Select Filter
The Select Filter page of the View Options dialog box allows you to disable selection of object types. For instance, you want to remove all vias, but leave the rest of your circuit intact. You would click on the Only Objects Checked Below radio button in the page and set only the Vias checkbox. Then preform a Select - Select All , followed by an Edit - Delete.
All objects: Clicking on this radio button will make all items available for selection.
Only objects checked below: Clicking on this radio button will allow you to choose items for editing selection.
The remaining checkboxes appear next to the item which is enabled or disabled by selecting that checkbox.
Click on the Uncheck all button to clear all the checkboxes and on the Check all button to select all the objects.
