Working with the History Tree

The history tree in the Modeler window lists the active model's structure and grid details, including the model's objects, coordinate systems, default planes, and any object or face lists.

Modeler window's history tree with a model highlighted

You can perform the following tasks with the history tree.

The history tree contains the following model details:

Invalid	Lists all invalid objects
3D Component Names	Lists any 3D components added to the design, listing their Solids, Coordinate Systems, and Planes, separately from objects drawn in the modeler, or imported to the modeler.
Solids	Displays all the model's solid objects and a history of the commands carried out on each object.
Sheets	Displays all the sheets in the model 3D design area. By default, all sheet objects are grouped by a boundary assignment.
Lines	Displays all line objects included in the active model. See Drawing a Line for information on how to draw a line object.
Points	Displays all point objects included in the active model. See Drawing a Point for information on how to draw a point object.
Groups	Displays folders for Groups you have created or imported. See Group Commands for Modeler Objects.
Coordinate Systems	Displays all the coordinate systems for the active model. See Setting Coordinate Systems for more information on this model detail.
Planes	Displays the planes for all the coordinate systems. When you create a coordinate system, default planes are created on its xy, yz, and xz planes.
Lists	Displays the object or face lists for the active model. By default, a list called AllObjects appears. Creating an object list is a convenient way to identify a group of objects for a field plot or calculation. Creating a face list is a convenient way to identify a specific set of surfaces for a field plot or calculation. See Creating an Object List.

Note: While objects created in Maxwell can always be classed in the history tree as either a solid, sheet, or wire, some imported objects may have mixture of these. Such objects are placed in an Unclassified folder in the history tree.
