Верстак PartDesign
Introduction
PartDesign Workbench предоставляет расширенные инструменты для моделирования сложных твердых деталей. Он в основном сосредоточен на создании механических деталей, которые можно изготовить и собрать в готовый продукт. Тем не менее, созданные тела могут быть использованы в целом для любых других целей, таких как архитектурный дизайн, FE анализ или 3D-печати.
PartDesign Workbench неразрывно связан с Sketcher Workbench. Пользователь обычно создает эскиз, затем использует инструмент PartDesign Pad для его выдавливания и создания основного тела, а затем это тело дополнительно модифицируется.
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.
Инструменты
Все инструменты проектирования деталей находятся в меню Part Design и на панели инструментов PartDesign, которая появляется при загрузке рабочей среды проектирования деталей.
Инструменты структуры
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.
Part Design Helper tools
- Create body: Creates a Body 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.
- Edit sketch: Edit the selected Sketch.
- Map sketch to face: Maps a sketch to a previously selected plane or a face of the active body.
Part Design Modeling tools
Datum tools
- Create a datum point: creates a datum point in the active body.
- Create a datum line: creates a datum line in the active body.
- Create a datum plane: creates a datum plane in the active body.
- Create a local coordinate system: creates a local coordinate system attached to datum geometry in the active body.
- Create a shape binder: creates a shape binder in the active body.
- Create a clone: creates a clone of the selected body.
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.
- Create an additive primitive: adds an additive primitive to the active body.
- Additive box: creates an additive box.
- Additive cone: creates an additive cone.
- Additive cylinder: creates an additive cylinder.
- Additive ellipsoid: creates an additive ellipsoid.
- Additive prism: creates an additive prism.
- Additive sphere: creates an additive sphere.
- Additive torus: creates an additive torus.
- Additive wedge: creates an additive wedge.
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.
- Create a subtractive primitive: adds a subtractive primitive to the active body.
- Subtractive box: adds a subtractive box to the active body.
- Subtractive cone: adds a subtractive cone to the active body.
- Subtractive cylinder: adds a subtractive cylinder to the active body.
- Subtractive ellipsoid: adds a subtractive ellipsoid to the active body.
- Subtractive prism: adds a subtractive prism to the active body.
- Subtractive sphere: adds a subtractive sphere to the active body.
- Subtractive torus: adds a subtractive torus to the active body.
- Subtractive wedge: adds a subtractive wedge to the active body.
Transformation tools
These are tools for transforming existing features. They will allow you to choose which features to transform.
- Mirrored: mirrors one or more features on a plane or face.
- Linear Pattern: creates a linear pattern based on one or more features.
- Polar Pattern: creates a polar pattern of one or more features.
- Create MultiTransform: creates a pattern with any combination of the other transformations.
Dress-up tools
These tools apply a treatment to the selected 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(s).
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.
- 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.
- Involute gear: creates an involute gear profile that can be used by a Pad.
Contextual Menu tools
- Set tip: redefines the tip, which is the feature exposed outside of the Body.
- Move object to other body: moves the selected sketch, datum geometry or feature to another 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.
Preferences
- Preferences...: Preferences available in PartDesign Tools.
