Wprowadzenie
Ten poradnik ma na celu zapoznanie czytelnika z podstawowym przepływem pracy w środowisku pracy Projekt Części. Czytelnik zobaczy jak tworzyć obiekty 3D na podstawie szkiców, wykonywać operacje odejmowania oraz jak powielać określone cechy we wzorze.



Wymagania

 * FreeCAD w wersji v0.17 lub wyższej.
 * Czytelnik ukończył poradnik Podstawy dla środowiska pracy Szkicownik

Tworzenie geometrii 3D
Celem środowiska roboczego Projekt Części jest umożliwienie użytkownikowi tworzenia geometrii w przestrzeni 3D. W związku z tym jest ono wyposażone w narzędzia do wykorzystania szkiców i przekształcania ich w obiekty 3D.

Aby to osiągnąć, istnieją dwa narzędzia: Wyciągnij oraz  Wyciągnij przez obrót. Obok ich subtraktywnych odpowiedników ( kieszeń i rowek) tworzą większość typowych akcji używanych przez to środowisko pracy.


 * 1) Switch to the PartDesign Workbench
 * 2) With the sketch selected in the tree view, press, choose the default XY-plane, and press . The sketch should appear now inside the Body.
 * 3) Select [[Image:PartDesign_Pad.svg|32px]] Pad
 * 4) Set the distance to 5 mm
 * 5) Select Ok

Another way to create 3D geometry is with the  Revolution tool.




 * 1) Create a new body, and then a sketch based on the image above.
 * 2) The sketch can be on any plane, but should be co-incident with the horizontal axis.
 * 3) Select [[Image:PartDesign_Revolution.svg|32px]] Revolution
 * 4) Set the "Axis" to the "Horizontal Sketch Axis"
 * 5) Set the angle to 360°

Subtracting Features
We'll begin by creating a sketch with the shape we want to subtract.


 * 1) Select the top flat face of the "Revolution"
 * 2) Select [[Image:Sketcher_NewSketch.svg‎‎|32px]] New sketch
 * 3) Select [[Image:Sketcher_External.svg|32px]] External Geometry
 * 4) Approach the edge of the pad. An arc should be highlighted
 * 5) Select the arc. An arc of a different color should appear in the sketch
 * 6) Create a hexagon centered on the same point as the arc and set the radius of the reference circle to 5 mm



Afterwards, we'll proceed to apply a Pocket feature.


 * 1) Select the sketch
 * 2) Select [[Image:PartDesign_Pocket.svg|32px]] Pocket
 * 3) Set the distance to Through all

Pattern Features
Recall the extruded profile that was created at the start of the tutorial.


 * 1) Select the top face of the object
 * 2) Create a new Sketch
 * 3) Create reference geometry linked to the top arm of the figure
 * 4) Create a circle constrained to the center of the reference arc
 * 5) Set its radius to 3 mm
 * 6) Pocket the sketch through all the workpiece

Instead of creating a circle for each hole in the sketch, we will introduce the concept of Pattern Features. These tools operate by replicating a feature in the workpiece that has already been created and that we wish to reproduce in a linear or circular arrangement. We will use a combination of Linear and Polar pattern features simulatneously to obtain the final workpiece.


 * 1) Select the Pocket feature that we just created in the Tree View
 * 2) Select [[Image:PartDesign_MultiTransform.svg|32px]] MultiTransform

In the Combo View we are now asked to introduce the Transformations that we desire. Notice that in the MultiTransform parameters menu we see that FreeCAD has identified the Pocket as the Original feature and a second box requests us to Right click it to introduce the pattern features.


 * 1) Right click the box
 * 2) Select Add Linear Pattern
 * 3) Set the Direction to Vertical Sketch Axis
 * 4) Set length to 10 mm
 * 5) Leave occurrences at 2
 * 6) Click OK
 * 7) Right click the box again to add a Polar Pattern. Notice that the 3D view has now added the linear pattern.
 * 8) Set occurrences to 5
 * 9) Click OK twice

Po wykonaniu tego zadania powinieneś mieć następujący wynik.



If not, re-edit the MultiTransform operation by double clicking on it in the Tree View. Check both pattern features to detect necessary modifications, such as the Axis and if the Direction needs to be reversed.

We are now finished with the basic workflow for the PartDesign Workbench.
