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.
