The [[Image:Workbench_Surface.svg|24px]] [[Surface_Workbench|Surface Workbench]] introduced in FreeCAD 0.17 provides tools to create and modify simple [https://en.wikipedia.org/wiki/Non-uniform_rational_B-spline NURBS surfaces]. These tools have a similar functionality to the {{Button|[[File:Part Builder.svg|16px]] [[Part_Builder|Part Builder]]}} tool when the {{MenuCommand|Face from edges}} option is used. However, unlike that tool, the tools of the Surface Workbench are parametric and provide additional options. In this respect, the tools in this workbench are similar to {{Button|[[File:PartDesign_AdditiveLoft.svg|16px]] [[PartDesign_AdditiveLoft|PartDesign AdditiveLoft]]}} and {{Button|[[File:PartDesign_AdditivePipe.svg|16px]] [[PartDesign_AdditivePipe|PartDesign AdditivePipe]]}}.

The Surface Workbench intends to create faces with shapes, which is not possible to do with the standard tools in other workbenches. The OCCT kernel gives as example a rectangular box with a rounded corners of different radii.

Логотип верстака Surface

Введение

Верстак Surface предоставляет инструменты для создания и изменения простых поверхностей NURBS. Эти инструменты имеют функциональность, похожую на инструменты Part Builder при использовании опции Face from edges. Однако, в отличие от этих инструментов, Верстак Surface параметрический и даёт дополнительные опции. В этом отношении, инструменты этого верстака похожи на PartDesign AdditiveLoft и PartDesign AdditivePipe.

Некоторые из предоставляемых функций:

  • Создание поверхностей из граничных ребер.
  • Выравнивание кривизны от соседних граней.
  • Ограничение поверхностей дополнительными кривыми и вершинами.
  • Расширение лица.
  • Можно использовать сетку в качестве шаблона для создания сплайновых кривых на ее поверхности.

Применение

Верстак Surface предназначен для создания граней с формами, что невозможно сделать стандартными инструментами в других верстаках.

Surface created with sketches placed in datum planes with the tools of the PartDesign Workbench

The Surface Workbench integrates with other workbenches of FreeCAD. The above example was created from Sketches placed on PartDesign Datum planes in the PartDesign Workbench. The design can be fully parametric if all datum planes and sketches are defined accordingly. In most cases it is sufficient to draw a closed sketch to define the boundary of a face, and then use different options to further modify its shape.

The generated surface cannot be placed inside a PartDesign Body. However, the generated surface can be contained inside a Std Part together with the associated PartDesign Body that holds the datum planes and sketches. The non-parametric Part Builder tool can then be used in order to create a shell and finally a solid.

Инструменты

  • Filling: fills a series of boundary curves with a surface.
  • Sections: creates a surface from edges that represent transversal sections of surface.
  • Extend face: extrapolates the surface at the boundaries with its local U parameter and V parameter.
  • Blend Curve: creates a Bezier curve between two edges, with desired continuity.
