Náčrt je stavební blok pro vytváření a editování částí těles. Pracovní postup může být shrnut následovně: nejdříve je vytvořen 2D náčrt, potom je použit nástroj na vytvoření tělesa. V tom okamžiku jsou dostupné následující nástroje:
* '''Pad (Deska)''' který vysune náčrt
* '''Pocket (Kapsa)''' který vytvoří kapsu (prohlubeň) v existujícím tělese
* '''Revolve''' který vytvoří těleso otáčením náčrtu podle osy
* '''Groove'''' který vytvoří drážku v existujícím tělese
V budoucích verzích jsou plánovány další nástroje.

Velmi důležitý v pracovní ploše Díly je koncept '''podpora náčrtu'''. Náčrty mohou být vytvořeny ve standardních rovinách ('''XY''', '''XZ''', '''YZ''' a v rovinách rovnoběžných k nim) nebo na povrchu existujícího tělesa. V tomto posledním případě se těleso stává '''podpůrným''' náčrtem. Některé nástroje budou pracovat pouze s náčrty které mají podpůrné těleso, např. '''Pocket (Kapsa)''' - bez podpůrného tělesa by nebylo z čeho odebírat materiál!

The PartDesign Workbench is intrinsically related to the [[Sketcher_Workbench|Sketcher Workbench]]. The user normally creates a Sketch, then uses the [[PartDesign_Pad|PartDesign Pad]] tool to extrude it and create a basic solid, and then this solid is further modified.
<div class="mw-translate-fuzzy">
== Nástroje ==
</div>


While the [[Image:Workbench_Part.svg|24px]] [[Part_Workbench|Part Workbench]] is based on a [[constructive_solid_geometry|constructive solid geometry]] (CSG) methodology for building shapes, the PartDesign Workbench uses a parametric, feature editing methodology, which means a basic solid is sequentially transformed by adding features on top until the final shape is obtained. See the [[feature_editing|feature editing]] page for a more complete explanation of this process, and then see [[Creating_a_simple_part_with_PartDesign|Creating a simple part with PartDesign]] to get started with creating solids.

The bodies created with PartDesign are often subject to the [[Topological_naming_problem|topological naming problem]] which causes internal features to be renamed when the parametric operations are modified. This problem can be minimized by following the best practices described in the [[feature_editing|feature editing]] page, and by taking advantage of datum objects as support for sketches and features.

These tools are in fact not part of the PartDesign Workbench. They belong to the [[Std_Base|Std Base]] system. They were developed in v0.17 with the intention that they would be useful to organize a model, and create [[Assembly|assemblies]]; as such, they are very useful when working with bodies created with this workbench.

==== Body Visibility Management ====


=== Part Design Helper tools ===
A body will present by default its most recent feature to the outside. This feature is defined by default as the tip. A good analogy is the expression ''the tip of the iceberg'': only the tip is visible above the water, most of the iceberg's mass (the other features) is hidden. As a new feature is added to the body, visibility of the previous feature is turned off, and the new feature becomes the tip.


*[[File:PartDesign_Body.svg|32px]] [[PartDesign_Body|Create body]]: creates a [[Body|Body]] object in the active document and makes it active.
There can only be one feature visible at a time. It is possible to toggle the visibility of any feature in the body, by selecting it in the Model tree and pressing the spacebar, in effect going back in the history of the body.


*[[File:Sketcher_NewSketch.svg|32px]] [[PartDesign_NewSketch|Create sketch]]: creates‎ a new sketch on a selected face or plane. If no face is selected while this tool is executed, the user is prompted to select a plane from the Tasks panel. The interface then switches to the [[Sketcher_Workbench|Sketcher Workbench]] in sketch editing mode.
==== Body Origin ====


* [[File:Sketcher_EditSketch.svg|32px]] [[Sketcher_EditSketch|Edit sketch]]: edit the selected Sketch.
The body has an Origin which consists of reference planes (XY, XZ, YZ) and axes (X, Y, Z) that can be used by sketches and features. Sketches can be attached to Origin planes, and they no longer need to be mapped to planar faces for features based on them to be added or subtracted from the model.


* [[File:Sketcher_MapSketch.svg|32px]] [[Sketcher_MapSketch|Map sketch to face]]: maps a sketch to a previously selected plane or a face of the active body.
==== Moving and Reordering Objects ====


* [[File:Sketcher_ValidateSketch.svg|32px]] [[Sketcher_ValidateSketch|Validate sketch]]: verifies the tolerance of different points and adjusts them.
It is possible to temporarily redefine the tip to a feature in the middle of the Body tree to insert new objects (features, sketches or datum geometry). It is also possible to reorder features under a Body, or to move them to a different Body. Select the object and right-click to get a contextual menu that will offer both options. The operation may be prevented if the object has dependencies in the source Body, such as being attached to a face. To move a sketch to another Body, it should not contain links to external geometry.


=== Datum Geometry ===
=== Part Design Modeling tools ===


==== Datum tools ====
Datum geometry consists of custom planes, lines, points or externally linked shapes. They can be created for use as reference by sketches and features. There is a multitude of attachment possibilities for datums.


*[[File:PartDesign_Point.svg|32px]] [[PartDesign_Point|Create a datum point]]: creates a datum point in the active body.
=== Cross-referencing ===


*[[File:PartDesign_Line.svg|32px]] [[PartDesign_Line|Create a datum line]]: creates a datum line in the active body.
It is possible to cross-reference elements from a body in another body via datums. For example the datum shape binder allows to copy over faces from a body as reference in another one. This should make it easy to build a box with fitting cover in two different bodies. FreeCAD helps you to not accidentally link to other bodies and queries your intent.


*[[File:PartDesign_Plane.svg|32px]] [[PartDesign_Plane|Create a datum plane]]: creates a datum plane in the active body.
=== Attachment ===


*[[File:PartDesign_CoordinateSystem.svg|32px]] [[PartDesign_CoordinateSystem|Create a local coordinate system]]: creates a local coordinate system attached to datum geometry in the active body.
Object attachment is not a specific PartDesign tool, but rather a Part utility introduced in v0.17 that can be found in the Part menu. It is heavily used in the PartDesign workbench to attach sketches and reference geometry to the standard planes and axes of the Body. Very extensive ways of creating datum points, lines and planes are available. Optional attachment offset parameters make this tool very versatile.


*[[File:PartDesign_ShapeBinder.svg|32px]] [[PartDesign_ShapeBinder|Create a shape binder]]: creates a shape binder referencing geometry from a single parent object.
More info can be found in the [[Part Attachment|Attachment]] page.


*[[File:PartDesign_SubShapeBinder.svg|32px]] [[PartDesign_SubShapeBinder|Create a sub-object(s) shape binder]]: creates a shape binder referencing geometry from one or more parent objects.
=== Advice for creating stable models ===


*[[File:PartDesign_Clone.svg|32px]] [[PartDesign_Clone|Create a clone]]: creates a clone of the selected body.
The idea of parametric modeling implies that you can change the values of certain parameters and subsequent steps are changed according to the new values. However, when severe changes are made, the model can break. Compared to previous FreeCAD versions breaking can be minimized when you respect the following design principles:


==== Additive tools ====
* Basically, you need to stop mapping sketches to faces - entirely! Place your sketches on standard planes, or on custom datum planes.
* When creating datum geometry, do not base it on the part topology, base it on standard planes/axes and/or sketches.
* Use a "master sketch". That is a preferably not too complicated sketch which contains basic geometric elements of your model. These elements can be referenced when modeling subsequent features. Such a master sketch will often be the first sketch in the Body but it doesn't have to be; in fact you don't even have to use it at all for anything else but being referenced.
* If you inevitably have to reference an intermediate feature, e.g. the result of a thickness operation, use the first reference possible in the list of subsequent features where the referenced geometric element occurs. From FreeCAD 0.17 on you don't have to use the latest feature. If you take an early feature as reference, all changes to intermediate steps won't break your model.

Introduction

The PartDesign Workbench is intrinsically related to the Sketcher Workbench. The user normally creates a Sketch, then uses the PartDesign Pad tool to extrude it and create a basic solid, and then this solid is further modified.

While the Part Workbench is based on a constructive solid geometry (CSG) methodology for building shapes, the PartDesign Workbench uses a parametric, feature editing methodology, which means a basic solid is sequentially transformed by adding features on top until the final shape is obtained. See the feature editing page for a more complete explanation of this process, and then see Creating a simple part with PartDesign to get started with creating solids.

A more detailed discussion of Part workbench versus Part Design workbench can be found here: Part and Part Design.

The bodies created with PartDesign are often subject to the topological naming problem which causes internal features to be renamed when the parametric operations are modified. This problem can be minimized by following the best practices described in the feature editing page, and by taking advantage of datum objects as support for sketches and features.

Nástroje

The Part Design tools are all located in the Part Design menu and the PartDesign toolbar that appear when you load the Part Design workbench.

Structure tools

These are tools to organize the Model tree.

  • Part: adds a new Part container in the active document and makes it active.
  • Group: adds a Group in the active document's Model tree.

These tools are in fact not part of the PartDesign Workbench. They belong to the Std Base system. They were developed in v0.17 with the intention that they would be useful to organize a model, and create assemblies; as such, they are very useful when working with bodies created with this workbench.

  • Part: adds a new Part container in the active document and makes it active.
  • Group: adds a Group container in the active document, which allows organizing the objects in the tree view.

Part Design Helper tools

  • Create body: creates a Body object in the active document and makes it active.
  • Create sketch: creates‎ a new sketch on a selected face or plane. If no face is selected while this tool is executed, the user is prompted to select a plane from the Tasks panel. The interface then switches to the Sketcher Workbench in sketch editing mode.
  • Map sketch to face: maps a sketch to a previously selected plane or a face of the active body.
  • Validate sketch: verifies the tolerance of different points and adjusts them.

Part Design Modeling tools

Datum tools

Additive tools

These are tools for creating base features or adding material to an existing solid body.

  • Pad: extrudes a solid from a selected sketch.
  • Revolution: creates a solid by revolving a sketch around an axis. The sketch must form a closed profile.
  • Additive loft: creates a solid by making a transition between two or more sketches.
  • Additive pipe: creates a solid by sweeping one or more sketches along an open or closed path.

Subtractive tools

These are tools for subtracting material from an existing body.

  • Pocket: creates a pocket from a selected sketch.
  • Hole: creates a hole feature from a selected sketch. The sketch must contain one or multiple circles.
  • Groove: creates a groove by revolving a sketch around an axis.
  • Subtractive loft: creates a solid shape by making a transition between two or more sketches and subtracts it from the active body.
  • Subtractive pipe: creates a solid shape by sweeping one or more sketches along an open or closed path and subtracts it from the active body.
  • Subtractive helix: creates a solid shape by sweeping a sketch along a helix and subtracts it from the active body.

Transformation tools

These are tools for transforming existing features.

  • Mirrored: mirrors one or more features.
  • Create MultiTransform: creates a pattern by combining any of the transformations mentioned above, as well as the Scaled transformation.
    • Scaled: scales one or more features. This is not available as a separate transformation tool.

Dress-up tools

These tools apply a treatment to edges or faces.

  • Fillet: fillets (rounds) edges of the active body.
  • Chamfer: chamfers edges of the active body.
  • Draft: applies an angular draft to selected faces of the active body.
  • Thickness: creates a thick shell from the active body and opens selected face.

Boolean

  • Boolean operation: imports one or more Bodies or PartDesign Clones into the active body and applies a Boolean operation.

Extras

Some additional functionality found in the Part Design menu:

  • Migrate: migrates files created with older FreeCAD versions. If the file is pure PartDesign feature-based, migration should succeed. If the file contains mixed Part/Part Design/Draft objects, the conversion will most likely fail.
  • Sprocket: creates a sprocket profile that can be padded.
  • Involute gear: creates an involute gear profile that can be padded.
  • Shaft design wizard: Generates a shaft from a table of values and allows to analyze forces and moments. The shaft is made with a revolved sketch that can be edited.

Context Menu items

  • Set tip: redefines the tip, which is the feature exposed outside of the Body.
  • Move object after other object: allows reordering of the Body tree by moving the selected sketch, datum geometry or feature to another position in the list of features.

Items shared with the Part workbench

  • Appearance: determines appearance of the whole part (color transparency etc.).

Preferences

  • Preferences: preferences available for PartDesign Tools.
  • Fine tuning: some extra parameters to fine-tune PartDesign behavior.
