Selection Toolbar

The selection toolbar, located in the data explorer, contains tools to modify how you select objects and data in BlastLogic. You can select data at the object level or the primitive level (points, edges, facets and cells). When you select an object, BlastLogic highlights the object name in the data explorer. When you select primitives, BlastLogic highlights them in the view window. A view window that contains the selected objects or primitives will be gain a blue outline.

The table below summarises the tools in the selection toolbar:
