Fasteners Workbench

Introduction
The Fasteners Workbench is an external workbench that can add various fasteners to parts.



Installation

 * 1) Install the Fasteners Workbench via the [[Image:AddonManager.svg|24px]] Addon Manager. For manual installation see Installing more workbenches.
 * 2) Restart FreeCAD.
 * 3) Select the [[Image:Fasteners_workbench_icon.svg|24px]] Fasteners Workbench from the Workbench dropdown list.
 * 4) Optionally change the toolbar and menu layout:
 * 5) Go to:.
 * 6) Select one of the available options:
 * : All fasteners appear in a single toolbar. To see all available buttons use the button to expand it.
 * : Fasteners are grouped in several toolbars. This is the default layout.
 * : Fasteners are grouped in toolbars with flyouts.
 * 1) Restart FreeCAD.

Usage
Fasteners can be attached or unattached. Attached fasteners have a, a circular edge, and their is dynamically linked to that object. The Fasteners Move command can be used to attach or detach a fastener.

Unattached fasteners

 * 1) Select the desired fastener by clicking its button or by picking it from the menu.
 * 2) A fastener is created at the origin.
 * 3) Optionally change the dimensions and other properties of the fastener:
 * 4) Select the fastener.
 * 5) Go to the  tab of the Property editor.
 * 6) Change the required properties.

Attached fasteners



 * 1) Specify if the selected holes are tap holes or pass holes by selecting [[Image:Fasteners_MatchTypeInner.svg|16px]] Fasteners MatchTypeInner or [[Image:Fasteners_MatchTypeOuter.svg|16px]] Fasteners MatchTypeOuter respectively (not used for countersunk screws).
 * 2) Select one or more circular edges and/or faces with circular edges. For countersunk screws the top edge of the chamfered hole must be selected.
 * 3) Select the desired fastener by clicking its button or by picking it from the menu.
 * 4) A fastener is attached to each of the selected circular edges.
 * 5) The default dimensions of each fastener depend on the radius of the circular edge it is attached to. Countersunk screws are matched by their head diameter, other fasteners are matched by their shaft diameter.
 * 6) Optionally change the dimensions and other properties of the fasteners. See above.
 * 7) Fasteners that appear upside-down can be inverted with the [[Image:Fasteners_Flip.svg|16px]] Fasteners Flip command or by changing their  property.
 * 8) Optionally change the  property to create space between the fasteners and the edges they are attached to.
