Determines the default actions when you drag a symbol into the document. You can override the settings on this tab when you drag a symbol. You can press Ctrl to embed the symbol or Ctrl + Shift to link the symbol.
Drag and Drop Default - Specifies actions when you drag a symbol into the document.
Embed - Sets the default action so that the symbol embeds when you drag it on the drawing sheet. Embedding the symbol means that the software places a copy of the symbol in the document. If you edit one instance of the embedded symbol in a document, all copies of that symbol within the current document reflect those changes.
Link - Sets the default action so that the symbol is linked when you drag it into the document. Linking the symbol allows you to edit the original symbol document. The symbol that you placed on the drawing sheet updates automatically. If you edit the symbol inside the active document, those changes are saved in the .sym document on your computer.
