Solidify Face (Solid)
=====================

Dependencies
------------

This node requires FreeCAD_ library to work.

.. _FreeCAD: ../../solids.rst

Functionality
-------------

This node takes a Solid Face (i.e. a Surface trimmed by some edges), and makes
a Solid object from it, by offsetting the face along it's normals. In a way, it
is similar to what "Solidify" node does to mesh.

Solid Face object can be created with nodes from "Make Face" submenu (such as
"Face from Curve"); also any NURBS or NURBS-like surface can be used as a Solid
Face.

Inputs
------

This node has the following inputs:

* **SolidFace**. Solid Face object to be used for Solid generation. This input is mandatory.
* **Offset**. Offset value. The default value is 0.1.
* **Tolerance**. Calculation tolerance. The default value is 0.01.

Parameters
----------

This node has the following parameter:

* **Flat output**. If checked, the node will generate one flat list of Solid
  objects for all lists of input faces. Otherwise, the node will generate a
  separate list of Solid objects for each list of input faces. Checked by
  default.

Outputs
-------

This node has the following output:

* **Solid**. The generated Solid object.

Example of Usage
----------------

Make a Face from a closed NURBS curve, then offset it along normal to make a Solid object:
