Select the object you want to add to the library, click on the triangle next to Create. When the library opens, click Add. Write in the name and the description and BYU. When you want to create an .obp, just select the object in the library and click Export. Important note: when importing, take care about what's selected and whether the Boolean operations are all okay. Otherwise you'll get a lot of errors and something messy later.
