Description

Example of a filled surface, delimited by four edges located in the XY plane; (left) only the four edges, and (right) one additional curve in space that defines the curvature of the surface

Usage

  1. Make sure you have at lease three edges or curves in space forming a closed contour. For example, these can be created with tools of the Draft Workbench or the Sketcher. Using three edges would create a triangular surface; four edges a quadrilateral surface.
    • Optionally, curves can be drawn inside the closed contour, not necessarily touching the edges. These curves can be used to control the curvature of the resulting surface.
    • Likewise, a number of vertices can be used with the same purpose to indicate where the surface must go through.
  2. Press the Surface filling button.
  3. Inside the Filling section, press Add edge.
  4. Use the pointer to pick the desired edges in the 3D view; a preview of the final shape will be shown after selecting valid edges that form a closed contour.
    • Optionally, to control the curvature of the surface, go to the Unbound edges section, press Add edge, and pick the desired edges from the 3D view.
    • Optionally, to control the curvature by means of vertices, go to the Vertices section, press Add vertex, and pick the desired vertices from the 3D view.
  5. Press OK to complete the operation.

The base edges that form the closed contour, as well as the auxiliary vertices and edges, can belong to 2D curves from Draft or the Sketcher, but can also belong to 3D solid objects such as those created with the Part or PartDesign Workbenches.
