I have a drawing of a component that I imported from the manufacturer. It is not set up for AutoCAD Electrical (i.e. no attributes such as item number). Is it possible to create a Balloon and Leader for this component?
You must at least have attributes P_TAG1, MFG, CAT, and P_ITEM. Then you can assign an item number and add a balloon.
Hint: Enter the part number for this device into the Footprint Lookup database. Map it to your footprint. Insert the footprint from the schematic list and AutoCAD Electrical will automatically push the data from the schematic symbol into the footprint. It automatically adds necessary attributes for visible data and will add the rest as xdata. It functions that way out of the box for the built-in footprint blocks.
I recommend using the Symbol Builder utility and add the necessary attributes to all footprints. This way you control default location and visibility state of the attributes.
