Why upgrade to CompuFoil3D from CompuFoil2000? After all, CompuFoil2000 has been working well for you right? Aside from the vast list of enhancements below, CompuFoil2000 was maintained to allow for use on the old 16 bit Windows 3.1 operating system. This automatically limited the user to not having many of the conveniences of the modern 32 bit operating system, such as long file names, etc. CompuFoil3D is compiled for use on Windows 2000, XP, Vista, and Win7 operating systems.

CompuFoil3D vs CompuFoil2000
Module	Item	CompuFoil3D	CompuFoil2000
Base Program
	Auto Lightening Hole Generation	Lightening Holes can be automatically generated - automatically avoiding spars. Double click to selectively turn holes on and off within a rib.
	Station Lines	Station lines for both Foam Template as well as use for full rib subdivision	Foam templet type station lines only
	Movable/ Dockable Toolbars	Toolbars may be docked to edges of screen	Turn on/off only
	Long filenames	Full long filename support	Limited to eight characters
	Conic Bulkhead Generating Wizard	Easily generate bulkhead shapes with conic curve edges
	Configurable sheeting	User may define starting/ending ribs	Sheeting applies to all ribs
	Leading edge reinforcing strips	Strips inset at leading edge for reinforcement
	Adjustable line width	User adjustable printed width of lines	Manual editing of .ini file
	Update availability	Automatically checks for updates and handles installation
	Splash screen customization	User may select images to be used for flying planes
	Print Preview	32 tiling configuration options, with up to 100 pages displayed	Two page limit side-by-side
	Leading Edge Roundstock	Selected holes can be "turned off" so as not to print
	Page Numbering	Pages are numbered according to row and column
	VNotches	Selected notches can be "turned off" so as not to print
	Color Configuration	Individual colors for: Dotted lines, Text, Solid lines, Jig Holes, Round Stock, Spar Notch, V-Notch, Hidden item, Selected Item, Highlighted Spar, Highlighted Hole	Dotted, solid and text colors
	Trailing edge stock notch allowance	Allows for rib notch cut into trailing edge stock
	Visual indication of modified/moved leading edge round stock	Altered holes have a 'X' center point rather than "+"
	Common button graphics	Common selection buttons such as "Apply", "Cancel", etc have common bitmaps for quicker reference
Modification Module
	Pressure profiles calculated around surface	Cp plotted in real time as airfoil is altered
	Undo/Redo	Multiple Undo/Redo capacity	Limited to last modification
	Reflex Wizard	Allows for trailing edge reflex
	Multi Rib Flare Wizard	Multiple lofted ribs may be flared	Only individual ribs may be flared
Spar Slots
	Tubular spars	Tubular spars for both surface notches as well as full depth spars	Tubular spars for surface notches only
	Spar highlight identification	Currently selected spar is highlighted for easy identification
	Spar rotation	Spar may be rotated about center to any angle
Jig/Construction Holes
	Possible Number	Five Groups of two holes	Two holes only
	Scope	Configurable starting/ending position	Holes run through all ribs
	Rotation	Rotate holes due to washout about leading edge hole	Holes always rotate relative to leading edge
	Dihedral	Individual dihedral angle for each hole group
	Hole highlight	Current holes being worked on are highlighted
	Visual indication of modified/moved holes	Altered holes have a 'X' center point rather than '+'
3D Rendering	(new to 3D version)
		Render wing as sheeted, skeletal, or line drawing
Lofting
	Dihedral Angle	Each panel may have a separate dihedral angle
	Washout transition	Both Geometric and proportional washout distributions.	Proportional washout transition only
	Auto Tab Height	Automatically adjust building tab heights to generate flat top wing surface
	Scaled Printouts	Print out scaled wing layouts that fit on one page
	Multiple foam template sets	Selection for height adjustment for straight top surface or dihedral angle	Selection for height adjustment for straight top surface only
Geodetic Lofting	(new to 3D version)
	Create ribs that cross from one forward rib to another	Six different rib configurations available
DXF Ouput
	Scaling	User define scaling factor
	Offset	User defined image offset
	Rib Spacing	User defined gap between rib images
CNC-DXF Outline	(new to 3D version)
	Create outline only dxf file.	Generates clean polyline of rib outline, including spar slots for CNC cutter use. May also define cutter offsets. Can generate .dxf file in 3D for milling purposes.
