Level Mask dialog box
Use the Level Mask dialog box to set a level mask. A level mask excludes from chaining all entities except those that reside on any of the levels you select for the mask. When you first set a level mask, Mastercam automatically selects all levels used in the current part file.
- In the Level list, select each level that has entities you wish to chain. A check mark indicates that an item is selected.
- To select an additional item, [Ctrl+click] an empty checkbox
- To clear a selection, [Ctrl+click] a selected checkbox.
- Choose Same as to select a level by choosing an entity in the graphics window.
- Choose Select all to select all levels.
- Choose Clear all to clear all level selections.
- Toggle the Plus/Minus button to include ([+]) or exclude ([-]) the selected levels during masking.
