Create and Modify Dead Joint Symbols

Dead joint symbols enable you to specify requirements for dead joint seams fabricated using:

  • Soldering
  • Gluing
  • Stitching
  • Stitching with staples - overlapping joints
  • Stitching with staples - contour joints

If you specify joint annotation text, AutoCAD Mechanical aligns the text to a horizontal reference line at the end of the leader line. If you do not specify any joint annotation text, AutoCAD Mechanical does not draw a reference line.

You can save the settings of a symbol to the symbol library and reuse the symbol from there. This eliminates the need to re-specify requirements every time you create a symbol. This can be useful, especially in the light of the many types of joints the dead joint symbol supports.

Drafting standards prohibit the use of multiple leaders on dead joint symbols, so AutoCAD Mechanical does not allow you to use the AMSYMLEADER command on dead joint symbols. Furthermore, because the joint type is specified on the leader itself, AutoCAD Mechanical does not allow you to create symbols without a leader as well. On the leader line, you can drag the grip point adjacent to the leader symbol to change its position along the leader. AutoCAD Mechanical ensures that neither the leader arrow nor the all around designation (if one exists) are overlapped.

Supported Drafting Standards

  • GOST 2.313-82 (1982)

Commands
AMDEADJOINT

Creates a dead joint symbol.

 Ribbon: Home tab Annotate panel Symbol drop-down GOST Dead Joint. Not available on the ribbon in the current workspace.
 Toolbar: Symbols
 Menu: Annotate Symbols Dead JointDoes not exist in the menu in the current workspace.
 Command entry: amdeadjoint

You can use this symbol to specify the requirements for dead joint seams created by soldering, gluing, stitching, and stitching with staples. This symbol is available only with the GOST standard.

COMMAND LINE OPTIONS

Select Object to attach or [Library]: Select an object in the drawing to attach the symbol to. If you do not want to attach the symbol to any object, click in the drawing area to select the start point of the leader. In this case the prompt requesting you to specify the start point does not appear. To insert a dead joint symbol directly from the symbol library enter L.

Object to attach

Attaches the symbol to an object. Subsequent prompts differ depending on the type of object you attach to

Line selected

Attaches the symbol to a line and allows you to move the crosshairs along the line so that you can specify a start point for the leader.

 

Specify start point: Specify the start point of the leader.

 

Specify next point or [startPoint]: Specify the position to place the symbol or Enter P to return to the previous prompt and respecify the start point.

TipTo make the first leader segment perpendicular to the attached line, move the cross hairs so that the leader is approximately perpendicular, and track along the alignment path that is displayed.
     

Arc, circle, ellipse or spline selected

Attaches the symbol to the selected object and allows you to specify the next point for the leader. The start point is automatically determined based on the selected point and the first leader segment being perpendicular to the attached object.

 

Specify next point or [startPoint]: Specify the position to place the symbol or Enter P to fix the start point.

NoteAutoCAD Mechanical forces the first leader segment to be perpendicular to the attached line. To override this restriction, press the Toggle Symbol Leader Orthogonal Mode key (SHIFT + F, by default) as you drag the crosshairs.

Library

Specifies that the symbol text is to be obtained from the symbol library

Enter symbol name or [?] <Default symbol name>: Enter the name of the symbol library item or enter ? to list the names of all the dead joint symbols in the symbol library. Press ENTER to accept the default symbol. If no default exists, pressing ENTER lists the names of all the dead joint symbols in the symbol library.

Select object to attach or [Library]: Select an object in the drawing to which to attach the symbol. If you do not want to attach the symbol to any object, click in the drawing area to select the start point of the leader. In this case, the prompt requesting you to specify the start point does not appear.

Specify start point: Specify the start point of the leader (usually the joint).

Specify next point: Specify the next vertex of the leader. The Dead Joint dialog box appears as soon as you specify the next vertex of the leader.

Dead Joint dialog box

Use this dialog box to specify the requirements displayed in the dead joint symbol.

NoteSome options in this dialog box are named only in tooltips.

Symbol Tab

 
 

Options

 

 

Flip sides

Flips the position of the joint annotation text, such that it is placed below the reference line. The icon to the left of the check box shows the result of your selection. This option is not available if the joint type is set to stitching.

 

 

Flip symbol

Flips the symbol so that the joint annotation text appears to the left of the arrow. The icon to the left of the check box shows the result of your selection.

 

Library

Lists all the dead joint symbols for the active drafting standard/revision in the symbol library. When you move the pointer over an item, all settings for that item appear in a tooltip. Each item in the library is associated with a context-sensitive menu.

   

Menu options

     

Load

Loads the selected symbol from the library. The current settings in the Dead Joint dialog box are overwritten. Load operations ignore the Flip symbol check box.

     

Update

Overwrites the selected symbol in the library with the current settings of the Dead Joint dialog box. The preview updates to reflect the new settings. The name of the symbol and default status do not change.

     

Delete

Removes the selected symbol from the library.

     

Rename

Makes the symbol name editable. AutoCAD Mechanical validates the name to ensure that the symbol names are unique.

     

Set default

Makes the selected symbol the default symbol of the library. A blue check mark appears next to the symbol to indicate that it is the default symbol. The next time you create a dead joint symbol, the default symbol loads automatically.

     

Remove default

Removes the default status of the selected symbol. This menu option is available only on the default symbol. When there is no default symbol selected, the Dead Joint dialog box defaults to the settings of the dead joint symbol you created or edited most recently.

   

Add

Saves current settings to the symbol library as a new item in the library. A prompt enables you to name the new item.

   

Import

Imports the dead joint symbols from the symbol library of another drawing. You can only import symbols of the same standard and revision as the dead joint symbol you are editing.

 

Requirements

   

Insert symbol

Displays a palette to enable you to insert a special character (for example, the degree symbol) in the joint annotation box, at the current cursor position.

   

Joint annotation

Provides a space to specify the joint annotation text. Typically, this box contains a reference to the technical requirements of the joint.

   

Second joint annotation

Provides a space to specify additional joint annotation text. This box is visible only if the joint type is set to stitching. Typically, this box specifies the number of stitches and the distance between them.

   

All-around

Inserts the all around indication to the symbol.

   

Leader symbol

Displays a palette of permanent joint symbols to enable you to specify the joint type. A tooltip describes what each symbol in the palette represents. The following joint types are supported:

  • Soldering
  • Gluing
  • Stitching
  • Stitching with staples (overlapping)
  • Stitching with staples (contour joint)
 

Clear

Clears all data and returns the dialog box options to its default settings.

Leader and Text tab

 

Arrowhead

Specifies the type of the leader arrowhead. When the arrowhead is set to By Standard, it acquires the arrowhead from the current drafting standard. Thereafter, if you change the settings for the drafting standard, the arrowhead for this symbol updates automatically.

 

Edit object attachment

 

 

Attach

Attaches the symbol to an object in the drawing. When attached, if you move the object the symbol moves with it.

 

 

Detach

Detaches the symbol. The symbol becomes a free-standing object.
