Create a helper assembly with a dummy part and your assembly with the led's.
In the dummy part create an extrude of some thickness and size that will cover the zone your LEDs will be placed. Create a set of hole wizard holes that are constrained to the location of the LEDs.
You can use different size hole wizard holes to differentiate your LEDs or other surface mount components from one another.
The create a drawing and add a hole chart with the x-y locations of your LEDs.
You can save the hole chart to an excel file.
I do this all the time for the weld schedule drawings I create for our shop.
AWESOME!! IT WORKED...THANKS A TON!!!
