Part Helix/cs

Popis
Na této stránce je vysvětleno jak editovat základní parametry šroubovice. Kliknete na ikonu Základní geometrické tvary a na ikonu šroubovice  v rozbalovacím menu pro editování parametrů vytvářené šroubovice. Když jse nastavili všechny parametry, kliknete na tlačítko "Vytvořit" pro vykraeslení šroubovice. Once you have edited all the parameters click the button "create" to draw the helix.

A Part Helix is a parametric shape that can be created with the  Part Primitives command. In the coordinate system defined by its property, the axis of the helix matches the Z axis and its bottom point, the start point, lies on the X axis.



Usage
See Part Primitives.

Example


A Part Helix object created with the scripting example below is shown here.

Properties
See also: Property editor.

A Part Helix object is derived from a Part Feature object and inherits all its properties. It also has the following additional properties:

Data
The object has the same attachment properties as a Part Part2DObject.


 * : The handedness, or direction, of the helix: or . The default is, meaning the helix turns counterclockwise as it goes up.


 * : The distance between two consecutive turns of the helix measured along its Z axis. The default is.
 * : The height of the helix. The default is.
 * : The start radius of the helix. The helix has a constant radius if is.
 * : The number of turns per helix subdivision. The default is, meaning each full turn of the helix is a separate segment. Use to suppress subdivision.
 * : The angle that defines of the outer shape of the helix. Valid range: . The default is . If it is the helix is cylindrical, else it is conical.

Scripting

A Part Helix can be created with the method of the document:


 * Where is the name for the object.
 * The function returns the newly created object.
