Otherwise, extended entity data is used with names based on the data names listed here but with a VIA_WD_ prefix (ex: 'VIA_WD_DESC1').

If the footprint block has an attribute with any name listed here, that attribute is used for the specific piece of data. The following is a list of footprint block data names that are inserted or read. Panel nameplate - block must carry a minimum of one of the following: Terminal footprint - block must carry a minimum of one of the following: Attribute: P_TAG1 (and no attribute NP present).The following are the minimum requirements for a block to be recognised as a panel footprint, terminal, or nameplate.Ĭomponent footprint - block must carry a minimum of one of the following: When AutoCAD Electrical inserts such a block footprint symbol, the needed intelligence is added. In either case, these libraries can be used as is. You may have your own in-house footprints set up. Some manufacturers provide free, to-scale mechanical libraries of their control components, all in .dwg format. If the attributes are not found, AutoCAD Electrical saves the values as extended entity data or referred to as Xdata. AutoCAD Electrical looks for certain attributes to hold the electrical data when a footprint is inserted.

There are no attribute or symbol naming requirements for the mechanical footprint block symbols. In this example, I’m going to create a Siemens circuit breaker as shown below:
