core templates. The program will
automatically compensate the lower core to take into count the wire diameter.

To cut the core, first you have to cut the LOWER part of the core and then the UPPER part!!!
Otherwise, the wire compensation in the template will not work OK.
