may be a line could be in revision 1 released
the new version need to change the line of 10 mm ,
so we have to take care of the old version and create a new version of
the some line.
so 2 record are ready for this entity

This is an example of a line story ..

step 1: create a new entity
01 - Line - 10,10,10,100 - 1 -  Active
step 2: release the version 1 of the drawing 
01 - Line - 10,10,10,100 - 1 -  Released
step 3: Create a new version of the drawing (Version 2) and mark as
old_Released the old version of the line
01 - Line - 10,10,10,100 - 1 -  Old_Released
02 - Line - 10,10,10,110 - 2 -  Active
