Description
L'outil Hélice additive crée un solide en balayant une esquisse ou un objet 2D sélectionné le long d'une hélice.



Le profil (B) est balayé autour de l'axe (A) afin de produire l'hélice solide (C)

Utilisation

 * 1) Sélectionnez l'esquisse à balayer en hélice. Une face sur le solide existant peut également être utilisée.
 * 2) Appuyez sur le bouton.
 * 3) Définissez les paramètres de l'hélice (voir la section suivante).
 * 4) Inspectez l'hélice dans la fenêtre de vue pour vous assurer que les paramètres n'entraînent pas une hélice auto-sécante.
 * 5) Appuyez sur.

Options
When creating an Additive Helix, the Helix parameters dialogue offers several parameters specifying how the sketch should be swept.



Axis
This option specifies the axis about which the sketch is to be swept.
 * Vertical sketch axis: selects the vertical sketch axis.
 * Horizontal sketch axis: selects the horizontal sketch axis.
 * Construction line: selects a construction line contained in the sketch used by the Helix. The drop down list will contain an entry for each construction line. The first construction line created in the sketch will be labelled Construction line 1.
 * Base (X/Y/Z) axis: selects the X, Y or Z axis of the Body's Origin;
 * Select reference...: allows selection in the 3D view of an edge on the Body, or a datum line.

Mode
This controls what parameters will be used to define the helix, Allowable choices are: Pitch-Height, Pitch-Turns and Height-Turns.

Pitch
The distance between turns in the helix.

Height
The height of the helix (center-center).

Turns
The number of turns in the helix. Define as Height/Pitch

Cone Angle
The rate at which the radius of the helix increase along the axis. Allowable range: [-89°, +89°].

Left handed
If checked, the turning direction of helix is reversed from default clockwise to counterclockwise.

Reversed
If checked, the axis direction of helix is reversed from default.

Update view
If checked, the helix will be shown in the view, and updated automatically on every change of the parameters.

Properties
Below are properties which can be defined after creation of the feature.


 * : The axial distance between two turns.
 * : The total length of the helix (not accounting for the extent of the profile)
 * : The number of turns (do not need to be a whole number)
 * : true or false. See Reversed.
 * : The rate at which the radius of the helix increase along the axis. Allowable range: [-89°, +89°].
 * : The the helix axis
 * : The helix input mode (pitch-height, pitch-turns, turns-height)
 * : Not used (Used in SubtractiveHelix)
 * : If false, the tool will propose an initial value for pitch based on the profile bounding box, so that self intersection is avoided.
 * : true or false. If set to true, cleans the solid from residual edges left by features. See Part RefineShape for more details.
 * : Either a sketch containing a closed contour, or a face.
 * : Not used.
 * : Not used.
 * : Not used.
 * : Not used.
