소개

FreeCAD의 견고한 모델링 기능은 고급 3D 형상 생성 및 조작 기능을 갖춘 전문가급 CAD 시스템인 OpenCASCADE 기술(OCCT) 커널을 기반으로 합니다. 부품 작업대는 OCCT 라이브러리 상단에 있는 레이어로, 사용자가 OCCT 기하학적 기본 요소 및 기능에 접근할 수 있습니다. 기본적으로 설계제도 작업대, 스케치 작업대, 부품 작업대 등의 작업대의 모든 2D 및 3D 도면 기능은 부품 작업대에서 노출되는 이러한 기능을 기반으로 합니다.

부품 작업대와 부품설계 작업대에 대한 자세한 설명은 부품 그리고 부품설계에서 확인할 수 있습니다.

부품 작업대에서 만들어지는 모형들은 비교적 단순합니다; 이 작업대에서는 더 복잡한 형상을 만들기 위해 부울 연산(결합 및 잘라내기)을 사용하도록 고안되었습니다. 이러한 모델링 기법은 구성적 고체 기하학(Constructive Solid Geometry)(CSG) 작업 흐름으로 알려져 있으며 초기 CAD 시스템에서 사용되는 전통적인 방법론이었습니다. 반면, 부품설계 작업대에서는 형상을 만들어 나갈 때 보다 현대적인 방법으로 작업합니다: 이는 파라메트릭하게 정의된 스케치를 사용하여 돌출되어 기본 고체 몸통을 형성한 다음 최종 객체를 얻을 때까지 파라메트릭 변환(특징 편집)을 통해 수정됩니다.

부품 개체는 일관된 부울 연산, 수정 내역 및 파라메트릭 동작과 같은 고급 작업을 허용하므로 메쉬 작업대에서 생성된 메쉬 개체보다 더 복잡합니다.

The Part Workbench is the basic layer that exposes the OCCT drawing functions to all workbenches in FreeCAD.

Tools

The tools are located in the Part menu.

Primitives

These are tools for creating primitive objects.

  • Box: Creates a box.
  • Cone: Creates a cone.
  • Tube: Creates a tube.
  • Create primitives...: A tool to create one of the following primitives:
    • Plane: Creates a plane.
    • Box: Creates a box. This object can also be created with the Box tool.
    • Cylinder: Creates a cylinder. This object can also be created with the Cylinder tool.
    • Cone: Creates a cone. This object can also be created with the Cone tool.
    • Sphere: Creates a sphere. This object can also be created with the Sphere tool.
    • Ellipsoid: Creates a ellipsoid.
    • Torus: Creates a torus. This object can also be created with the Torus tool.
    • Prism: Creates a prism.
    • Wedge: Creates a wedge.

    • Circle: Creates a circular arc.
    • Ellipse: Creates an elliptical arc.
    • Point: Creates a point.
    • Line: Creates a line.
    • Regular polygon: Creates a regular polygon.

Creation and modification

These are tools for creating new and modifying existing objects.

  • Revolve: Creates a solid by revolving an object (not a solid) around an axis.
  • Mirror: Mirrors the selected object across a mirror plane.
  • Fillet: Fillets (rounds) edges of an object.
  • Chamfer: Chamfers edges of an object.
  • Loft: Lofts from one profile to another.
  • Sweep: Sweeps one or more profiles along a path.
  • Section: Creates a section by intersecting an object with a section plane.
  • Offset tools:
    • 3D Offset: Constructs a parallel shape at a certain distance from an original.
    • 2D Offset: Constructs a parallel wire at certain distance from an original, or enlarges/shrinks a planar face.
  • Attachment: Attaches an object to another object.

Boolean

These tools perform boolean operations.

  • Boolean: Performs boolean operations on objects.
  • Cut: Cuts (subtracts) one object from another.
  • Fuse: Fuses (unions) two or more objects.
  • Common: Extracts the common (intersection) part of two objects.
  • Join features:
    • Connect: Connects interiors of walled objects.
    • Embed: Embeds a walled object into another walled object.
    • Cutout: Creates a cutout in a wall of an object for another walled object.
  • Splitting tools:
    • Boolean fragments: Creates all pieces obtained from Boolean operations.
    • Slice apart: Slices and splits an object by intersecting it with other objects.
    • Slice: Slices an object by intersecting it with other objects.
    • XOR: Removes space shared by an even number of objects.

Other tools

  • Import: Imports from *.IGES, *.STEP, or *.BREP files.
  • Export: Exports to *.IGES, *.STEP, or *.BREP files.

Context menu items

  • Appearance: Determines the appearance of a whole object (color, transparency etc.).
