Draft Facebinder

Description
The Facebinder tool creates a surface object from the selected faces of a solid object. It is parametric, meaning that if you modify the original object, the Facebinder updates accordingly. If you move and rotate the Facebinder, it will stay linked to the original faces.

It can be used to create an extrusion from a collection of faces from other objects. A typical use is in architectural design to build an object that covers several walls, for example, a wall paper, or wall finish.



How to use

 * 1) Pick one face, or hold  and pick several faces, from solid objects.
 * 2) Press the  button, or press  then  keys.

The Facebinder can be edited by double clicking on the element in the tree view. Then you can change the faces that are part of the object.
 * To add a face, click on a face of a solid object in the 3D view, and then click on the button.
 * To remove a face, select one of the sub-elements in the list, and then click on the button.
 * Press or the  button to complete the edition.

Options
This object has no options when it's being created. Only selected faces will be used to create the Facebinder object.

Data

 * : specifies an extrusion thickness to apply to all faces of the shape.
 * : if it is it tries to fuse the internal intersections of the Facebinder when it extruded.
 * : if it is it tries to perform a topological sewing operation on the Facebinder when it extruded.

View

 * : specifies a Draft Pattern with which to fill the face of the shape. This property only works if is "Flat Lines".
 * : specifies the size of the Draft Pattern.

Scripting

The Facebinder tool can be used in macros and from the Python console by using the following function:

A is a list of tuples; each tuple contains as first element an, and as second element a list (or tuple) of strings; these strings indicate the names of the sub-elements (faces) of that object.
 * Creates a object from the given, which is a list of s as returned by . Only selected faces are taken into account.
 * can also be a.

The thickness of the Facebinder can be added by overwriting its attribute; the value is entered in millimeters.

The placement of the Facebinder can be changed by overwriting its attribute, or by individually overwriting its  and  attributes.
