Exercice 3. Cr\u00e9er une grille de poteaux<\/h1>\n\n

Cet exercice montre comment cr\u00e9er dans Grasshopper des poteaux de VisualARQ ordonn\u00e9s sur une grille.<\/p>\n\n

Il utilise un composant de Grille rectangulaire, mais vous pouvez utiliser tout autre composant de grille (Hexagonale<\/em>,\u00a0Radiale<\/em>,\u00a0Carr\u00e9e<\/em>\u00a0ou\u00a0Triangulaire)<\/em>.<\/p>\n\n

\"Grille<\/p>\n\n

1. Cr\u00e9er la grille :<\/h3>\n\n
    \n\n
  • 1. Faites glisser un composant de grille rectangulaire (Rectangular Grid<\/strong>) (Vector Tab > Grid)\u00a0\"Rectangular sur la grille de Grasshopper. Ce composant poss\u00e8de plusieurs entr\u00e9es qui d\u00e9finissent le nombre de cellules de la grille (Ex, Ey<\/em><\/strong>) et les dimensions des cellules (Sx, Sy<\/em><\/strong>).<\/li>\n\n
  • 2. Utilisez plusieurs composants Number Slider<\/strong> pour d\u00e9finir les valeurs de ces param\u00e8tres. La sortie C<\/strong><\/em> d\u00e9termine les limites de la cellule de grille et la sortie P<\/strong><\/em> d\u00e9termine les points des sommets de la grille.<\/li>\n\n<\/ul>\n\n

    2. Ins\u00e9rer les poteaux<\/h3>\n\n
      \n\n
    1. Faites glisser un composant de poteau (Column<\/strong>) \"VA_Column\"sur la grille de Grasshopper. Ce composant a deux entr\u00e9es :\n\n
        \n\n
      • P : <\/strong>Point d’insertion du poteau. D\u00e9termine la position\u00a0<\/strong> du poteau dans le mod\u00e8le.\u00a0<\/li>\n\n
      • O :<\/strong>\u00a0Options pour d\u00e9finir tous les param\u00e8tres du poteau.<\/li>\n\n<\/ul>\n\n<\/li>\n\n<\/ol>\n\n
          \n\n
        • 2. Indiquez les points d’insertion du poteau. Reliez la sortie P du composant de grille rectangulaire \u00e0 l’entr\u00e9e P du composant de poteau. Un poteau sera cr\u00e9\u00e9 sur chaque sommet de la grille.<\/li>\n\n<\/ul>\n\n

          3. D\u00e9finir les param\u00e8tres du poteau<\/h3>\n\n
            \n\n
          • 1. Faites glisser un composant d’options de poteau (Column Options<\/strong> \"ColumnOptions\" sur la grille de Grasshopper. Ce composant poss\u00e8de plusieurs entr\u00e9es pour d\u00e9finir les param\u00e8tres du poteau.<\/li>\n\n
          • 2. Reliez la sortie O<\/em>\u00a0du composant des options du poteau \u00e0 l’entr\u00e9e O<\/em> du composant du poteau.<\/li>\n\n
          • 3. D\u00e9finissez les diff\u00e9rentes Options<\/em> du poteau :\n\n
              \n\n
            • (S<\/em>) \u00a0<\/em>Style<\/span> de poteau :\"Column<\/strong>\u00a0Vous pouvez placer un composant de style<\/em> de poteau (Column Style)\u00a0sur la grille, et le relier \u00e0 l’entr\u00e9e S<\/em> des options du poteau (Column Options<\/em>). Ce composant de style<\/em> poss\u00e8de un style de standard par d\u00e9faut. Pour assigner un style diff\u00e9rent, cliquez avec le bouton de droite sur ce composant et s\u00e9lectionnez l’option \u00ab\u00a0Set one Column style<\/em>\u00a0\u00bb dans la liste. Grasshopper sera masqu\u00e9 jusqu’\u00e0 ce que vous s\u00e9lectionniez un style de poteau dans la liste affich\u00e9e dans la bo\u00eete de dialogue. Cette liste affiche les styles de Poteau disponibles dans le document de Rhino ouvert. (Pour modifier ou cr\u00e9er des styles de poteau, minimisez la fen\u00eatre de Grasshopper<\/em> et ouvrez la bo\u00eete de dialogue Styles de poteau<\/em> avec la commande _vaPoteauStyles<\/em>)<\/li>\n\n
            • (P<\/em>) Profil du poteau (Column\u00a0\u00a0Profile)<\/span><\/em><\/strong> : <\/em><\/em>Le profil de la poteau d\u00e9termine la forme de la section du poteau. Ce profil doit correspondre au profil de style de poteau actuel, sinon Grasshopper d\u00e9tectera une erreur et le poteau ne sera pas cr\u00e9\u00e9.<\/li>\n\n
            • (A<\/em>) Alignement du poteau (Column\u00a0\u00a0Align)<\/span><\/em><\/strong> :\u00a0\"9\u00a0<\/em>L’alignement du poteau d\u00e9termine la position du point d’insertion du poteau en fonction de la forme de son profil. D\u00e9placez un composant d’alignement de poteau (Column Alignment<\/em>) sur la grille et reliez-le \u00e0 l’entr\u00e9e A des options du poteau. Cliquez sur le composant d’alignement<\/em> et s\u00e9lectionnez une des neuf options : (0=Sup\u00e9rieur gauche, 1=Sup\u00e9rieur milieu, 2=Sup\u00e9rieur droite, 3=Milieu gauche, 4=Centre,\u00a05=Milieu droite, 6=Inf\u00e9rieur gauche, 7=Inf\u00e9rieur milieu et 8=Inf\u00e9rieur droite<\/em>).<\/li>\n\n
            • (O<\/em>) D\u00e9calage d’alignement du poteau (Column Alignment Offset<\/em>) <\/strong>: <\/em>Cette valeur d\u00e9finir la distance entre le poteau et son point d’insertion.<\/li>\n\n
            • (R) Rotation <\/em><\/strong>: <\/em>Cette valeur d\u00e9finit la rotation du profil du poteau dans le plan XY.<\/li>\n\n
            • (H) Hauteur <\/em><\/strong>: <\/em>Hauteur du poteau.<\/li>\n\n<\/ul>\n\n<\/li>\n\n<\/ul>\n\n
