PartDesign: Nuovo schizzo, Mappa uno schizzo, Riposiziona lo schizzo

Descrizione

Questo strumento crea un nuovo schizzo.

Si noti che PartDesign ha il proprio strumento nuovo schizzo, quando si lavora su un corpo di PartDesign è preferibile usare quello strumento.

Utilizzo

1. If the sketch should be attached to existing geometry: select an object with a shape, or one or more vertices, edges, and/or faces, and/or a plane.
2. There are several ways to invoke the tool:
   • Press the Create sketch button.
   • Select the Sketch → Create sketch option from the menu.
3. If geometry has been selected:
   1. The Sketch attachment dialog opens.
   2. Select an attachment method from the dropdown list. Or select Don't attach to ignore the selection.
   3. Press the OK button.
4. If there is no selection, or Don't attach has been selected in the previous step:
   1. The Choose orientation dialog opens.
   2. Specify the plane for the orientation. The plane is relative to the local coordinate system the sketch is in:
      • If the Reverse direction checkbox is not checked:
        • Top: XY-Plane
        • Front: XZ-Plane
        • Right: YZ-Plane
      • If the Reverse direction checkbox is checked:
        • Bottom: XY-Plane
        • Rear: XZ-Plane
        • Left: YZ-Plane
   3. Optionally change the Offset. The offset is measured along the Z, Y or X axis of the local coordinate system.
   4. Press the OK button.
5. A sketch is created.
6. The sketch is put in edit mode and the Sketcher Dialog opens.
7. To finish edit mode see Sketcher LeaveSketch.

Notes

• Existing sketches can be attached to (different) object(s) with Sketcher MapSketch or detached and reoriented with Sketcher ReorientSketch.
