Introduction

(Back to Top)

The fastener assembly is a one dimensional collection of entities initially designed for the needs of glulam and Post & Beam Timberframe type construction.

There is the main component, which is typically the shaft of the fastener, with one or more subcomponents located either at the ‘head’ end of the shaft or at the ‘tails’ end.


Database driven Fastener Styles

Fastener Norms
Fastener Type
Fastener Sub types
Fastener Models 
   
An extensive database is already created that has several categories and allows filtering views based on previous selections.
As a style based assembly, the user must initially set up their styles. To do so do the following:
  • Select Style Manager/hsbcad Object/hsbcad Fastener Assembly style/right click/New


Once you’ve given an appropriate style name select the Edit Style button on the right side of this dialog box.
The Fastener dialog box will open.



You have different selection boxes to filter from - Norms – Types – Sub Types – Models.

Fastener Norms

(Back to Database driven Fastener Styles

The International Standardization Organization, widely known as ISO, is an international standard-setting body composed of representatives from various national standards
organizations. DIN, Deutsches Institut für Normung (in English, the German Institute for Standardization) is the German national organization for standardization and is that country's ISO member
body. In general, each country or economy has a single recognized National Standards Body (NSB).
The American National Standards Institute (ANSI) is the US NSB member of ISO.


Fastener Type

(Back to Database driven Fastener Styles

The second property, on which the database filters, is the fastener type.
Types include such items as Bolt, Nuts, Washers, Screws, etc.
This refers to the Primary Fastener component, typically represented by the single shaft of the fastener.
Once the user has selected a Fastener Type, the subsequent selection lists below are filtered to aid with selection of matching items.


Fastener Sub types

(Back to Database driven Fastener Styles)

The third property on which the database filters, is the Sub types.


Fastener Models

(Back to Database driven Fastener Styles)

The forth property on which the database filters, are the Models
This metric stud bolt to nut table is meant to help determine the correct size bolt or nut for your filtering.



Once you have filtered the requirements, drag and drop the hardware from the left side to the right side (main Shaft Components) of this dialog box.
The hardware can now be seen in the right hand side.



Do the same for the Head and Tail components.
The main component (the shaft component) will have multiple lengths stored in the database, to see the different lengths select the pull down button (little arrow) on the right side of the Main Component, a pulldown wil appear.



Once the style is created, go back to your drawing and add a fastener to your drawing by doing the following


Add Fastener command

(Back to Top)

Once you have made your Fastener styles you can add these styles by Add Fasteners.
The command for adding a fastener is hsb_fa_add.

It can also be accessed from the hsbEdit menu under Fastener menu item.
A dialog with a single dropdown is called from which the user selects the Fastener Style to be inserted.




After a fastener assembly is inserted the user can view the properties in the OPM.




Under the General properties (OPM), the Object field displays the current product length of the fastener.
The length of the fastener assembly is controlled by the length of the fastener assembly guide line.
This assembly guide line can react to toolings, such as a Drill line and be manipulated and placed via TSL.

For example, if the host drill line through 2 ply beam is lengthened due to adding a ply or changing the thickness of the beam, the fastener assembly length will automatically be
adjusted. This is the standard behavior assuming the Length Selection property on the Fastener Style remains set to the default Automatic value. However, if the user changes the
Length Selection property to User Defined, a dropdown becomes active on the Object field allowing the user to manually override the product length selected from the database.

NOTE:
The automated lengthening of the fastener assembly line must be controlled by an hsb tool that can react to changes in the beam entity.

For example, the Free drill tool will not trigger an automated length adjustment of the fastener entity because it does not natively react to the beam.
If you attach the Fastener Assembly Guide Line to a Surface drill tool which reacts to the beam, then the fastener assembly guide line will automatically be adjusted.


Anchor to guideline

(Back to Top)

Anchor to Guideline is used to anchor fasteners along an existing Fastener Assembly Guideline in the drawing.
This command is hsb_fa_anchorto.




Flip

(Back to Top)

Simply swaps the orientation of the fastener along the axis of the shaft between head and tail ends and is typically done from the right click context menu.
This command is hsb_fa_flip.
