Surface Sections

Description
Surface Sections is used to create a surface from edges that represent transversal sections of a surface.



Usage

 * 1) Make sure you have at lease two edges or curves in space. For example, these can be created with tools of the Workbench_Draft.svg Draft Workbench or the Workbench_Sketcher.svg Sketcher.
 * 2) Press the  button.
 * 3) Press.
 * 4) Use the pointer to pick the desired edges in the 3D view; a preview of the final shape will be shown after selecting two valid edges.
 * 5) Press  to complete the operation.

Options

 * : press once to start picking edges in the 3D view. Individual lines such as and  can be chosen, as well as any edge from solid objects, like those of  and.
 * : press once to start picking edges in the 3D view; these must edges that were previously selected to create the surface.
 * : open the context menu and select, or press in the keyboard, to remove the currently selected edge in the list.
 * : drag the currently selected element in the list in order to change the order in which it will be processed; the list is processed from top to bottom.
 * Press or  to abort the current operation.

Data

 * : a list of edges that will be used to build the curve.

View

 * : it defaults to ; if set to, it will show an overlay with the control points of the surface.

The Surface Section tool can be used in macros and from the Python console by adding the object. The edges to be used to define the surface must be assigned as a LinkSubList to the attribute of the object.
