The smallest pad was first patterned three times in X direction and then scaled to factor two (so the three occurrences have scaling factor 1.0, 1.5 and 2.0). Then a polar pattern was applied with 8 occurrences.

Since the scaling is done with respect to the center of gravity, in the case of a pad, it is necessary that the pad penetrate also in the main body, otherwise the scaled objects are floating, detached from the body. To have a pad that intersects the main body can be used "two dimensions" type or "simmetric to plane" option.

Note

Since FreeCAD 0.15, this feature is not available directly, but is included as MultiTransform component

Introduction

L'outil text-top=Echelle Echelle : prend un ou plusieurs objet(s) sélectionné(s) comme entrée (les originaux), et, les transformes à un facteur d'échelles donné. Étant donné que l'text-top=Echelle Echelle, se construit autour du centre de gravité, des objets choisis, ils disparaissent habituellement à l'intérieur de la version de l'échelle. Donc, normalement il est seulement judicieux d'utiliser l'text-top=Echelle Echelle, dans le cadre de la fonction text-top=PartDesign_MultiTransform Transformation Multiple.

Options

Lorsque vous utilisez la fonction text-top=Echelle Echelle, la boîte de dialogue des paramètres d'text-top=Echelle Echelle, offre les options suivantes :

Selection des originaux

La fenêtre affiche les originaux, des objets qui doivent être mis à l'text-top=Echelle Echelle. En cliquant sur un objet, il sera ajouté à la liste.

Facteur et Occurrences

Spécifie le nombre et le facteur maximal à donner aux objets, qui vont être mis à l'text-top=Echelle Echelle, (y compris la sélection originale).

Limitations

  • Scaling always happens with the centre of gravity of the feature as the base point.
  • A scaled transformation should not be the first in the list
  • The scaled transformation must have the same number of occurrences as the transformation immediately preceding it in the list
  • See linear pattern feature for other limitations
  • See MultiTransform for more details

The smallest pad was first patterned three times in X direction and then scaled to factor two (so the three occurrences have scaling factor 1.0, 1.5 and 2.0). Then a polar pattern was applied with 8 occurrences.

Since the scaling is done with respect to the center of gravity, in the case of a pad, it is necessary that the pad penetrate also in the main body, otherwise the scaled objects are floating, detached from the body. To have a pad that intersects the main body can be used "two dimensions" type or "simmetric to plane" option.
