The Masking Menu allows you to screen a geometric entity 
(e.g. lines), drafting entity (e.g. dimensions), or
attribute type (e.g. line width), to increase selection 
reliability and speed when the entities you want to select
are part of a complex design.

Mask entities by choosing from the following options:

GEOM (geometry) - allows you to select a single entity or 
a group of entities of a certain geometric type 
(e.g. lines).

DETAIL - allows you to select a single entity or a group
of entities that are details or notes.

COLOR - allows you to select a single entity or a group of
entities that are the same color.

L-TYPE - allows you to select a single entity or a group of
entities that have the same line type.

L-WIDTH - allows you to select a single entity or a group 
of entities that have the same line width.

PEN # - allows you to select a single entity or a group of
entities that have the same pen number.

DONE - after you choose the type of entities you want to 
select and they are selected, choose done to signal
the end of selection. The selected entities are then
changed or deleted.


Choose the type of entities you want to mask.

Select the entity or entities using the Selection Menu.

Choose the DONE option. All selected entities are changed 
or deleted.
