You can insert additional DESCn attributes on your symbol and edit them with any attribute editing tool, but AutoCAD Electrical does not process them. The attribute names are DESC1, DESC2, and DESC3 and generally appear on both parent/stand-alone and child contact symbols. You can insert three lines of description text up to 60 characters long. At insertion time the width of the symbol is determined by reading the locations of its wire connection attributes (attributes with name X?TERMn).Ī symbol can have hundreds of connection points and a terminal pin number attribute tied to each (use suffix codes beginning with "01" and ending with "ZZ"). Though it is not mandatory, it helps AutoCAD Electrical determine the correct orientation for alignment with an underlying wire at insertion time. Now you go to the directory for the library symbols you are using and open the block. In properties, you get the name for the block. If you already have the block inserted, you can skip inserting it again and just select it and go to the properties. The AutoCAD Electrical library symbols generally have their origin points centered between the first (or only) pair of wire connection point attributes. The best way to edit a block is to insert it into a dwg, then select it and go to the properties. A wire connection pigtail is mandatory when you insert a short pigtail at a wire connection point that has no other visible symbol geometry nearby since AutoCAD Electrical must see something tangible on a symbol at a wire connection point.
Pigtails can defeat the AutoCAD Electrical SCOOT command and automatic wire numbering when two symbols with pigtails bump up against each other. You can manually enter the file name of the new symbol using Type it on the main icon menu page.Avoid putting wire pigtails on your new symbols. Try to insert your new symbol into an existing piece of wire. To test it, call up a new or existing AutoCAD Electrical drawing.
Delete unneeded attribute definitions and graphics.Insert any pre-defined terminal pin, description, or catalog number attribute values. Use DDEDIT to change the TAG1 or TAG2 and the FAMILY attribute values to the family code.Make sure that you keep terminal pin number text paired with its wire connection attribute (the last two digits of each attribute name must match, "X4TERM01" wire connection point attribute matched with "TERM01" terminal pin number text attribute). Reuse attribute definitions from the exploded symbol.Consider the number of wire connection points, rating attributes, and whether your new symbol is a parent symbol (attribute TAG1) or a child symbol (attribute TAG2). Insert an exploded copy of an existing AutoCAD Electrical symbol that somewhat resembles what you need in the new symbol.Open a new drawing using the appropriate symbol name.
