Beschreibung
'Skalieren' - dieser Werkzeug nimmt ein oder mehrere Features als Eingabe (die "Originale") und skaliert sie mit einem gegebenen Faktor. Weil um den Schwerpunkt der gewählten Features skaliert wird, verschwinden sie üblicherweise in den skalierten Versionen. Darum ist es normalerweise nur innerhalb einer Mehrfachtransformation sinnvoll zu skalieren.
A linear pattern and a polar pattern → Scaled the linear pattern with 3 steps (occurrences) and the polar pattern with 12 steps
If there is no previous transformation within the MultiTransform feature, scaled items will be placed at the same position as the base feature. This may result in unexpected shapes if the base feature isn't covered completely by the scaled object. And thus it is not recommended to use Scaled as a single or a first transformation of a MultiTransform feature.
A base feature with a hole → Scaled object with 2 occurrences → Scaled object with 4 occurrences
Seit FreeCAD 0.15 ist diese Funktion nicht mehr direkt verfügbar, aber als Komponente MultiTransform enthalten
Scaling a transformed feature
- Do one of the following:
- The MultiTransform parameters task panel opens.
- Right-click in the Transformations list and select Add scaled transformation from the context menu.
- A Scaled item is added to the list and the task panel is extended at the bottom to allow to set the Factor and Occurrences. See Options for more information.
- Click the OK bar at the bottom to validate the options.
- Click the OK button at the top to finish.
Scaling a single feature
- Select a feature of the current body in the Tree view.
- Do one of the following:
- Press the MultiTransform button.
- Select the Part Design → Apply a pattern → Create MultiTransform option from the menu.
- The MultiTransform parameters task panel opens. See above.
Options
- Factor: The factor to which the last feature is scaled.
- Occurrences: Number of steps from unscaled (1) to Factor (including base and last feature).
- A scaled transformation accepts the number of occurrences of the previous transformation as maximum value or any integer divisor of that number returning an integer result. So
12
,6
,4
,3
, and2
are valid for a Linear or Polar Pattern with 12 occurrences. - A scaled single feature accepts any integer number larger than 1.
- A scaled transformation accepts the number of occurrences of the previous transformation as maximum value or any integer divisor of that number returning an integer result. So
Notes
- The center of scaling is the features's center of gravity and that may cause:
- A growing item to protrude on the opposite side of the parent feature.
- A shrinking item to lose all contact with the parent feature and disappear.
- A shrinking pocket to become an invisible cavity inside the parent feature.
