Blank custom symbol in the toolbox when sharing

Question:

I am sharing my schedule with others. However, when I share the schedule, all of my custom bitmap symbols are missing and show up as blank symbols in the toolbox.

Answer:

Custom symbols, by default, are located in a folder on the schedule creator's computer. When sharing with others, each custom symbol needs to be embedded in the schedule.

Double-click each custom symbol in your toolbox.
Embed Above Symbol in File.
Save the schedule and share with others.
