PATTERN allows you to store a part-independent file
containing geometry, dimensions, notes, labels, and
crosshatching. You can retrieve a pattern at any time and
add it to the part that you are working on. Saving a part 
as a pattern file allows you to recall and display it at 
any angle, in any scale, and to any level. This capability
is extremely useful when you are creating a layout.

Choose one of the following options:

CREATE - to store entities as a pattern by selecting the
desired entity(ies) for the pattern file, using a 
Selection Menu option.

Indicate a base position for your pattern, using a 
Position Menu option. This base position is used for 
placing the pattern in other parts.

Enter a valid filename and press <Enter>, or accept the
default name by pressing <Enter>. If you enter the 
filename of an existing pattern file, you are prompted 
to indicate whether you want to replace the existing file. 
Choose an option from the NO/YES menu. 

RETRIEV - to retrieve a previously saved pattern file.

Enter the name of an existing pattern file, without an
extension, and press <Enter>. If you include an extension
(e.g., .ptn), it is ignored.

Specify whether or not the pattern file entities are to be
grouped. If you choose to group the entities, assign a
group name and, if necessary, a subgroup number, and press
<Enter>.

Set the level assignments for entities in the pattern file
in one of the following ways:

- by assigning all entities in the pattern file to the
current active level when retrieved (CUR-LEV).

- by retaining the level assignment that each entity in 
the pattern file had when the pattern file was created 
(ENT-LEV).

- by assigning all entities in the pattern file to a 
specified level (KEY-IN).

Enter a new level number for the pattern file entities.
Enter the desired level number (1-256) and press <Enter>,
or just press <Enter> to assign the entities to the 
current active level.


- by calculating a new level number for each entity in
the pattern file by adding a user-specified integer to 
each entity's current level number (OFFSET).

Enter a positive or negative integer for the desired 
offset factor and press <Enter>, or just press <Enter> to
retain the level assignments that were in effect when the 
pattern file was created.

If the offset calculation results in an invalid level
number (i.e., less than 1, greater than 256), you are
prompted to press <Enter> and to enter a new offset
factor.

With the DETAIL, SET, AUTO UP switch set to YES, the scale
factor is applied to all entities in the pattern file
except the displayed and actual values of angular
dimensions, and the displayed values of manually entered
dimensions.

Enter a scale factor for the pattern file and press
<Enter>. To accept the default value in parentheses, press
<Enter>.

The pattern can be rotated by entering a new rotation
angle. Positive angle values move in a counter-clockwise
direction. Negative angle values move clockwise. Enter a
rotation angle and press <Enter>, or accept the current
default by pressing <Enter>.

Locate a base position for the pattern within the current
part by selecting an option from a Position Menu option.

The pattern is displayed in the current part file, at the
specified scale and rotation angle.


LIST/RTV (list/retrieve) - to list, select, and retrieve
pattern files from a designated directory.

Enter the pathname for the pattern file directory, and
press <Enter>. The default path in parentheses is the
pattern file directory assigned in the CONFIG program. To
accept the default directory, press <Enter>.

A listing of all pattern filenames in the designated
directory is displayed on the screen. If you selected a
VERBOSE filename listing (FILES, LIST FMT, VERBOSE),
detailed display of information is displayed.

Choose the desired filename.

Choose from the NO/YES menu to specify whether or not the
pattern file entities are to be grouped. If you choose YES
to group the entities, you are then prompted to assign a
group name and, if necessary, a subgroup number, and press
<Enter>.

Set the level assignments for entities in the pattern file
in one of the following ways:

- by assigning all entities in the pattern file a to the
current active level when retrieved (CUR-LEV).

- by retaining the level assignment that each entity
in the pattern file had when the pattern file was created.
(ENT-LEV)

- by assigning all entities in the pattern file to a
user-specified level. (KEY-IN)

- by calculating a new level number for each entity in
the pattern file by adding a user-specified integer to 
each entity's current level number.(OFFSET)

With the DETAIL, SET, AUTO UP switch set to YES, the scale
factor is applied to all entities in the pattern file
except the displayed and actual values of angular
dimensions, and the displayed values of manually entered
dimensions.

Enter a scale factor for the pattern file and press 
<Enter>. To accept the default value in parentheses, press 
<Enter>. 

The pattern can be rotated by entering a new rotation 
angle. Positive angle values move in a counter-clockwise 
direction. Negative angle values move clockwise. Enter a 
value for the rotation angle and press <Enter>, or accept 
the default value by pressing <Enter>.

Locate a base position for the pattern within the current
part by selecting an option from a Position Menu option.

The pattern is displayed in the current part file, at the
specified scale and rotation angle.
