Mesh Workbench/ko

소개

메쉬 작업대에서는 삼각형 메쉬를 처리합니다.메쉬는 꼭지점과 가장자리로 연결된 삼각형 면으로 구성된 특별한 유형의 3D 개체입니다.

Sketchup, Blender, Maya 및 3D Studio Max와 같은 많은 3D 응용 프로그램은 메쉬를 기본 유형의 3D 개체로 사용합니다. 메쉬는 꼭지점(점), 모서리 및 삼각형 면만 포함하는 매우 단순한 개체이므로 생성, 수정, 세분화, 늘리기가 매우 쉽고 세부 정보 손실 없이 한 응용 프로그램에서 다른 응용 프로그램으로 쉽게 전달할 수 있습니다. 이러한 이유로 메쉬는 영화, 애니메이션 및 이미지 생성을 다루는 응용 프로그램에서 선택되는 3D 객체 유형인 경우가 많습니다.

그러나 엔지니어링 메쉬 분야에서는 다음과 같은 큰 한계가 있습니다: 곡면을 정확하게 정의할 수 없습니다. 이것이 FreeCAD가 대신 Brep에 의존하는 이유입니다. 메쉬 워크벤치는 메쉬를 직접 조작하는 몇 가지 명령을 제공하지만, 3D 메쉬 데이터를 가져와 솔리드로 변환하여 부품 작업대또는 부품설계 작업대와 함께 사용하는 데 가장 많이 사용됩니다.

도구

All Mesh Workbench tools can be accessed from the Meshes menu. Almost all are also available in one of the Mesh toolbars.

• Import mesh...: Imports a mesh object from a file.

• Export mesh...: Exports a mesh object to a file.

• Create mesh from shape...: Creates mesh objects from shape objects.

• Refinement...: Remeshes a mesh object.

• Analyze
  • Evaluate and repair mesh...: Evaluates and repairs a mesh object.
  • Face info: Shows information about faces of mesh objects.
  • Curvature info: Shows the absolute curvature of curvature objects at selected points.
  • Check solid mesh: Checks if a mesh object is solid.
  • Boundings info...: Shows the bounding box coordinates of a mesh object.

• Curvature plot: Creates Mesh Curvature objects for mesh objects.

• Harmonize normals: Harmonizes the normals of mesh objects.

• Flip normals: Flips the normals of mesh objects.

• Fill holes...: Fills holes in mesh objects.

• Close hole: Fills selected holes in mesh objects.

• Add triangle: Adds faces along a boundary of an open mesh object.

• Remove components...: Removes faces from mesh objects.

• Remove components by hand...: Removes components from mesh objects.

• Create mesh segments...: Creates separate mesh segments for specified surface types of a mesh object.

• Create mesh segments from best-fit surfaces...: Creates separate mesh segments for specified surface types of a mesh object, and can identify their parameters.

• Smooth...: Smooths mesh objects.

• Decimation...: Reduces the number of faces in mesh objects.

• Scale...: Scales mesh objects.

• Regular solid...: Creates a regular parametric solid mesh object.

• Boolean
  • Union: Creates a mesh object that is the union of two mesh objects.
  • Intersection: Creates a mesh object that is the intersection of two mesh objects.
  • Difference: Creates a mesh object that is the difference of two mesh objects.

• Cutting
  • Cut mesh: Cuts whole faces from mesh objects.
  • Trim mesh: Trims faces and parts of faces from mesh objects.
  • Trim mesh with a plane: Trims faces and parts of faces on one side of a plane from a mesh object.
  • Create section from mesh and plane: Creates a cross section across a mesh object.
  • Cross-sections...: Creates multiple cross sections across mesh objects.

• Merge: Creates a mesh object by combining the meshes of two or more mesh objects.

• Split by components: Splits a mesh object into its components.

• Unwrap mesh: Creates a flat representation of a mesh object.

• Unwrap face: Creates a flat representation of a face of a shape object.

Preferences

There are some export preferences related to Mesh Formats but these are not used by commands belonging to this workbench. They are used by the Std Export command.

Mesh Workbench preferences can be found in the following groups in the Preferences Editor:

• Display: On the Mesh view page several preferences can be set.
• OpenSCAD: The Mesh Union, Mesh Intersection and Mesh Difference commands require OpenSCAD and use the OpenSCAD executable preference to find its executable.

Notes

• More mesh tools are available in the OpenSCAD Workbench.
• See Mesh Scripting to manipulate and create meshes using Python.
• See also FreeCAD and Mesh Import
• See Asymptote to export meshes to the Asymptote format.
