Overview

The loft tool of two lines or polylines can be created a continuous surface. Requirement are two similar line trains, either both "open" as Lines or both "closed" for example Circles. The lines / lines can be present as Sketch or draft.

The Loft has two parameters, "Ruled" and "Solid", each with a value of either "true" or "false".

If "Ruled" is "true" FreeCAD creates a face, faces or a solid from ruled surfaces. Ruled surface page on Wikipedia.

If "Solid" is "true" FreeCAD creates a solid, if "false" FreeCAD creates a face or faces.

Use

Access is via the menu molding -> freeform surface (in the status bar and in the "balloon help" is "Loft tool" is displayed) or by Ikon.

In the "Tasks" will be two lists: "node / wire" and "free form".

Selection of the elements

In the "node / wire" the available items are displayed. Two elements must be selected one after the first in this list.

Thereafter, with the blue arrow that item is added to the list of "free form".

The selected items must be of the same type, so .

Tip: the active / selected items in the list are displayed in the 3D area as active / selected.

command complete

If both elements are selected, the command can be completed with "OK".

result

From closed lines arise surfaces which might be taken at a superficial look for solids / solids.

If indeed a solid / solid to be created, can be used either when you create the button "Create Solid" or after creating the field properties tab data created the free-form surface of the switch "Solid" by pop be set to "true" / set properly.

The procedure is analogous open polylines.
