Introduction

零件设计工作台提供了一些高级工具,基于属性编辑方法,来建模复杂实体零件。它主要用于创建机械零件,但是也不局限于机械件。它与草图工作台复杂而紧密地联系在一起。

The PartDesign Workbench uses a feature based methodology. A component is represented by the Body object container. The Body defines a local coordinate system and contains the cumulative features that define the component. Most features are based on parametric sketches and are either additive or subtractive. For example, the Pad tool adds the extruded sketch to the developing solid, the Pocket tool subtracts the extruded sketch. Each feature is cumulative and builds on the result of preceding features. It is also possible to use primitives (Cylinder, Sphere, etc.) as well as solids created outside the Body as features.

See the feature editing page for a more complete explanation of this process, and then see Creating a simple component with PartDesign to get started with creating solids.

The Part Workbench provides an alternative constructive solid geometry (CSG) methodology for building shapes. For a detailed discussion of the Part Workbench versus the Part Design Workbench see Part and Part Design.

Tools

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 Design Helper tools

  • 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.
  • Attach sketch: attaches a sketch to geometry selected from the active body.

Part Design Modeling tools

Additive tools

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

Subtractive tools

These are tools for subtracting material from an existing body.

Boolean

Dress-up tools

These tools apply a treatment to edges or faces.

Transformation tools

These are tools for transforming existing features.
