Description

Cette macro crée une hélice autour d'un objet solide quelle que soit sa forme, l'hélice suit toute la surface de l'objet. (Python2 requis)


FCSpring On Surface 00.png

Utilisation

Sélectionnez l'objet (solide), la macro calcule les valeurs par défaut:

  • La valeur de la hauteur du BoundBox de l'objet, la valeur X du centre du BounBox la valeur Y du centre du BoundBox et la valeur de la base de l'objet (bounBox le plus bas).

FCSpring On Surface 02.png

Configuration:

  • Pas : Le pas de l'hélice (Defaut: 1)
  • Height : La hauteur de l'hélice. Par défaut la hauteur est la hauteur du boundBox de l'objet.
  • Precision : Nombre de points par tours de l'objet, maximum 360 (Défaut: 36)

Coordinate Begin:

  • X : La valeur X. Si l'objet est décalé, la valeur de l'axe central X BoundBox est détectée et utilisée par défaut.
  • Y : La valeur Y. Si l'objet est décalé, la valeur de l'axe central Y BoundBox est détectée et utilisée par défaut.
  • Z : La valeur Z. Si l'objet est décalé, la valeur de la hauteur du BoundBox est détectée et utilisée par défaut.

Options:

  • BSpline : Une hélice Bspline est créée.
  • Wire : Une hélice Wire est créée.
  • Points : Un point est créé dans toutes les coordonnées créées pour la construction du Bspline ou Wire
  • Reverse : L'hélice est inversée (par défaut: dans le sens antihoraire)
  • Si la case est cochée, vous pouvez voir la progression dans la vue 3D

Command:

  • Quit : Quitte FCSpring_On_Surface.
  • Ok : lance la création.
