Connection Component Edit window ( Modeling )

The Connection Component Edit window contains user-editable settings for system connections , which are connections that have been created by connection design . Member custom components (which are parametrically generated) should not be confused with connection components.
Note: The [ Left end ] banner shown above will read [ Right end ] if the component is on the right end of a member. A column's bottom end is its left end. Making changes to this window automatically updates equivalent settings on the left or right end of the member edit window.

To open the Connection Component Edit window :

VIDEO Double-clicking a system connection material, connection bolt or connection weld opens that connection's Connection Component Edit window. (Recorded in SDS2 Detailing , v2015.)

Method 1 : With the ' Connection Components ' filter or ' Default ' or ' All ' filter selected, double-click a system connection material to open the Connection Component Edit window for that connection.

Method 2 : In the Model Tree , with " View By " set to ' Member Piecemark ' or ' Member Number ', double-click a member's " Left End " or " Right End ." The Connection Component Edit window opens for the system connection on that end of the member.

Note: For a custom component , a listing is also provided in the Model Tree . That custom component's listing will be named after the custom component. It will not be named " Left End " or " Right End ."

Method 3 : Multi-editing of connection components associated with different members of the same type (beams, columns, etc.) can be accomplished by selecting the components in the model (or the Model Tree ), then right-clicking and choosing " Edit " on the menu.

sets all " End preparations " and " Connection design locks " under " Left end settings " or " Right end settings " (as the case may be) to a locked state, thus preventing the connection from being altered by connection design . You will still be able to make changes to the connection by unlocking ( ) particular lockable fields (so that connection design can make entries to that field) or by you yourself making different entries to the locked fields.

unlocks all connection design locks (lockables) associated with the left or right end (as the case may be). This results in a connection that is fully designed by connection design, without any user entries to connection design locks.

Left End
       " Save As User Defined Connection

VIDEO Connection design locks are used to adjust a shear plate so that it matches a definition in Standard Shear Plates . A user defined connection is then saved from the Connection Component Edit window for that shear plate and applied to a different beam, with a different framing condition. The same user defined connection is then employed as an auto standard connection . All beams are processed , and the user defined connection is automatically applied to all beams under the ' WFlg Beam to WFlg Column (Flg perp) ' framing condition. (Recorded in SDS2 Detailing , v2015.)

  " Save As User Defined Connection " is available as a button when you are editing one component at a time. It is not available (not visible) if you are editing multiple components .

The button allows you to save as a user defined connection changes that you have made to " Connection design locks " and " End preparations ." You can overwrite a previously saved user defined connection or create an entirely new user defined connection.

To overwrite a previously saved user defined connection:

1 . After you have set the " Connection design locks " and " End preparations " for this connection component, press the button under " Left end settings " or its " Right end settings ."

2 . Select one of the user defined connections that are listed on the " Select One User Defined Connection " dialog. Press " OK ."

3 . On the yes-no dialog that opens, press " Yes " to overwrite the connection.

Overwrite existing user defined connection 'xxx'?

4 . The user defined connection you selected will be overwritten with this connection component's settings.

To create an entirely new user defined connection:

1 . After you have set the " Connection design locks " and " End preparations " for this component, press the button under " Left end settings " or " Right end settings ."

2 . Press the " New... " button.

to create a new user defined connection

3 . Type in the name that you want to give the new user defined connection, then press " OK ."

New user defined connection:

4 . The new user defined connection you just created will store settings from this window.

" Copy " " Paste " " Save " " Load    

" Copy " " Paste " " Save " " Load " form buttons:

  • These are sometimes referred to as "form buttons."
  • You can use these buttons to save and copy connections. The buttons operate on all fields under all leaves that are under the [ Left end ] or [ Right end ] heading.
  • Tip: Right-click a " Load " button to get a list of recently created forms that can be applied to the section which that " Load " button governs. Selecting the name of a form from the list populates the fields in that section with the form settings that were saved under that name.
  • For more information, see "Copy" "Paste" "Save" "Load" ( ).

    Information ----------------------------------------------------------------------

If you are in a multi-user environment, it is possible that you may find yourself on a connection component edit window at the same time that somebody else in your current Job is adding a member that connects to the member that the connection you are editing is associated with. As a result, process on the fly will be locked from accessing information about that other member, and the following message will be generated:

 On-the-fly process failed 

If you are editing multiple connection components and the members those components belong to have different connection failed or connection-changed messages, a banner like the following is displayed:

  Multiple failed and/or changed connection messages 

The " Connection design locks set " banner notifies you that at least one setting in the connection is locked ( ):

  Connection design locks set. 

VIDEO Sections of a window (" leaves ") within which at least one locked variable resides are marked in the navigation tree with a locked icon ( ). (Recorded in SDS2 Detailing , v2015.)

Search: Connection design locks set
Status Display: Search > Connection design locks set

A red end connection failed message like that shown below indicates a connection failure . Along with the failed message, you will find a  button for context-sensitive help about the message.

 Beam web shear capacity failed

Connection failure messages by member type:
[ beam ] [ column ] [ horizontal brace ] [ vertical brace ] [ joist ]

  launches the User and Site Options > General > " Help browser " and gives you context-sensitive help about a connection failed message . If there is no connection failed message, this button will not be shown. A connection failed message may be generated, for example, when " Left/Right End Limit State " analysis reveals that a connection cannot carry the load that the connection's member is subjected to. The various limit states associated with a connection are tested during connection design .

Report Writer: Member.LeftEnd.MoreEnd.Conditions.ConnectionFailError
Advanced Selection: m.Ends[0].ConnectionHasFailed

VIDEO When a connection has failed , you don't get any connection materials. Forcing the connection gets you connection materials. The Connection Design Calculations report includes a warning when a connection has been forced. (Recorded in SDS2 Detailing , v2015.)

' Force ' applies when the connection has failed , which results in your not getting any connection materials in the 3D model. To get connection materials so that you can review the situation and make needed changes, check the box for " Force ," then press " OK " (so that Create Solids is performed). The Connection Design Calculations report (and Expanded Connection Design Calculations ) will include a warning notifying the reader of that report that the connection has been forced.


' Graphical ' may have been automatically set to " Graphical " as a result of a user employing modeling operations to modify the system connection on this end of the member, thus making it graphical . A graphical connection will not be changed by connection design . On this window, you will not be able to change any of that connection's " Connection design locks " or " End preparations ." The Connection Design Calculations report (and Expanded Connection Design Calculations ) will include the warning " GRAPHICAL CONNECTION -- STRENGTH CALCULATIONS NOT GENERATED ." If " Graphical " is checked and you switch it to " Graphical " then press " OK " (so that Create Solids is performed), user-added modifications to that connection will be overwritten or erased. For example, user-added holes will disappear. On the General Information window for each of the connection materials, you will see that switching from " Graphical " to " Graphical " caused the connection materials that were regenerated to be changed from " User modified connection material " to " System created connection material ."

  End preparations ---------------------------------------------------------------

VIDEO A connection is double-clicked to open the Connection Component Edit window. In " End preparations ," the bottom cope is changed to a cut flange flush and saved (with the entire connection) as a new user defined connection. The new user defined connection is then applied to another member. (Recorded in SDS2 Detailing , v2015.)

Tip: If you " Save As User Defined Connections " from the Connection Component Edit window, end preparation settings will be included in the user defined connection.

To change an end preparation setting, first set it to locked ( ).

Some examples of the connection design lock sections that you might see on the Connection Component Edit window for a beam connection.

    Left/Right end limit state ----------------------------------------------------

Limit states for a clip angle connection on the left end of a beam. The values shown represent the strength capacity of the connection or of the supported member (this beam) or of the supporting member. In this example, the connection passes.
  • A limit state is a potential connection failure mode.
  • Limit states are updated during connection design. Since connection design takes place on-the-fly, whenever a change is made to a connection design lock on this window, the limit states are updated continuously, as you make changes to this window.
  • Each " Value " reported in the example above represents the strength of the connection or of the beam itself or of its supporting member with respect to a particular limit state.

To close the Connection Component Edit window :


" Edit Member " does the same thing as " Cancel ," but also opens the member edit window associated with the connection component that you are editing.

" OK " (or the Enter key) closes the Connection Component Edit window and saves any changes you have made on the window to the member file of the affected member.

Solids on "OK": If the appropriate choice is made to User and Site Options > Modeling >" Automatically process after modeling operation ," then this member will automatically be regenerated ( Create Solids will take place) after your press " OK ." Otherwise, you will have to manually Process and Create Solids in order for changes you made on this window to be fully updated in the 3D model.

" Cancel " (or the Esc key or the button) closes the Connection Component Edit window without saving any changes that you have made.

" Reset " undoes all changes made to this window since you first opened it. The window remains open.
