If you need to copy a system family (stair, railing, wall sweep, fascia, gutter, etc.) that has a specific PROFILE embedded, from one project to another.. you can do a copy/paste with confidence.
The system family will copy over and bring with it any profile that is embedded that helps create the shape. Your system family may ERROR when you paste it into the new project.. but the profile makes the transfer just fine.
Example: If you copy a wall sweep.. it will error because it doesn't have a wall to host to in the new project. No biggie. Your profile made the jump and is ready to be used.
