   System.string MenuItem,
   System.int Position,
   System.string MenuCallback,
   System.string MenuEnableMethod,
   System.string HintString,
   System.string BitmapFilePath
System.int AddMenuItem4( 
&   System.int DocumentType,
&   System.int Cookie,
&   System.String^ MenuItem,
&   System.int Position,
&   System.String^ MenuCallback,
&   System.String^ MenuEnableMethod,
&   System.String^ HintString,
&   System.String^ BitmapFilePath



Document type to which the menu item is to be added as defined by swDocumentTypes_e

Cookie specified as defined in ISwAddin::ConnectToSW

Menu string ("menuItem@subMenuString@menuString"); SolidWorks creates menus and submenus only if they do not already exist

NOTE: Use the & symbol to include an accelerator key, e.g, "MyItem@&File" adds MyItem to the File menu with an accelerator key. To display the accelerator key, press the Alt key in SolidWorks. The accelerator key is underlined.


Position at which to add the new menu item

The first item is at position 0; if Position is 1, the new menu item is added to the bottom of the list; this argument specifies the position of the menu item in relation to its immediate parent menu


Function to call when this menu item is selected (see Remarks)


Optional function that controls the state of the menu item.

If specified, SolidWorks:

  • Calls this function before displaying the menu

  • Display of the menu item is controlled by the return value of MenuEnableMethod

If MenuEnableMethod returns...

Then SolidWorks...


Deselects and disables the menu item


Deselects and enables the menu item; this is the default menu state if no update function is specified


Selects and disables the menu item


Selects and enables the menu item

(See Remarks)


Text to show in the SolidWorks status bar when the user moves their mouse over this menu item; if you specify a HintString, it must be preceded by a comma


Path and filename of bitmap

Return Value

SolidWorks runtime command ID or -1 if the method fails


See Add-in Callback and Enable Methods to learn how to specify MenuCallback and MenuEnableMethod.

For information about using this method with the ISwAddin object, see Using ISwAddin to Create a SolidWorks Add-in.

The bitmap must be 16w x 16h x 256 colors. Transparency is RGB (192, 192, 192).

You can add a new menu to any one of the four SolidWorks frames (main, part, assembly, or drawing). To do this, call this method with the appropriate argument in the DocumentType parameter. For example, if you want your menu to be available when a part document is active, then call this method and pass swDocPART as the first argument. After you have added your menu to the part frame, you do not need to do it again during the current SolidWorks session. Once a part document is activated by the user, SolidWorks automatically displays your menu option.

To add a menu separator:

  • leave the text for the menu item blank, so that the menu string for the MenuItem argument starts with the at-sign symbol ( @):



  • specify an existing method for the MenuCallback argument. This method is never called, so its implementation can be empty.

  • specify empty strings for the MenuEnableMethod, HintString, and bitmapFilePath arguments.
