04/08/2000 v3.00

The first release of CompuFoil2000.

04/20/2000 v3.02

Created workaround for Windows NT4.0 help file bug which would report that the help file is the incorrect type. I fixed a few holes in the help file. I Added the ability to load a file from the Planform Creation Wizard. If you have a planform loaded within CompuFoil and you use the wizard, you can change it and then when you click the OK button, the planform shape will be updated to your change within CompuFoil. If you don't have and airfoil loaded when you run the wizard, and you then load it with the wizard, you can then save the file to disk.

04/21/2000 v3.03

 I added support for my new program CC_ORDER.EXE within CompuFoil. This program allows you to securely order items using credit card over email. It will encrypt your order information and add it to the email body for you

04/28/2000 v3.04

 I added support to move jig holes and leading edge round stock using your cursor keys once selected with a double click. Pressing <Enter> will place the hole as well. This ability was inadvertently documented in the help file when the text was copied from the V-Notch section, (documentation bug...). In the true spirit of CompuFoil, I chose to add the functionality rather than simply change the help file

05/04/2000 v3.05a

 I have added the ability to automatically set the remaining holes to the currently selected holes position and size. This is done by double clicking on the hole, manipulating it to where you want it, then right click on it. In the resulting window, check the [X]Set All similar Holes to these Dimensions option.

05/05/2000 v3.06

I have added the ability to specify a negative spar protrusion, (previously only positive protrusion allowed)

05/24/2000 v3.07

I have added the options to automatically size the trailing edge tab such that the airfoil will lie on its the lowest point and the tab. When this option is selected, only a trailing edge tab will be produced.

05/31/2000 v3.08

This change concerns the trailing edge ramp. Previously, the ramp angle was taken from the angle produced by the second coordinate from the trailing edge and the trailing edge. In order to make the resulting angle more consist ant, I have changed this to the points at 95% and 97% back from the leading edge. Furthermore, if the airfoil has a split trailing edge and no sheeting, the ramp will start at the end of the top surface if the ramp is to follow the top surface, or start at the bottom surface end if it is to follow the bottom surface angle. Previously, it always started at the halfway point between the two separated ends

07/11/2000 v3.09

Add double buffering routines to NACA Generator and PlanformWizard as well as TE Flare Wizard to eliminate preview flicker

08/15/2000 v3.10

Added page numbers to printer output for single sheet pages

09/13/2000 v3.11

Add double buffering routines to NACA Generator and PlanformWizard as well as TE Flare Wizard to eliminate preview flicker

12/16/2000 v3.12

I added the ability for the protrude dimension in the spar slot window to influence the location of the spar when you have the option selected to "[X]This spar's depth is referenced from the camber line." By setting the protrusion dimension as negative one half the spar depth, and having this option checked, the spar will always be centered on the mean camber line, no matter where along the airfoil's length it is placed.

10/16/2001 v3.12 - v3.18

Internal modifications

11/14/2001 v3.19

I added an option for Joiner Tube Configuration in the JigHole window. When this is checked, all ribs will have their jig holes at the height that the root rib has them. This will force them to maintain the same relative angle and keep them inline. They will progress at the same relative angle in height if you have a dihedral dimension entered. Always check this option off if you are using the holes for joiner tubes

10/16/2001 v3.20

Previously, when you opened the help file, the Windows help system would disable CompuFoil as long as the help window was open. I managed to work around this odd behavior

05/08/2002 v3.21

When you select a different default coordinate path using the Defaults|Coordinate Path menu, the file open window path will now be automatically reset to reflect the new default path.

11/19/2003 v3.22

Added a Select All button to the Create New Coordinate File window.

02/08/2004 v3.23

Added ability to print wing lengths over 129".  Max is now about 330"
