Popis
Tento nástroj vylepší vybrané objekty jiným způsobem. Není-li vybrán žádný objekt budete vyzváni k jeho výběru.
The Upgrade tool performs things such as creating faces and fusing different elements. This tool works with 2D Draft elements. To fuse 3D solids use Part Union and related Boolean operations of the Part Workbench, and PartDesign Boolean of the PartDesign Workbench.
The counterpart to this tool is the 
Draft Downgrade operation.
Open wire upgraded to a closed wire, then to a face; a closed square upgraded to a face, and then fused with the previous face
Použití
- Vyberte jeden nebo více objektů, které chcete vylepšit
- Stiskněte tlačítko

The selected objects are modified or upgraded according to the following conditions, in order:
- If there are more than one face in the selection, the faces are merged (union).
- If there is only one face in the selection, nothing is done.
- If there is only one open wire in the selection, it gets closed, making a face.
- If there are only edges in the selection, all edges are joined into a wire, and the wire is closed if possible.
- If none of the above is possible, a compound object is created.
It is worth trying to upgrade a selection several times to see if a better shape is obtained. For example:
- Upgrading two Draft Lines connected at one end will result in a non-editable wire.
- Upgrading this element again will add a third line and close the non-editable wire.
- Upgrading this element again will add a face to the closed, non-editable wire.
- Upgrading this element again will turn it into a Draft Wire, which can be fully edited, and all its properties modified.
The resulting wire can be better manipulated than the original lines. The fusion of single lines can also be done directly with the Draft Wire tool. Some fusion operations can also be done with the Part Union tool.
Volby
Vybrané objekty jsou modifikovány/vylepšeny podle následujících podmínek (v daném pořadí):
- je-li ve výběru více než jeden objekt, jsou spojeny jejich plochy (union)
- je-li vybrána pouze jedna plocha, nestane se nic
- je-li ve výběru pouze jeden otevřený drát, bude uzavřen
- jsou-li ve výběru pouze hrany, jsou všechny hrany spojeny do jednoho drátu (pokud možno uzavřeného)
- není-li možná žádná z předchozích operací, je vytvořen složený objekt
Skriptování
Nástroj Vylepšení může být použit ze skriptů Pythonu a z maker takto:
upgrade_list = upgrade(objects, delete=False, force=None) addList, deleteList = upgrade(objects, delete=False, force=None)
- Vylepší daný objekt(y) (může to být objekt nebo seznam objektů).
- Je-li delete True, jsou staré objekty smazány.
- Atribut force může být využit pro určení požadovaného způsobu vylepšení. Může to být: makeCompound, closeGroupWires, makeSolid, closeWire, turnToParts, makeFusion, makeShell, makeFaces, draftify, joinFaces, makeSketchFace, makeWires
- Vrací adresář obsahující dva seznamy, seznam nových objektů a seznam objektů ke smazání
Příklad:
import FreeCAD, Draft Circle = Draft.makeCircle(1000) Rectangle = Draft.makeRectangle(2000, 800) addList1, deleteList1 = Draft.upgrade([Circle, Rectangle], delete=False) fused = addList1[0] Line1 = Draft.makeLine(FreeCAD.Vector(2000, 0, 0), FreeCAD.Vector(2500, 1500, 0)) Line2 = Draft.makeLine(FreeCAD.Vector(2500, 1500, 0), FreeCAD.Vector(3000, -1000, 0)) addList2, deleteList2 = Draft.upgrade([Line1, Line2], delete=False) simple_wire = addList2[0] addList3, deleteList3 = Draft.upgrade(simple_wire, delete=False) closed_wire = addList3[0] addList4, deleteList4 = Draft.upgrade(closed_wire, delete=False) face = addList4[0] addList5, deleteList5 = Draft.upgrade(face, delete=False)
