SheetMetal SketchOnSheet/fr

Description
La commande SheetMetal SketchOnSheet découpe un trou dans la tôle à partir d'un sketch.

In contrast to the PartDesign Pocket command, where holes are just cut along the sketch normal (local z axis), this tool acts as if it would unfold the sheet metal object, cut the holes, and refold the object.

Utilisation

 * 1) Select a planar face
 * 2) Select a coplanar [[Image:Workbench_Sketcher.svg|16px]] sketch (i.e. lying on the same plane) for the hole layout (preferably from the tree view).
 * 3) *Note: Don't forget the / key!
 * 4) Activate the [[Image:SheetMetal_SketchOnSheet.svg|16px]] Sketch On Sheet metal command using the:
 * 5) * button
 * 6) * drop down menu
 * 7) * keyboard shortcut: then

Preparation
This thingamajg is made of a folded sheet metal object with holes added. And so one open contour sketch for the sheet metal and one sketch for the hole layout have to be prepared in advance. One straight line of the first sketch must be coplanar to the other sketch plane, this will result in coplanar sketch and face used in the next steps.



Workflow

 * 1) Create a folded sheet metal object
 * 2) Select the contour sketch [[Image:SheetMetal_SketchOnSheet-02.png|240px]]
 * 3) Press the  button or use the keyboard shortcut:  then  [[Image:SheetMetal_SketchOnSheet-03.png|240px]]
 * 4) Cut some holes
 * 5) Select the planar face
 * 6) Select the hole layout sketch [[Image:SheetMetal_SketchOnSheet-04.png|240px]]
 * 7) Press the  button or use the keyboard shortcut:  then  [[Image:SheetMetal_SketchOnSheet-05.png|240px]]  Done!
 * 8) Some hints
 * 9) Check if the folded object's thickness is built to the right side. [[Image:SheetMetal_SketchOnSheet-06.png|240px]]  The  yellow contour should lie on the top face of the bottom fold (as shown).  To reverse direction set the value of Bend Side property (Outside <-> Inside).
 * 10) Hole shapes not touching the used planar face won't cut holes into the folded object.  [[Image:SheetMetal_SketchOnSheet-07.png|240px]] The lower rectangle which is hardly touching said face does cut a hole while the upper slot shape doesn't.
