Macro FCSpring Helix Variable

Description
This macro creates a spring with customizable, any turn may change the spring configuration can be saved in a file with the extension .FCSpring



Use
This section is used to configuration the spring

Schematic detail of spring configuration



First section, spring configuration
If the function is checked The accuracy is automatically set to 1 (360 points per turn 1 point = 1 degrees)
 * Number of coil : Total of coil to spring. Default = 10
 * Radius of spring : Radius of spring. Default = 20.0
 * Pitch of spring : Pitch of spring general. Default = 15.0
 * Precision of turn : Precision of turn the precision correspond the number of point for 1 turn the coil and is calculate : precision (number points) = (pitch / (360/precision)). Default = 5 (72 points)
 * Begin : Begin angle of the spring first coil.
 * End : End angle of the spring last coil.
 * Ch. : Check box choice for activate the function Begin and End angle of the coil unchecked by default.



Second section, type line

 * BSpline : Type line BSpline.
 * Wire : Type line Wire.
 * Points : Check box point if the check box is activate one point is create of on each point.



Third section, coil special length

 * Numbering of coil : Numbering of coil to modify. (Defaut : none)
 * Pitch of coil : Pitch of coil to modify. (Defaut : none)
 * : Button to accept the modification after select the numbering of coil and modify the pitch of coil.
 * Radius of coil : Radius of coil to modify. (Defaut : none)
 * Text edit : This window displayed all coil modified.



Commands

 * : The Read button open a dialogue box to read a file .FCSpring.
 * : The Save button open a dialogue box to save a file .FCSpring with configuration spring modify or not.
 * : Quit the macro.
 * : Reset the macro to default configuration.
