Use this option to lock a drawing, preventing any changes to be made.
-
Select the option Utilities > MDS Drawing Lock and the form shown below is displayed.

-
Select the Lock Drawing option and click on Apply to lock the drawing.
-
To unlock a drawing, select Unlock Drawing and click Apply.
A locked drawing will NOT be deleted and/or overwritten via the MDS ABA drawing creation process, even if the MDS support name is selected in the main 'Create MDS Drawing' form.
However the user will have to check the ABA log file, for example, %PDMSABALOG%/Aba_7-June-07_10-52-36.log, for the list of MDS support drawings successfully created or aborted. A typical ABA log file output is shown below.
