Abstract: Examples can include a system for filtering selections made within a computer-aided design (“CAD”) application. A plugin can generate a filter designer window that is displayed on a graphical user interface (“GUI”). The plugin can receive criteria for a first filter based on an edit tab that allows the user to select a parameter, operator, and operand. The user can categorize and edit the filters and apply them to the selection. The plugin can loop through elements within a selection box and automatically deselect elements that do not meet the criteria of the first filter. Remaining selected elements can be visually indicated as specified by the first filter.
