Hi Mike,
please follow those steps:
1. Open (or create) library and put in symbol <new>, change 'Visible' --> 'both'
2. Create a symbol and name the pins as you desire, e.g. D0 through D7. (Pic1)
3. Create a package and name the pads accordingly, e.g. 1 through 8, mark pin no.1 as shown on Pic2. (Use 0 line width and create the arrow using 'polygon'.
4. Create a device: New --> device name and use 'add'. Select the symbol you've created and place it near the center coordinates of the screen. Type in a default name for the device, e.g. 'SV'. Assign package to the device. Connect pins and pads.
When finished the device should look like Pic3.
Regards
Boncuk
