laminate thickness: max thickness / off
|
Enter a value for the laminate thickness (LAMTHK) maximum, or toggle the switch to off.
|
ply thickness: no. of constraints
|
Displays the number of constraints for ply thickness (PLYTHK). To modify this number, click Edit.
|
ply percentage: no. of constraints
|
Displays the number of constraints for ply thickness percentage (PLYPCT). To modify this number, click Edit.
|
balance: no. of constraints
|
Displays the number of constraints for balancing (BALANCE). To modify this number, click Edit.
|
constant: no. of constraints
|
Displays the number of constraints for constant thickness (CONST). To modify this number, click Edit.
|
ply drop-off: no. of constraints
|
Displays the number of constraints for ply drop-off (PLYDRP). To modify this number, click Edit.
|
|
The Edit Card Image viewer is not a subpanel, but rather a separate feature accessed from within the Parameters subpanel by clicking edit.

|
return
|
Exit the panel.
|
review
|
Highlight the specified constraint, and displays its current characteristics in the input fields.
|
update
|
Update the selected constraint's characteristics or parameters to match your inputs.
