Both Trees show hierarchical outline view of geometries and solids existing in the scene. Each geometry/solid branch or node can have a number of subitems, this is often visualized by indentation in a list. A geometry/solid can be expanded to reveal subitems, if any exist, and collapsed to hide subitems. Geometries/Solids Trees allows the user to easily manage and navigate objects in them.
In the image below, the Geometries Tree is shown located at the left-side of the application window, and Solids Tree at the right. Both trees will appear when the Solid Editing dialog is open. Solids are included in the simulation calculations, while geometries are not. Using the functions in the Solid Editing dialog, a user can transfer objects from one tree to the other.
